This flu season was particularly hard on young adults.
The Centers for Disease Control and Prevention (CDC) reported that individuals between the ages of 18 and 64 made up 61 percent of all flu-related hospitalizations this year, a PR Newswire news release reported. Last season this age group made up only about 35 percent of influenza hospitalizations.
"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," CDC Director Tom Frieden, M.D., M.P.H, said in the news release. "The good news is that this season's vaccine is doing its job, protecting people across all age groups."
