The 2015-2016 seasonal influenza virus has gotten hold of New Jersey and just won’t let go, according to the latest data from the Centers for Disease Control and Prevention.
For the week ending April 23, 2016, influenza-like illness (ILI) activity in the United States remained at level 10 on the CDC’s 1-10 scale for the 11th consecutive week, even as the country’s overall proportion of outpatient visits for ILI dropped to 2.0%, which is below the national baseline of 2.1%, the CDC reported.
Two other states – Arizona and Arkansas – joined New Jersey in bucking the trend of decreasing ILI activity, as both moved up to level 7 and the high end of the “moderate” range. Arizona had been at level 5 the week before, while Arkansas was at level 4. No other state was above level 5 for the most recent week, and 27 states were at level 1, data from the CDC’s Influenza-like Illness Surveillance Network (ILINet) show.
Four flu-related pediatric deaths were reported during the week ending April 23, only one of which occurred that week. The total number of pediatric deaths rose to 60 for the 2015-2016 season, with 27 states and Puerto Rico reporting deaths so far, the CDC noted.
The CDC also reported a cumulative influenza-associated hospitalization rate for the season of 29.8 such hospitalizations per 100,000 population. This data was based on 8,239 laboratory-confirmed influenza-associated hospitalizations reported between October 1, 2015 and April 23, 2016. The highest rate of hospitalization was among adults aged 65 years or older (79.6 per 100,000 population), followed by adults aged 50-64 (43.1 per 100,000 population) and children aged 0-4 years (40.5 per 100,000 population). Among all hospitalizations, 6,254 (75.9%) were associated with influenza A, 1,905 (23.1%) with influenza B, 41 (0.5%) with influenza A and B co-infection, and 39 (0.5%) had no virus type information.
