 Weekly Influenza Surveillance
Flu activity is still elevated and likely to continue for weeks in the United States. If you have not gotten your flu vaccine yet this season, you should get one now. This season’s vaccine protects against H1N1, the most common virus 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.
See CDC clinician advisory for this season.
Vaccination lowered risk of having to go to the doctor by about 60 percent for people of all ages
February 20, 2014 — This influenza season was particularly hard on younger- and middle-age adults, the Centers for Disease Control and Prevention reported in today’s Morbidity and Mortality Weekly Report. People age 18-64 represented 61 percent of all hospitalizations from influenza—up from the previous three seasons when this age group represented only about 35 percent of all such hospitalizations. Influenza deaths followed the same pattern; more deaths than usual occurred in this younger age group.
