Flu activity is still elevated in the United States but is declining. It is possible, however, that flu activity will continue for several weeks in parts of the country.
While H3N2 viruses predominated earlier in the season, influenza B viruses have been more common in recent weeks. This season has been severe for people 65 years and older, with very high hospitalization rates being recorded.
Influenza antiviral drugs can treat flu illness. CDC recommends these drugs be used to treat people who are very sick or who are at high risk of serious flu-related complications who have flu symptoms. Early antiviral treatment works best.
