Flu Updates

Weekly U.S. Influenza Surveillance Report Updated 1/13/23

Current U.S. Surveillance Report

  • Seasonal influenza activity continues but is declining in most areas.
  • Of influenza A viruses detected and subtyped during week 1, 72% were influenza A(H3N2) and 28% were influenza A(H1N1).
  • Five influenza-associated pediatric deaths were reported this week, for a total of 79 pediatric flu deaths reported so far this season.
  • CDC estimates that, so far this season, there have been at least 24 million illnesses, 260,000 hospitalizations, and 16,000 deaths from flu.
  • The cumulative hospitalization rate in the FluSurv-NET system was 1.8 times higher than the highest cumulative in-season hospitalization rate observed for week 1 during previous seasons going back to 2010-2011. However, this in-season rate is still lower than end-of-season hospitalization rates for all but 4 pre-COVID-19-pandemic seasons going back to 2010-2011.
  • The number of flu hospital admissions reported in the HHS Protect system decreased compared to week 52.
  • The majority of influenza viruses tested are in the same genetic subclade as and antigenically similar to the influenza viruses included in this season’s influenza vaccine.
  • All viruses collected and evaluated this season have been susceptible to the influenza antivirals oseltamivir, peramivir, zanamivir, and baloxavir.
  • An annual flu vaccine is the best way to protect against flu. Vaccination helps prevent infection and can also prevent serious outcomes in people who get vaccinated but still get sick with flu.
  • CDC continues to recommend that everyone ages 6 months and older get an annual flu vaccine as long as flu activity continues.

CDC Influenza Like Illness Activity Level Indicator

Levels of influenza activity are determined by reports to ILINet, this system monitors outpatient visits for Influenza Like Illness (fever and cough or sore throat), not laboratory confirmed influenza. The map reflects the intensity of ILI activity, not the extent of geographic spread of flu within a jurisdiction. Additional information about the ILINet system can be found here.
