Health authorities in Wuhan, Hubei Province, China, identified the novel coronavirus, 2019-nCoV, responsible for the outbreak of a mysterious pneumonia that resulted in hospitalization of more than 40 patients and one death, according to the Centers for Disease Control and Prevention in a statement on the CDC website.
On Jan. 13, the Thailand’s Ministry of Public Health reported the first imported case of lab-confirmed 2019-nCoV from Wuhan. The Centers for Disease Control and Prevention stated: “The traveler with febrile illness was detected on the same day by thermal surveillance at Suvarnabhumi Airport, Thailand, and was hospitalized the same day. After temperature check and initial assessment, she was transferred to the hospital for further investigations and treatment.”
Samples from this patient tested positive for coronaviruses by reverse transcriptase-polymerase chain reaction. The genomic sequencing analysis was performed by Emerging Infectious Diseases Health Science Center, the Thai Red Cross Society, and the Thai National Institute of Health. The patient is reported to be in stable condition.
The New York Times has reported a case of 2019-nCoV in Japan in a traveler returning from Wuhan. That patient is reported to have recovered and been discharged.
Chinese health authorities transmitted the full genome of “2019 novel coronavirus,” or “2019-nCoV,” to GenBank, the genetic sequence database managed by the National Institutes of Health, and in the Global Initiative on Sharing All Influenza Data portal.
Coronaviruses are a large family of viruses. Most known human coronaviruses only cause mild respiratory disease, such as the common cold. But several coronaviruses have emerged to infect people and cause severe disease, such as has been seen with severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS). The cases in the Wuhan pneumonia outbreak have tested negative for both SARS and MERS.
The outbreak in Wuhan appears to be contained. The World Health Organization reported that the Wuhan health authorities identified and followed 763 close contacts, including health care workers. No additional cases of infection with the novel coronavirus have been identified. The cluster of cases is linked to the Wuhan South China Seafood City market where – in addition to seafood – chickens, bats, marmots, and other animals were sold. That market has been closed since Jan. 1, 2020, for cleaning and disinfection.
The WHO is monitoring the situation closely and is in close contact with Chinese health authorities.
The CDC has issued a Level 1 travel alert and recommended that travelers to Wuhan, a city of over 19 million people, avoid animal and meat markets, avoid contact with sick people, and wash hands often with soap and water. Travelers who have been in Wuhan recently and who experience respiratory symptoms should notify the local health department immediately.
In addition, the CDC recommends that, for symptomatic patients with a history of travel to Wuhan, caution should be exercised in the health care setting. “Ask such patients to don a surgical mask as soon as they are identified. Conduct their evaluation in a private room with the door closed. Personnel entering the room to evaluate the patient should use contact precautions and wear an N95 disposable facepiece respirator. For patients admitted for inpatient care, implement contact and airborne isolation precautions, in addition to standard precautions, until further information becomes available.
