Influenza Update Week Ending 1-20-2018
Week ending 1-20-18 TThe CDC reported that influenza (Flu) activity, including diagnosed flu and Influenza-Like-Illness (ILI), increased again. All states reported widespread flu activity except for Hawaii, and ILI levels also increased. This indicates that this flu season is a severe one – at, or just below — the data seen in the most recent highly severe flu season of 2014-15. Deaths associated with flu have reached system-specific epidemic thresholds.
The dominating flu subtype remained A H3N2, which is typically a more severe subtype of flu with increased complication rates.
Although the highest risk for complications & hospitalizations remained in those 65 years or older, other age groups, ages 50-64 and in young children ages 0-4, also had higher rates of complications and hospitalizations.
