Nasal Staphylococcus aureus (SA) carriage is associated with SA surgical site and bloodstream infections following a surgical procedure, according to findings from a new prospective, multicenter clinical study published in the August issue of Open Forum Infectious Diseases.

“This was a pan-European study with many hospitals, many different clinical settings, and as far as I’m aware, it hasn’t been done before. [The new study] covers a lot of European countries and a lot of surgical specialties,” said lead author Jan Kluytmans, MD. The study also captures the current state of preventive strategies in surgery, such as changes in air flow, dress, and skin preparation, he added.

The study included 5004 patients from 33 hospitals in ten European countries, of whom 67.3% were found to be SA carriers. The median age was 65 years, and 49.8% of patients were male. Open cardiac, and knee and hip prosthesis surgeries made up the largest fraction, but there were 12 types of surgery included in the study.

There were 100 SA surgical site or blood infections. The researchers found an association between surgical site or blood infection and SA carriage at any site (adjusted hazard ratio [aHR], 4.6; 95% CI, 2.1-10.0) and nasal SA carriage (aHR, 4.2; 95% CI, 2.0-8.6). Extranasal SA carriage was not associated with an increased infection risk.

Each 1-unit increase in nasal bacteria was associated with an increase in infection risk (aHR, 1.23; 95% CI, 1.05-1.43).

A strength of the study is that it is the largest prospective study yet conducted on SA carriage in surgical patients, but the researchers were unable to do a subgroup of methicillin-resistant SA (MRSA) due to small numbers of infections.

The study confirms the value of the decolonization strategy, which the World Health Organization has endorsed with the highest level of scientific evidence that is available in preventive strategies in surgery. WHO strongly recommends decolonization for cardiothoracic and orthopedic surgery using intranasal applications of mupirocin 2% ointment with or without a combination of chlorhexidine gluconate body wash. It has a conditional recommendation for a similar procedure before other types of surgery.

However, “It is not widely practiced, and although that was not a surprise to me, I think it’s really disappointing to see that proven effective strategies are not being practiced,” said Dr. Kluytmans, professor of medical microbiology at University Medical Center Utrecht, Utrecht University, the Netherlands. “If I would come into surgery being a carrier, and not be decolonized, I would really be quite angry because it puts you at risk, which is preventable. I think that’s something we owe to our patients,” he said.

He said that some may have concerns about the potential for decolonization to contribute to antibiotic resistance, but the short-term prophylaxis — typically a few days — should not foster resistance, according to Dr. Kluytmans. “If you use it short term, just before surgery, it has been shown in many studies that resistance isn’t a big problem and it can be monitored.”

The link specifically to SA nasal carriage is a mystery, according to Dr. Kluytmans. “It puzzles me still how it gets from the nares to the wound during surgery. So that’s my million-dollar question that I would like to resolve. We would like to study it, but we haven’t quite a bright idea how to do that,” he said.

The results are compelling, according to Heather Evans, MD, who was asked for comment. “On the face of it, this looks like a no-brainer. We should be decolonizing all patients that go to the operating room, and it’s not a terribly unpleasant thing for a patient to undergo to have decolonization done. Particularly for patients who are at higher risk for having a severe complication, like someone that has an operation that’s involving an implant, for example, I think it really makes a lot of sense to do this low-cost intervention for those patients,” said Dr. Evans, professor of medicine at The Medical University of South Carolina as well as the president of the Surgical Infection Society.

She noted that many facilities test for methicillin-resistant SA, but usual not SA more broadly. “This is a very interesting and compelling study that makes us rethink that, and maybe it isn’t even worth testing to see if you have staph aureus, maybe we should just be putting Betadine in everyone’s nostrils when they come to the operating room. It just seems like it would be a pretty low-cost intervention and something that could potentially have a big impact,” said Dr. Evans.

Although she was impressed by the study, Dr. Evans noted that the researchers tested for carriage at sites unrelated to the surgical site. “It really made me wonder if it would have added even more credibility to the study if there had been a sample taken after surgical prep was done to demonstrate that there is actually no staph aureus present on the skin at the time that the wound was made,” she said.

The question ties into the recent “Trojan horse” hypothesis, which suggests that endemic carriage of bacteria is responsible for most surgical site infections, rather than the long-held belief that operating room contamination is to blame. “That would sort of fly with this study, that the patient is walking around with Staph aureus and not necessarily on their skin or at their surgical site, but it’s endemic in their body,” said Dr. Evans.

Dr. Kluytmans and Dr. Evans have no relevant financial disclosures.

Pertussis cases in the United States have increased fourfold compared with the same time period last year, according to data from the Centers for Disease Control and Prevention (CDC). Reports from several states illustrate this trend, thought to be due to reduced immunity across the country.

The Alaska Department of Health issued a statement on its website about the significant increase in pertussis cases in the state during the summer, with 90 cases in July and 61 in August, compared with 24 in June and a total of 26 cases in 2023.

Similarly, the Florida Department of Health reported a pertussis increase in July 2024 that was higher than the June 2024 case count and also above the previous 5-year average.

Experts in these and other states suggest that several factors are driving the nationwide increase, including the fact that fewer people are consistently wearing masks. The mass masking during the COVID-19 pandemic caused a significant drop in pertussis, but the latest data suggest a return to prepandemic levels, and waning immunity likely plays a role as well.

Pertussis, also known as whooping cough, typically begins with symptoms similar to those of the common cold, including runny nose, sneezing, mild fever, and cough, according to the CDC. However, babies with whooping cough may experience trouble breathing rather than a cough. The coughing fits often associated with pertussis may not start until 2 weeks after the onset of other symptoms, according to the CDC.

Those who have been vaccinated against pertussis can still become infected, but the risk is lower, and the illness, if it occurs, is likely to be milder. Complications such as apnea, pneumonia, and convulsions can occur in babies younger than 1 year, especially if they have not been vaccinated, according to the CDC.
 

Beyond Easing Pandemic Precautions

Many respiratory-based infections dipped during the COVID-19 pandemic, almost certainly from the multifactorial interventions of masking, distancing, and the general lack of comingling, said David J. Cennimo, MD, associate professor of medicine & pediatrics in the Division of Infectious Diseases at Rutgers New Jersey Medical School, Newark, New Jersey, in an interview.

The number of cases of many of these diseases returned to previous levels after COVID-19 restrictions were lifted, he said.

“However, we know pertussis immunity wanes over time. Children get DTaP at 2, 4, 6, and 15 months, and a Tdap booster at 11-12 years old gets them to adulthood,” Dr. Cennimo said. Adults should be getting a Tdap every 10 years, he added.

The latest available CDC data indicate that Tdap vaccine coverage in adults is approximately 40%, which means that there may be a large number of susceptible people who can become infected and propagate to others, said Dr. Cennimo.
 

Not Just the Young Ones

A recent pertussis outbreak among college students in Virginia highlighted the fact that the infection can affect all ages, and that the effectiveness of childhood vaccines may decrease over time. The majority of the recently diagnosed cases occurred in individuals who had been previously vaccinated, according to a press release from the Virginia Department of Health.

Clinical Clues

The initial stage of pertussis infection looks like a common cold with symptoms of upper respiratory infection, Dr. Cennimo told this news organization. “Unless there is reason to suspect pertussis exposure, it would almost certainly be missed,” he noted.

The characteristic barking/seal-like cough is mostly seen in children, said Dr. Cennimo. Adults and children can experience coughing fits that can lead to shortness of breath and/or vomiting, which would raise suspicion for pertussis, but is not universally present, he said. The convalescent stage of pertussis can be prolonged and is characterized by chronic coughing. “In the past, pertussis had been called the 100-day cough,” and at that point, treatment is ineffective, Dr. Cennimo said.

In clinical practice, “I advise everyone to get the Tdap vaccine every 10 years,” and remember that the “Td” is the every 10-year tetanus shot as well, Dr. Cennimo told this news organization. Reassure patients that the Tdap can be given with other vaccines, he said, and remind patients that, as with any of the respiratory illnesses, they should stay home if sick, cover a cough, consider wearing a mask in public, and wash hands frequently, he said. 

Dr. Cennimo had no financial conflicts to disclose.

Whooping cough is surging in the United States, with four times as many cases reported so far this year, compared to all of 2023. 

The CDC said 14,569 cases had been reported as of Sept. 14, compared to 3475 in all of 2023. 

There were 291 new cases reported for the week ending Sept. 14, with New York having the most cases, 44, followed by Ohio, Pennsylvania, and Oklahoma with 38 each. That’s the most cases in a single week since 2015.

Whooping cough, also called pertussis, is a respiratory illness spread through coughing, sneezing, or breathing very close to another person. Babies are given the DTaP vaccine to protect against whooping cough, diphtheria, and tetanus. Because the vaccine effectiveness wanes faster for whooping cough than the two other illnesses, boosters are recommended every decade or so.
 

Why the Whooping Cough Vaccine Is Important

Whooping cough is a very contagious bacteria, so vaccination is an important step to avoid it.

But many children in their tweens aren’t getting boosters, and that age group is driving the whooping cough outbreak.

“With the increase in vaccine hesitancy that has been going on since the COVID-19 pandemic, we’re seeing outbreaks occurring in kids who are not vaccinated,” Tina Tan, MD, president-elect of the Infectious Diseases Society of America, told NBC News.

Also, people are not social distancing the way they did during the height of the COVID pandemic, when whooping cough numbers went down.

“Levels of pertussis dropped dramatically when we were all masking, and now this huge increase is getting us back to pre-pandemic levels, and probably a little above that,” Thomas Murray, MD, a Yale Medicine pediatric infectious diseases specialist, said in a news release from the school. “It’s a contagious respiratory virus that can spread fairly quickly through the population.”

FDA advisers were scheduled to meet Sept. 20 to discuss developing more effective boosters for whooping cough.

“With the increase in vaccine hesitancy that has been going on since the COVID-19 pandemic, we’re seeing outbreaks occurring in kids who are not vaccinated,” Tina Tan, MD, president-elect of the Infectious Diseases Society of America, told NBC News.

Also, people are not social distancing the way they did during the height of the COVID pandemic, when whooping cough numbers went down.

“Levels of pertussis dropped dramatically when we were all masking, and now this huge increase is getting us back to pre-pandemic levels, and probably a little above that,” Thomas Murray, MD, a Yale Medicine pediatric infectious diseases specialist, said in a news release from the school. “It’s a contagious respiratory virus that can spread fairly quickly through the population.”

FDA advisers were scheduled to meet Sept. 20 to discuss developing more effective boosters for whooping cough.

There’s a very interesting story in the medical press. A few years ago, a plastic surgeon named Edmond Cabbabe was preparing to do a follow-up cosmetic procedure on his wife at Mercy Hospital South, which is a big hospital in the St. Louis, Missouri, area.

He put her on the operating schedule, and he had done that when he had performed the original operation on her. On the day of the surgery, he got a call from the hospital saying the procedure was canceled. They said that the hospital’s policy, maybe a new one, would not allow doctors to operate on family members.

This physician was a past president of the Missouri State Medical Association. I think he was also on the board or president of the American Medical Association (AMA) Foundation. This was a physician not only in a skilled area where he felt confident he could take care of his wife, but also someone who was prominent in medical politics and medical policy.

The AMA forever has had a policy that says don’t treat relatives. This physician basically said, I think that policy is too restrictive, too cautious, and it doesn’t make much sense to continue to say that you can’t treat family and friends.

By implication, he was saying, I know exactly what I’m doing in my field and I know exactly what I’m doing with her procedure. I should have a right to perform it. I think I do a great job and I’d be best for her.

If you look at medical boards, every once in a while in some state, someone is brought up on a charge of doing different things with family members and saying that they’re going to get censured. They don’t usually lose their license, but they get a reprimand or get told that is just not ethical to do.

I think, in the long run, the policy about not treating your family and friends makes sense. The problem is, as is well known from the social sciences and psychology, people get biased when they deal with those they care about, love, and hold close to them.

It’s hard for the doctor to be objective when dealing with people that they really like or love. It’s also difficult for patients because they may not want to bring up something or they are uncomfortable talking with a doctor who’s a family member or close friend. They may not want to complain. They may be a little bit embarrassed about things. It just adds an emotional edge, I think, that’s difficult.

All that said, do I know doctors who regularly prescribe, say, an ointment for something that’s itchy or some kind of a pill when allergy season breaks out? I do. Do I think they’re acting in a horribly unethical manner? I don’t.

You need some judgment here. There are absolutely minor things where objectivity, fear, and anxiety are not in play. You’re going to be able to prescribe the routine thing for the routine itch without worrying too much about whether it’s a stranger, a friend, or your daughter.

What sorts of things am I really talking about when I say that minor variability ought to be allowed? It’s one thing when someone has poison ivy and they’re going to need some kind of standard medicine to treat it. A very different area that’s much more dangerous, and one I would avoid, is in the mental health field, and for that matter, the pain field.

It’s tempting to say: “Oh, my relative is just having a bad time. I’ll give her a little bit of antidepressant medicine,” or “They seem to be having pain after an operation or something, and I’m going to give them a little bit of pain meds just to get them through.”

Those areas are flying red flags. It’s easy to abuse and easy for someone to become a user and manipulate a friend or a doctor who’s a relative into getting things that another doctor wouldn’t be giving. I think that’s the space where you’ve got to exercise extreme caution.

Time and again, when those people get called up in front of the boards for treating relatives, it’s in those spaces of mental health, anxiety, and pain control. Again, when you know that there’s a likelihood of abuse, I think that’s the place where the line has to hold. Don’t treat the relative. Don’t treat the friend.

At the end of the day, I wouldn’t change the AMA policy. I think we should keep it in place and morally try to discourage doctors from caring for those they’re close to or they have emotional ties to.

At the same time, as with all ethical situations, there has to be a little bit of wiggle room for those super-minor cases where it just makes sense to say: “You don’t have to go find somebody else to do this. I can prescribe this ointment or this minor thing for you. No one’s objectivity is going to be soured, and you’re not going to feel in any way at risk because I’m going to prescribe this for you.”

Common sense ought to prevail. The default position is don’t do it; however, maybe with a tiny bit of space for what’s minor, what’s routine, and what really does just save people some inconvenience, there I might just give a little.

Five years have passed since the member states of the World Health Organization (WHO) gathered at the 72nd World Health Assembly and decided that September 17 should be recognized as World Patient Safety Day, acknowledging it as a global health priority.

WHO data indicate the following findings related to medical safety:

• One in 10 patients is harmed while receiving healthcare, and 3 million die as a result.
• More than half of these incidents could be prevented.
• Indirect costs could amount to several billion US dollars annually.

Given the magnitude of preventable harm related to medication use, in 2017, the WHO launched the third Global Patient Safety Challenge: Medication Without Harm with the goal of reducing serious and preventable harm related to medication by 50%. In addition, considering the volume of medication packages prescribed in 2023 by physicians in Spain’s National Health System, it is necessary to understand the most common types of medication errors to provide an effective and efficient response.

According to Spain’s Institute for Safe Medication Practices (ISMP), the 10 types of medication errors detected in 2020 with the most serious consequences were the following:

• Errors due to omission or delay in medication.
• Administration of medication to the wrong patient.
• Errors related to allergies or known adverse effects of medications.
• Dosing errors in pediatric patients.
• Errors due to similarities in the labeling or packaging of marketed medications.
• Errors associated with the lack of use of smart infusion pumps.
• Errors due to accidental administration of neuromuscular blocking agents.
• Incorrect intravenous administration of oral liquid medications.
• Errors in medication reconciliation upon hospital admission and discharge.
• Errors due to patient misunderstandings regarding medication use.

I would like to focus on the fifth item, errors due to similarities in the labeling or packaging of marketed medications.

Medications with similar names or with similar labeling or packaging are known as “look alike–sound alike” medications. They are estimated to account for between 6.2% and 14.7% of all medication errors. Confusion can arise due to spelling and phonetic similarities.

As shown in bulletin no. 50 of the ISMP, difficulties in distinguishing different medications or different presentations of the same medication due to similar packaging and labeling have frequently been associated with reported incidents.

Most cases involve either medications marketed by the same laboratory with a design based on brand image or different medications marketed by different laboratories in screen-printed ampoules used in the same settings.

In 2020, the ISMP published 11 new cases of labeling or packaging that may promote errors on its website. It reported 49 incidents to the Spanish Agency for Medicines and Medical Devices.

Shortages caused by the COVID-19 pandemic have further contributed to these incidents, as healthcare facilities sometimes had to change the medications they usually acquired and purchase whatever was available, without being able to select products that would not be confused with existing medications in the facility.

The ISMP recommends the following general practices for healthcare institutions, professionals, and patients to prevent these errors:

• Develop short lists of easily confused medication names and distribute them among all healthcare professionals.
• Prioritize medication names by active ingredient instead of brand name.
• For similar names, highlight the differences in capital letters, eg, DOBUTamine, DOPamine.
• For similar active ingredients, use brand names.
• Avoid placing similar medications near each other.
• Prescribe all medications electronically to minimize the risk of selecting the wrong medication.
• Make manual prescriptions legible, with clearly written dosages and pharmaceutical forms.
• Encourage patients to actively participate in their treatment and consult a clinician if they have any questions about the medications they are receiving.
• Raise awareness among patients, family members, and caregivers about the issues caused by medication name confusion and inform them about how to avoid these errors.
• Instruct patients to focus on and always use the active ingredient name as an identifying element for the medications they are taking.
• Review treatments with patients to ensure they know the medications they are taking.

A case of locally acquired dengue fever has been confirmed in a resident of Baldwin Park, California, according to a press release from the Los Angeles County Department of Public Health. This locally acquired case of dengue is the third to be reported in California and the first to be reported by the Los Angeles County Department of Public Health; cases were confirmed in Pasadena and Long Beach, California, in the fall of 2023.

“Dengue is the most common insect-borne viral infection in the world, with a wide geographic spread; we know that we have mosquitoes capable of carrying and transmitting the virus in the United States already, and Los Angeles county is a major epicenter for international travel and trade,” James Lawler, MD, associate director for International Programs and Innovation at the Global Center for Health Security and professor in the Infectious Diseases Division at the University of Nebraska Medical Center, Omaha, Nebraska, said in an interview.

Although the patient had no known history of travel to a dengue-endemic area, the potential risk for widespread transmission of the virus in the Los Angeles County area remains low, and no additional suspected cases of locally acquired dengue have been identified, according to the release. However, the recent cases highlight the need for vigilance on the part of the public to reduce transmission of mosquito-borne infections, the public health department noted.

Most cases of dengue occur in people who have traveled to areas where the disease is more common, mainly tropical and subtropical areas, according to the press release. However, the types of mosquitoes that spread dengue exist in parts of the United States, so locally acquired infections can occur.

The Centers for Disease Control and Prevention (CDC) issued an official health advisory in June 2024 about an increased risk for dengue infections in the United States. According to the advisory, 745 cases of dengue were identified in US travelers to endemic areas between January 1, 2024, and June 24, 2024.

The CDC advises clinicians to maintain a high level of suspicion for dengue among individuals with fever and recent travel to areas with frequent dengue transmission, but also to consider locally acquired disease in areas of mosquito vectors.

In clinical practice, dengue may be difficult to differentiate from other febrile systemic infections, Dr. Lawler noted. “Joint pain, low back pain, and headache (often retro-orbital) are common and can be severe, and a rash often appears several days into illness,” he noted.

Do not delay treatment in suspected cases while waiting for test results, the CDC emphasized in the advisory. Food and Drug Administration–approved tests for dengue include RT-PCR and IgM antibody tests or NS1 and IgM antibody tests.

“Severe dengue can be life-threatening and progress to a hemorrhagic fever-like syndrome, and patients with severe dengue should be cared for on a high-acuity or intensive care setting, with close monitoring of labs and fluid status,” Dr. Lawler told this news organization.

The World Health Organization has published guidelines for the management of dengue, which Dr. Lawler strongly recommends to clinicians in the rare event that they are facing a severe case. The treatment for dengue is supportive care, according to the CDC; a vaccine that was deemed safe and effective is no longer being manufactured because of low demand.

Most symptoms last for 2-7 days, and most patients recover within a week, but approximately 1 in 20 may develop severe disease, according to the Los Angeles County Department of Public Health.

Approximately one quarter of dengue infections are symptomatic, and clinicians should know the signs of progression to severe disease, which include abdominal pain or tenderness, persistent vomiting, clinical fluid accumulation, mucosal bleeding, lethargy or restlessness, and liver enlargement, according to the CDC.
 

Local Dengue Not Unexpected

“Sadly, I am not surprised at another locally acquired case of dengue fever in the United States,” said Dr. Lawler. “We also have seen a trend of more historically tropical, insect-borne diseases popping up with locally acquired cases in the United States,” he noted.

Dr. Lawler suggested that “the erosion of state and local public health” is a major contributor to the increase in dengue cases. For more than 100 years, activities of state and local public health officials had significantly curtailed mosquito-borne diseases through aggressive control programs, “but we seem to be losing ground over the last several years,” he said.

“Locally acquired dengue cases are still rare in the United States,” he added. “However, people can protect themselves against dengue and more common arthropod-borne infections by taking precautions to cover up and wear insect repellent while outdoors.”

In addition, the Los Angeles County Department of Public Health emphasized in its press release that local residents reduce their risk for contact with mosquitoes by removing areas of standing water on their property and ensuring well-fitted screens on doors and windows.

Dr. Lawler had no financial conflicts to disclose.

This locally acquired case of dengue is the third to be reported in California and the first to be reported by the Los Angeles County Department of Public Health; cases were confirmed in Pasadena and Long Beach, California, in the fall of 2023.

“Dengue is the most common insect-borne viral infection in the world, with a wide geographic spread; we know that we have mosquitoes capable of carrying and transmitting the virus in the United States already, and Los Angeles county is a major epicenter for international travel and trade,” James Lawler, MD, associate director for International Programs and Innovation at the Global Center for Health Security and professor in the Infectious Diseases Division at the University of Nebraska Medical Center, Omaha, Nebraska, said in an interview.

Although the patient had no known history of travel to a dengue-endemic area, the potential risk for widespread transmission of the virus in the Los Angeles County area remains low, and no additional suspected cases of locally acquired dengue have been identified, according to the release. However, the recent cases highlight the need for vigilance on the part of the public to reduce transmission of mosquito-borne infections, the public health department noted.

Most cases of dengue occur in people who have traveled to areas where the disease is more common, mainly tropical and subtropical areas, according to the press release. However, the types of mosquitoes that spread dengue exist in parts of the United States, so locally acquired infections can occur.

The Centers for Disease Control and Prevention (CDC) issued an official health advisory in June 2024 about an increased risk for dengue infections in the United States. According to the advisory, 745 cases of dengue were identified in US travelers to endemic areas between January 1, 2024, and June 24, 2024.

The CDC advises clinicians to maintain a high level of suspicion for dengue among individuals with fever and recent travel to areas with frequent dengue transmission, but also to consider locally acquired disease in areas of mosquito vectors.

In clinical practice, dengue may be difficult to differentiate from other febrile systemic infections, Dr. Lawler noted. “Joint pain, low back pain, and headache (often retro-orbital) are common and can be severe, and a rash often appears several days into illness,” he noted.

Do not delay treatment in suspected cases while waiting for test results, the CDC emphasized in the advisory. Food and Drug Administration–approved tests for dengue include RT-PCR and IgM antibody tests or NS1 and IgM antibody tests.

“Severe dengue can be life-threatening and progress to a hemorrhagic fever-like syndrome, and patients with severe dengue should be cared for on a high-acuity or intensive care setting, with close monitoring of labs and fluid status,” Dr. Lawler told this news organization.

The World Health Organization has published guidelines for the management of dengue, which Dr. Lawler strongly recommends to clinicians in the rare event that they are facing a severe case. The treatment for dengue is supportive care, according to the CDC; a vaccine that was deemed safe and effective is no longer being manufactured because of low demand.

Most symptoms last for 2-7 days, and most patients recover within a week, but approximately 1 in 20 may develop severe disease, according to the Los Angeles County Department of Public Health.

Approximately one quarter of dengue infections are symptomatic, and clinicians should know the signs of progression to severe disease, which include abdominal pain or tenderness, persistent vomiting, clinical fluid accumulation, mucosal bleeding, lethargy or restlessness, and liver enlargement, according to the CDC.
 

Local Dengue Not Unexpected

“Sadly, I am not surprised at another locally acquired case of dengue fever in the United States,” said Dr. Lawler. “We also have seen a trend of more historically tropical, insect-borne diseases popping up with locally acquired cases in the United States,” he noted.

Dr. Lawler suggested that “the erosion of state and local public health” is a major contributor to the increase in dengue cases. For more than 100 years, activities of state and local public health officials had significantly curtailed mosquito-borne diseases through aggressive control programs, “but we seem to be losing ground over the last several years,” he said.

“Locally acquired dengue cases are still rare in the United States,” he added. “However, people can protect themselves against dengue and more common arthropod-borne infections by taking precautions to cover up and wear insect repellent while outdoors.”

In addition, the Los Angeles County Department of Public Health emphasized in its press release that local residents reduce their risk for contact with mosquitoes by removing areas of standing water on their property and ensuring well-fitted screens on doors and windows.

Dr. Lawler had no financial conflicts to disclose.

The pediatrician’s first patient of the day was a 15-year-old boy complaining of fever, chills, and profound arthralgias. His exam, including a careful assessment of his joints, yielded no clues, and the pediatrician was ready to diagnose this as a routine viral illness. An additional bit of history provided by the patient’s mother prompted the pediatrician to pause and reconsider.

“A week ago, we returned from a visit to Cuba,” the mother reported. “Could this be Oropouche virus infection?”

Travel-associated cases have been reported in the United States. As of September 10, 2024, 52 Oropouche virus disease cases had been reported from five states in the United States. The Centers for Disease Control and Prevention confirmed that the first 31 of these cases were travelers returning from Cuba. The CDC issued a health advisory on August 16, 2024: Increased Oropouche Virus Activity and Associated Risk to Travelers.

The pediatrician quickly reviewed the signs and symptoms of Oropouche virus infection. Disease typically presents as an abrupt onset of fever, severe headache, chills, myalgia, and arthralgia 3 to 10 days after the bite of infected mosquito. Some patients develop a maculopapular rash that starts on the trunk and spreads to the extremities. Meningitis and encephalitis develop in less than 1 in 20 people. The symptoms of Oropouche virus infection overlap with those of other arboviruses such as dengue, chikungunya, and Zika viruses. The disease can also mimic malaria or rickettsial infection. Approximately 60% of people with Oropouche virus infection experience a recurrence of symptoms within days to weeks of the initial resolution of symptoms.

Testing for Oropouche virus infection is available through the CDC’s Arbovirus Diagnostic Laboratory. In people who are acutely ill, reverse transcription-polymerase chain reaction testing can be used to identify the virus in serum and cerebrospinal fluid. Serologic testing is also available for people who have been symptomatic for at least 6 days.

The pediatrician contacted his local health department to discuss the possibility of Oropouche virus infection. After reviewing the case definition, public health authorities recommended laboratory testing for Oropouche virus, dengue, and Zika virus.

Back in the exam room, the pediatrician provided anticipatory guidance to the patient and his mother. There are no antiviral medications to treat Oropouche virus infection, so the pediatrician recommended supportive care, including acetaminophen for fever and pain. He also advised avoiding aspirin or other nonsteroidal anti-inflammatory drugs (NSAIDs) until dengue could be ruled out to reduce the risk of bleeding. After confirming that no one else in the home was sick with similar symptoms, he counseled about prevention strategies.

To date, transmission of Oropouche virus in the United States has not been documented, but vectors potentially capable of transmitting the virus are present in some areas of the United States. When people who are infected with Oropouche are bitten, they can spread the virus through their blood to biting midges or mosquitoes. The insects can then spread the virus to other people. To reduce to potential for local transmission, people who are sick with suspected Oropouche virus infection are advised to avoid biting-midge and mosquito bites for the first week of their illness. Any person who has recently traveled to an area where Oropouche virus transmission is occurring should also avoid insect bites for 3 weeks after returning home to account for the potential incubation period of the virus. This includes wearing an EPA-registered insect repellent.
 

A suspect case is a patient who has been in an area with documented or suspected OROV circulation* within 2 weeks of initial symptom onset (as patients may experience recurrent symptoms) and the following:

• Abrupt onset of reported fever, headache, and one or more of the following: myalgia, arthralgia, photophobia, retro-orbital/eye pain, or signs and symptoms of neuroinvasive disease (eg, stiff neck, altered mental status, seizures, limb weakness, or cerebrospinal fluid pleocytosis).
• Tested negative for other possible diseases, in particular dengue.†
• Absence of a more likely clinical explanation.

*If concern exists for local transmission in a nonendemic area, consider if the patient shared an exposure location with a person with confirmed OROV infection, lives in an area where travel-related cases have been identified, or has known vector exposure (eg, mosquitoes or biting midges).

†If strong suspicion of OROV disease exists based on the patient’s clinical features and history of travel to an area with virus circulation, do not wait on negative testing before sending specimens to CDC.

Peering through his microscope in 1910, Franco-Canadian microbiologist Félix d’Hérelle noticed some “clear spots” in his bacterial cultures, an anomaly that turned out to be viruses preying on the bacteria. Years later, Mr. d’Hérelle would come to use these viruses, which he called bacteriophages, to treat patients plagued with dysentery after World War I.

In the decades that followed, Mr. d’Hérelle and others used this phage therapy to treat bubonic plague and other bacterial infections until the technique fell into disuse after the widespread adoption of antibiotics in the 1940s.

But now, with bacteria evolving resistance to more and more antibiotics, phage therapy is drawing a second look from researchers — sometimes with a novel twist. Instead of simply using the phages to kill bacteria directly, the new strategy aims to catch the bacteria in an evolutionary dilemma — one in which they cannot evade phages and antibiotics simultaneously.

This plan, which uses something called “phage steering,” has shown promising results in initial tests, but the scope of its usefulness remains to be proven.

There’s certainly need to find new ways to respond to bacterial infections. More than 70% of hospital-acquired bacterial infections in the United States are resistant to at least one type of antibiotic. And some pathogens, such as Acinetobacter, Pseudomonas, Escherichia coli, and Klebsiella — classified by the World Health Organization as some of the biggest threats to human health — are resistant to multiple antibiotics. In 2019, antibacterial resistance was linked to 4.95 million deaths globally, heightening the call for more effective treatment options.

One of the ways that bacteria can evolve resistance to antibiotics is by using structures in their membranes that are designed to move unwanted molecules out of the cell. By modifying these “efflux pumps” to recognize the antibiotic, bacteria can eliminate the drug before it poisons them.

As it turns out, some phages appear to use these same efflux pumps to invade the bacterial cell. The phage presumably attaches its tail to the outer portion of the pump protein, like a key slipping into a lock, and then injects its genetic material into the cell. This lucky coincidence led Paul Turner, PhD, an evolutionary biologist at Yale University, New Haven, Connecticut, to suggest that treating a patient with phages and antibiotics simultaneously could trap bacteria in a no-win situation: If they evolve to modify their efflux pumps so the phage can’t bind, the pumps will no longer expel antibiotics, and the bacteria will lose their resistance. But if they retain their antibiotic resistance, the phages will kill them, as Dr. Turner and colleagues explained in the 2023 Annual Review of Virology.

The result, in other words, is a two-pronged attack, said Michael Hochberg, PhD, an evolutionary biologist at the French National Centre for Scientific Research who studies how to prevent the evolution of bacterial resistance. “It’s kind of like a crisscross effect.” The same principle can target other bacterial molecules that play a dual role in resistance to viruses and antibiotics.

Turner tested this hypothesis on multidrug-resistant Pseudomonas aeruginosa, which causes dangerous infections, especially in healthcare settings. This bacterium has four efflux pumps involved in antibiotic resistance, and Dr. Turner predicted that if he could find a phage that used one of the pumps as a way into the cell, the bacterium would be forced to slam the door on the phage by mutating the receptor — thereby impeding its ability to pump out antibiotics.

Sampling from the environment, Dr. Turner’s team collected 42 phage strains that infect P aeruginosa. Out of all the phages, one, OMKO1, bound to an efflux pump, making it the perfect candidate for the experiment.

The researchers then cultured antibiotic-resistant P aeruginosa together with OMKO1, hoping this would force the bacterium to modify its efflux pump to resist the phage. They exposed these phage-resistant bacteria, as well as their normal, phage-sensitive counterparts, to four antibiotics the bacteria had been resistant to: tetracycline, erythromycin, ciprofloxacin, and ceftazidime.

As the theory predicted, the bacteria that had evolved resistance to the phage were more sensitive to the antibiotics than those that had not been exposed to the phage. This suggests that the bacteria had, indeed, been forced to lose their antibiotic resistance through their need to fight off the phage.

Other researchers have also shown that phage steering can resensitize bacteria to common antibiotics they’d become resistant to. One study, by an international research team, showed that a phage called Phab24 can be used to restore sensitivity to the antibiotic colistin in Acinetobacter baumannii, which causes life-threatening diseases.

In a second study, researchers at Monash University in Australia sampled infectious bacteria from patients. They found that several phages, including strains known as phi-FG02 and phi-CO01, were already present in some of the samples, and that A baumannii bacteria exposed to the phages had inactivated a gene that helps create the microbe’s important outer layer, or capsule. This layer serves as the entry point for the phages, but it also helps the bacterium to form biofilms that keep out antibiotics — so removing the layer rendered A baumannii susceptible to several antibiotics that it was previously resistant to.

In a third study, researchers from the University of Liverpool discovered that, when a P aeruginosa strain that was resistant to all antibiotics was exposed to phages, the bacterium became sensitive to two antibiotics that were otherwise considered ineffective against P aeruginosa.

Dr. Turner’s team has used phage steering in dozens of cases of personalized therapy in clinical settings, said Benjamin Chan, PhD, a microbiologist at Yale University who works with Dr. Turner. The results, many still unpublished, have been promising so far. Nonrespiratory infections are relatively easy to clear off, and lung infections, which the phage steering approach wouldn’t be expected to eradicate completely, often show some improvement.

“I would say that we have been quite successful in using phage steering to treat difficult-to-manage infections, reducing antimicrobial resistance in many cases,” he said. But he notes that it is sometimes difficult to determine whether phage steering really was responsible for the cures.
 

Devil in the details

Phage therapy may not work for all antibiotic-resistant bacteria, said molecular biologist Graham Hatfull, PhD, of the University of Pittsburgh in Pennsylvania. That’s because phages are very host specific, and for most phages, no one knows what target they bind to on the bacterial cell surface. For phage steering to work against antibiotic resistance, the phage has to bind to a molecule that’s involved in that resistance — and it’s not clear how often that fortuitous coincidence occurs.

Jason Gill, PhD, who studies bacteriophage biology at Texas A&M University, College Station, said that it is not easy to predict if a phage will induce antibiotic sensitivity. So you always have to hunt for the right virus each time.

Dr. Gill knows from experience how complicated the approach can get. He was part of a team of researchers and doctors who used phages to treat a patient with a multidrug-resistant A baumannii infection. Less than 4 days after the team administered phages intravenously and through the skin, the patient woke up from a coma and became responsive to the previously ineffective antibiotic minocycline — a striking success.

But when Dr. Gill tried a similar experiment in cell cultures, he got a different result. The A baumannii developed resistance to the phages, but they also maintained their resistance to minocycline. “There’s not a complete mechanistic understanding,” said Dr. Gill. “The linkage between phage resistance and antibiotic sensitivity probably varies by bacterial strain, phage and antibiotic.” That means phage steering may not always work.

Dr. Turner, for his part, pointed out another potential problem: That phages could work too well. If phage therapy kills large amounts of bacteria and deposits their remains in the bloodstream quickly, for example, this could trigger septic shock in patients. Scientists do not yet know how to address this problem.

Another concern is that doctors have less precise control over phages than antibiotics. “Phages can mutate, they can adapt, they have a genome,” said Dr. Hochberg. Safety concerns, he notes, are one factor inhibiting the routine use of phage therapy in countries like the United States, restricting it to case-by-case applications such as Dr. Turner and Dr. Chan’s.

Phage therapy may have been too high-tech for the 1940s, and even today, scientists grapple with how to use it. What we need now, said Dr. Turner, are rigorous experiments that will teach us how to make it work.

And some pathogens, such as Acinetobacter, Pseudomonas, Escherichia coli, and Klebsiella — classified by the World Health Organization as some of the biggest threats to human health — are resistant to multiple antibiotics. In 2019, antibacterial resistance was linked to 4.95 million deaths globally, heightening the call for more effective treatment options.

One of the ways that bacteria can evolve resistance to antibiotics is by using structures in their membranes that are designed to move unwanted molecules out of the cell. By modifying these “efflux pumps” to recognize the antibiotic, bacteria can eliminate the drug before it poisons them.

As it turns out, some phages appear to use these same efflux pumps to invade the bacterial cell. The phage presumably attaches its tail to the outer portion of the pump protein, like a key slipping into a lock, and then injects its genetic material into the cell. This lucky coincidence led Paul Turner, PhD, an evolutionary biologist at Yale University, New Haven, Connecticut, to suggest that treating a patient with phages and antibiotics simultaneously could trap bacteria in a no-win situation: If they evolve to modify their efflux pumps so the phage can’t bind, the pumps will no longer expel antibiotics, and the bacteria will lose their resistance. But if they retain their antibiotic resistance, the phages will kill them, as Dr. Turner and colleagues explained in the 2023 Annual Review of Virology.

The result, in other words, is a two-pronged attack, said Michael Hochberg, PhD, an evolutionary biologist at the French National Centre for Scientific Research who studies how to prevent the evolution of bacterial resistance. “It’s kind of like a crisscross effect.” The same principle can target other bacterial molecules that play a dual role in resistance to viruses and antibiotics.

Turner tested this hypothesis on multidrug-resistant Pseudomonas aeruginosa, which causes dangerous infections, especially in healthcare settings. This bacterium has four efflux pumps involved in antibiotic resistance, and Dr. Turner predicted that if he could find a phage that used one of the pumps as a way into the cell, the bacterium would be forced to slam the door on the phage by mutating the receptor — thereby impeding its ability to pump out antibiotics.

Sampling from the environment, Dr. Turner’s team collected 42 phage strains that infect P aeruginosa. Out of all the phages, one, OMKO1, bound to an efflux pump, making it the perfect candidate for the experiment.

The researchers then cultured antibiotic-resistant P aeruginosa together with OMKO1, hoping this would force the bacterium to modify its efflux pump to resist the phage. They exposed these phage-resistant bacteria, as well as their normal, phage-sensitive counterparts, to four antibiotics the bacteria had been resistant to: tetracycline, erythromycin, ciprofloxacin, and ceftazidime.

As the theory predicted, the bacteria that had evolved resistance to the phage were more sensitive to the antibiotics than those that had not been exposed to the phage. This suggests that the bacteria had, indeed, been forced to lose their antibiotic resistance through their need to fight off the phage.

Other researchers have also shown that phage steering can resensitize bacteria to common antibiotics they’d become resistant to. One study, by an international research team, showed that a phage called Phab24 can be used to restore sensitivity to the antibiotic colistin in Acinetobacter baumannii, which causes life-threatening diseases.

In a second study, researchers at Monash University in Australia sampled infectious bacteria from patients. They found that several phages, including strains known as phi-FG02 and phi-CO01, were already present in some of the samples, and that A baumannii bacteria exposed to the phages had inactivated a gene that helps create the microbe’s important outer layer, or capsule. This layer serves as the entry point for the phages, but it also helps the bacterium to form biofilms that keep out antibiotics — so removing the layer rendered A baumannii susceptible to several antibiotics that it was previously resistant to.

In a third study, researchers from the University of Liverpool discovered that, when a P aeruginosa strain that was resistant to all antibiotics was exposed to phages, the bacterium became sensitive to two antibiotics that were otherwise considered ineffective against P aeruginosa.

Dr. Turner’s team has used phage steering in dozens of cases of personalized therapy in clinical settings, said Benjamin Chan, PhD, a microbiologist at Yale University who works with Dr. Turner. The results, many still unpublished, have been promising so far. Nonrespiratory infections are relatively easy to clear off, and lung infections, which the phage steering approach wouldn’t be expected to eradicate completely, often show some improvement.

“I would say that we have been quite successful in using phage steering to treat difficult-to-manage infections, reducing antimicrobial resistance in many cases,” he said. But he notes that it is sometimes difficult to determine whether phage steering really was responsible for the cures.
 

Devil in the details

Phage therapy may not work for all antibiotic-resistant bacteria, said molecular biologist Graham Hatfull, PhD, of the University of Pittsburgh in Pennsylvania. That’s because phages are very host specific, and for most phages, no one knows what target they bind to on the bacterial cell surface. For phage steering to work against antibiotic resistance, the phage has to bind to a molecule that’s involved in that resistance — and it’s not clear how often that fortuitous coincidence occurs.

Jason Gill, PhD, who studies bacteriophage biology at Texas A&M University, College Station, said that it is not easy to predict if a phage will induce antibiotic sensitivity. So you always have to hunt for the right virus each time.

Dr. Gill knows from experience how complicated the approach can get. He was part of a team of researchers and doctors who used phages to treat a patient with a multidrug-resistant A baumannii infection. Less than 4 days after the team administered phages intravenously and through the skin, the patient woke up from a coma and became responsive to the previously ineffective antibiotic minocycline — a striking success.

But when Dr. Gill tried a similar experiment in cell cultures, he got a different result. The A baumannii developed resistance to the phages, but they also maintained their resistance to minocycline. “There’s not a complete mechanistic understanding,” said Dr. Gill. “The linkage between phage resistance and antibiotic sensitivity probably varies by bacterial strain, phage and antibiotic.” That means phage steering may not always work.

Dr. Turner, for his part, pointed out another potential problem: That phages could work too well. If phage therapy kills large amounts of bacteria and deposits their remains in the bloodstream quickly, for example, this could trigger septic shock in patients. Scientists do not yet know how to address this problem.

Another concern is that doctors have less precise control over phages than antibiotics. “Phages can mutate, they can adapt, they have a genome,” said Dr. Hochberg. Safety concerns, he notes, are one factor inhibiting the routine use of phage therapy in countries like the United States, restricting it to case-by-case applications such as Dr. Turner and Dr. Chan’s.

Phage therapy may have been too high-tech for the 1940s, and even today, scientists grapple with how to use it. What we need now, said Dr. Turner, are rigorous experiments that will teach us how to make it work.

Peering through his microscope in 1910, Franco-Canadian microbiologist Félix d’Hérelle noticed some “clear spots” in his bacterial cultures, an anomaly that turned out to be viruses preying on the bacteria. Years later, Mr. d’Hérelle would come to use these viruses, which he called bacteriophages, to treat patients plagued with dysentery after World War I.

In the decades that followed, Mr. d’Hérelle and others used this phage therapy to treat bubonic plague and other bacterial infections until the technique fell into disuse after the widespread adoption of antibiotics in the 1940s.

But now, with bacteria evolving resistance to more and more antibiotics, phage therapy is drawing a second look from researchers — sometimes with a novel twist. Instead of simply using the phages to kill bacteria directly, the new strategy aims to catch the bacteria in an evolutionary dilemma — one in which they cannot evade phages and antibiotics simultaneously.

This plan, which uses something called “phage steering,” has shown promising results in initial tests, but the scope of its usefulness remains to be proven.

There’s certainly need to find new ways to respond to bacterial infections. More than 70% of hospital-acquired bacterial infections in the United States are resistant to at least one type of antibiotic.

The University of Virginia (UVA) is defending the CEO of its health system and its medical school dean in the wake of a very public call for their removal.

At least 128 members of the University of Virginia faculty who are employed by both the medical school and the UVA Physicians Group wrote to the UVA Board of Visitors and its peer-elected faculty leaders, expressing no confidence in K. Craig Kent, MD, CEO of UVA Health and executive vice president for health affairs, and Melina Kibbe, MD, dean of the medical school and chief health affairs officer.

Dr. Kibbe, a vascular surgeon and researcher, is also the editor in chief of JAMA Surgery.

“We call for the immediate removal of Craig Kent and Melina Kibbe,” wrote the physicians.

The letter alleged that patient safety was compromised because doctors, nurses, and other staff were pressured to abstain from reporting safety concerns and that physicians had been hired “despite concerns regarding integrity and quality.” Those who raised safety concerns faced “explicit and implicit threats and retaliation,” including delays and denials of promotion and tenure, said the letter.

The September 5 letter did not include signatures. The authors said that names were being protected, but that they would share the names with a limited audience.

UVA President Jim Ryan took issue with the notion that the signees were anonymous. He said in his own letter to medical school faculty that some of the accusations were about matters that had already been addressed or that were being worked on. As far as allegations that he was not previously aware of, “we will do our best to investigate,” he said.

The faculty who signed the letter “have besmirched the reputations of not just Melina and Craig,” wrote Mr. Ryan. “They have unfairly — and I trust unwittingly — cast a shadow over the great work of the entire health system and medical school.”

The authors claimed that reports about bullying and harassment of trainees had been “suppressed, minimized, and subsequently altered.”

And they said that spending on leadership was prioritized over addressing clinical and technical staff shortages. Whistleblowers who reported fraud were not protected, and clinicians were pressured to modify patient records to “obfuscate adverse outcomes and boost productivity metrics,” they wrote.

The 128 members of the UVA Physicians Group who signed the letter represent about 10% of the 1400 medical school faculty members.

It is not the first time that Dr. Kent has been given a vote of no confidence. In 2017, when he was the dean of the College of Medicine at the Ohio State University, Dr. Kent was accused in a “no confidence” letter from 25 physicians and faculty of helping to undermine the school’s mission and taking actions that led to resignations and early retirements of many staff, the Columbus Dispatch reported.

William G. Crutchfield Jr., a member of the UVA Health System Board, defended Dr. Kent and Dr. Kibbe in a lengthy statement shared with this news organization. He said that UVA Health’s four hospitals had received “A” ratings for safety, and that the system has a 5.1% turnover rate compared with a national average of 8.3%.

Dr. Kent and Dr. Kibbe have recruited faculty from top academic medical centers, Mr. Crutchfield wrote.

“If our work environment were so toxic, these people would not have joined our faculty,” he wrote.

Mr. Crutchfield credited Dr. Kent and Dr. Kibbe with crafting a new 10-year strategic plan and for hiring a chief strategy officer to lead the plan — a move that replaced “expensive outside consultants.”

Mr. Ryan said in his letter that his inbox “is overflowing with testimonials from some of the 1200-plus faculty who did not sign the letter, who attest that the health system today — under Melina and Craig’s leadership — is in the best shape it has ever been in, and that they have addressed changes that have needed to be made for more than two decades.”

A request to see some of these positive testimonials was not answered by press time.

Mr. Crutchfield, like Mr. Ryan, said that the letter writers were doing more harm than good.

“If a small cabal of people hiding behind anonymity can force outstanding leaders out of UVA, it will make it extremely difficult to recruit outstanding new physicians, nurses, technicians, and administrators,” he wrote.

New COVID-19 vaccines formulated for better protection against the currently circulating variants have been approved by the US Food and Drug Administration.

The COVID vaccines available this fall have been updated to better match the currently circulating COVID strains, said William Schaffner, MD, professor of medicine in the Division of Infectious Diseases at Vanderbilt University, Nashville, Tennessee, in an interview.

“The Pfizer and Moderna vaccines — both mRNA vaccines — target the KP.2 variant, while the Novavax vaccine targets the JN.1 variant, which is a predecessor to KP.2,” said Dr. Schaffner, who also serves as a spokesperson for the National Foundation for Infectious Diseases. “The Novavax vaccine is a protein adjuvant vaccine made in a more traditional fashion and may appeal to those who remain hesitant about receiving an mRNA vaccine,” he explained. However, all three vaccines are designed to protect against severe COVID illness and reduce the likelihood of hospitalization, he said.
 

Who Needs It?

“The CDC’s Advisory Committee on Immunization Practices (ACIP) continues to recommend that everyone in the United States who is age 6 months and older receive the updated COVID vaccine this fall, along with influenza vaccine,” Dr. Schaffner said.

“This was not a surprise because COVID will produce a sizable winter outbreak,” he predicted. Although older people and those who have chronic medical conditions such as heart or lung disease, diabetes, or other immunocompromising conditions suffer the most serious impact of COVID, he said. “The virus can strike anyone, even the young and healthy.” The risk for long COVID persists as well, he pointed out.

The ACIP recommendation is endorsed by the American Academy of Pediatrics and other professional organizations, Dr. Shaffner said.

A frequently asked question is whether the COVID and flu vaccines can be given at the same time, and the answer is yes, according to a statement from the Centers for Disease Control and Prevention (CDC).

“The optimal time to be vaccinated is late September and anytime during October in order to get the benefit of protection through the winter,” Dr. Schaffner said.

As with earlier versions of the COVID-19 vaccine, side effects vary from person to person. Reported side effects of the updated vaccine are similar to those seen with earlier versions and may include injection site pain, redness and swelling, fatigue, headache, muscle pain, chills, nausea, and fever, but most of these are short-lived, according to the CDC.
 

Clinical Guidance

The CDC’s clinical guidance for COVID-19 vaccination outlines more specific guidance for vaccination based on age, vaccination history, and immunocompromised status and will be updated as needed.

A notable difference in the latest guidance is the recommendation of only one shot for adults aged 65 years and older who are NOT moderately or severely immunocompromised. For those who are moderately or severely immunocompromised, the CDC recommends two to three doses of the same brand of vaccine.

Dr. Schaffner strongly encouraged clinicians to recommend the COVID-19 vaccination for all eligible patients. “COVID is a nasty virus that can cause serious disease in anyone,” and protection from previous vaccination or prior infection has likely waned, he said.

Dr. Schaffner also encouraged healthcare professionals and their families to lead by example. “We should all be vaccinated and let our patients know that we are vaccinated and that we want all our patents to be protected,” he said.

The updated COVID-19 vaccination recommendations have become much simpler for clinicians and patients, with a single messenger RNA (mRNA) vaccine required for anyone older than 5 years, said David J. Cennimo, MD, associate professor of medicine and pediatrics in the Division of Infectious Disease at Rutgers New Jersey Medical School, Newark, New Jersey, in an interview.

“The recommendations are a bit more complex for children under 5 years old receiving their first vaccination; they require two to three doses depending on the brand,” he said. “It is important to review the latest recommendations to plan the doses with the correct interval timing. Considering the doses may be 3-4 weeks apart, start early,” he advised.
 

One-Time Dosing

Although the updated mRNA vaccine is currently recommended as a one-time dose, Dr. Cennimo said he can envision a scenario later in the season when a second dose is recommended for the elderly and those at high risk for severe illness. Dr. Cennimo said that he strongly agrees with the recommendations that everyone aged 6 months and older receive an updated COVID-19 vaccine. Older age remains the prime risk factor, but anyone can become infected, he said.

Predicting a prime time to get vaccinated is tricky because no one knows when the expected rise in winter cases will occur, said Dr. Cennimo.

“We know from years of flu vaccine data that some number of people who delay the vaccine will never return and will miss protection,” he said. Therefore, delaying vaccination is not recommended. Dr. Cennimo plans to follow his habit of getting vaccinated in early October. “I anticipate the maximal effectiveness of the vaccine will carry me through the winter,” he said.

Data support the safety and effectiveness for both flu and COVID vaccines if they are given together, and some research on earlier versions of COVID vaccines suggested that receiving flu and COVID vaccines together might increase the antibody response against COVID, but similar studies of the updated version have not been done, Dr. Cennimo said.

Clinicians may have to overcome the barrier of COVID fatigue to encourage vaccination, Dr. Cennimo said. Many people say they “want it to be over,” he said, but SARS-CoV-2, established as a viral respiratory infection, shows no signs of disappearing. In addition, new data continue to show higher mortality associated with COVID-19 than with influenza, he said.

“We need to explain to our patients that COVID-19 is still here and is still dangerous. The yearly influenza vaccination campaigns should have established and normalized the idea of an updated vaccine targeted for the season’s predicated strains is expected,” he emphasized. “We now have years of safety data behind these vaccines, and we need to make a strong recommendation for this protection,” he said.

COVID-19 vaccines are covered by private insurance, as well as by Medicare and Medicaid, according to the CDC. Vaccination for uninsured children is covered through the Vaccines for Children Program.

“The Pfizer and Moderna vaccines — both mRNA vaccines — target the KP.2 variant, while the Novavax vaccine targets the JN.1 variant, which is a predecessor to KP.2,” said Dr. Schaffner, who also serves as a spokesperson for the National Foundation for Infectious Diseases. “The Novavax vaccine is a protein adjuvant vaccine made in a more traditional fashion and may appeal to those who remain hesitant about receiving an mRNA vaccine,” he explained. However, all three vaccines are designed to protect against severe COVID illness and reduce the likelihood of hospitalization, he said.
 

Who Needs It?

“The CDC’s Advisory Committee on Immunization Practices (ACIP) continues to recommend that everyone in the United States who is age 6 months and older receive the updated COVID vaccine this fall, along with influenza vaccine,” Dr. Schaffner said.

“This was not a surprise because COVID will produce a sizable winter outbreak,” he predicted. Although older people and those who have chronic medical conditions such as heart or lung disease, diabetes, or other immunocompromising conditions suffer the most serious impact of COVID, he said. “The virus can strike anyone, even the young and healthy.” The risk for long COVID persists as well, he pointed out.

The ACIP recommendation is endorsed by the American Academy of Pediatrics and other professional organizations, Dr. Shaffner said.

A frequently asked question is whether the COVID and flu vaccines can be given at the same time, and the answer is yes, according to a statement from the Centers for Disease Control and Prevention (CDC).

“The optimal time to be vaccinated is late September and anytime during October in order to get the benefit of protection through the winter,” Dr. Schaffner said.

As with earlier versions of the COVID-19 vaccine, side effects vary from person to person. Reported side effects of the updated vaccine are similar to those seen with earlier versions and may include injection site pain, redness and swelling, fatigue, headache, muscle pain, chills, nausea, and fever, but most of these are short-lived, according to the CDC.
 

Clinical Guidance

The CDC’s clinical guidance for COVID-19 vaccination outlines more specific guidance for vaccination based on age, vaccination history, and immunocompromised status and will be updated as needed.

A notable difference in the latest guidance is the recommendation of only one shot for adults aged 65 years and older who are NOT moderately or severely immunocompromised. For those who are moderately or severely immunocompromised, the CDC recommends two to three doses of the same brand of vaccine.

Dr. Schaffner strongly encouraged clinicians to recommend the COVID-19 vaccination for all eligible patients. “COVID is a nasty virus that can cause serious disease in anyone,” and protection from previous vaccination or prior infection has likely waned, he said.

Dr. Schaffner also encouraged healthcare professionals and their families to lead by example. “We should all be vaccinated and let our patients know that we are vaccinated and that we want all our patents to be protected,” he said.

The updated COVID-19 vaccination recommendations have become much simpler for clinicians and patients, with a single messenger RNA (mRNA) vaccine required for anyone older than 5 years, said David J. Cennimo, MD, associate professor of medicine and pediatrics in the Division of Infectious Disease at Rutgers New Jersey Medical School, Newark, New Jersey, in an interview.

“The recommendations are a bit more complex for children under 5 years old receiving their first vaccination; they require two to three doses depending on the brand,” he said. “It is important to review the latest recommendations to plan the doses with the correct interval timing. Considering the doses may be 3-4 weeks apart, start early,” he advised.
 

One-Time Dosing

Although the updated mRNA vaccine is currently recommended as a one-time dose, Dr. Cennimo said he can envision a scenario later in the season when a second dose is recommended for the elderly and those at high risk for severe illness. Dr. Cennimo said that he strongly agrees with the recommendations that everyone aged 6 months and older receive an updated COVID-19 vaccine. Older age remains the prime risk factor, but anyone can become infected, he said.

Predicting a prime time to get vaccinated is tricky because no one knows when the expected rise in winter cases will occur, said Dr. Cennimo.

“We know from years of flu vaccine data that some number of people who delay the vaccine will never return and will miss protection,” he said. Therefore, delaying vaccination is not recommended. Dr. Cennimo plans to follow his habit of getting vaccinated in early October. “I anticipate the maximal effectiveness of the vaccine will carry me through the winter,” he said.

Data support the safety and effectiveness for both flu and COVID vaccines if they are given together, and some research on earlier versions of COVID vaccines suggested that receiving flu and COVID vaccines together might increase the antibody response against COVID, but similar studies of the updated version have not been done, Dr. Cennimo said.

Clinicians may have to overcome the barrier of COVID fatigue to encourage vaccination, Dr. Cennimo said. Many people say they “want it to be over,” he said, but SARS-CoV-2, established as a viral respiratory infection, shows no signs of disappearing. In addition, new data continue to show higher mortality associated with COVID-19 than with influenza, he said.

“We need to explain to our patients that COVID-19 is still here and is still dangerous. The yearly influenza vaccination campaigns should have established and normalized the idea of an updated vaccine targeted for the season’s predicated strains is expected,” he emphasized. “We now have years of safety data behind these vaccines, and we need to make a strong recommendation for this protection,” he said.

COVID-19 vaccines are covered by private insurance, as well as by Medicare and Medicaid, according to the CDC. Vaccination for uninsured children is covered through the Vaccines for Children Program.
