CDC Reports Flu Hit Younger People Particularly Hard This Season

Vaccination lowered risk of having to go to the doctor by about 60 percent for people of all ages

This influenza season was particularly hard on younger- and middle-age adults, the Centers for Disease Control and Prevention (CDC) reported in today’s Morbidity and Mortality Weekly Report (MMWR). 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.

A second report in this week’s MMWR showed that influenza vaccination offered substantial protection against the flu this season, reducing a vaccinated person’s risk of having to go to the doctor for flu illness by about 60 percent across all ages.

“Flu hospitalizations and deaths in people younger- and middle-aged adults is a sad and difficult reminder that flu can be serious for anyone, not just the very young and old; and that everyone should be vaccinated,” said CDC Director Tom Frieden, M.D., M.P.H. “The good news is that this season’s vaccine is doing its job, protecting people across all age groups.”

U.S. flu surveillance data suggests that flu activity is likely to continue for a number of weeks, especially in places where activity started later in the season. Some states that saw earlier increases in flu activity are now seeing decreases. Other states are still seeing high levels of flu activity or continued increases in activity.

While flu is responsible for serious illness and death every season, the people who are most affected can vary by season and by the predominant influenza virus. The currently circulating H1N1 virus emerged in 2009 to trigger a pandemic, which was notable for high rates of hospitalization and death in younger- and middle-aged people. While H1N1 viruses have continued to circulate since the pandemic, this is the first season since the pandemic they have been predominant in the U.S. Once again, the virus is causing severe illness in younger- and middle-aged people.
