 Weekly Influenza Surveillance
Flu activity is low in most of the United States, but a wave of influenza B virus activity is affecting parts of the country. It's possible that significant flu activity could continue into May. CDC still recommends that people get a flu vaccine if they have not yet this season. And remember that flu antiviral drugs are a second line of defense to treat flu illness. People at high risk of serious flu illness should call a health care provider if they get flu symptoms.

Antigenic characterization can give an indication of the flu vaccine’s ability to produce an immune response against the influenza viruses circulating in people.
