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.

As flu season is wrapping up in the United States, other parts of the world are bracing for the start of their seasons. Thanks to CDC guidance and donations from Partnership for Influenza Vaccine Introduction (PIVI), this year Laos is vaccinating against seasonal influenza for the third year running, and Nicaragua is vaccinating pregnant women against flu for the second year in a row.
