ATLANTA, Feb. 20 (UPI) -- This year's influenza season was hard -- more deaths and more hospitalizations -- on younger- and middle-age adults ages 18 to 64, U.S. officials say.
The Centers for Disease Control and Prevention's Morbidity and Mortality Weekly Report found U.S. adults ages 18 to 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.
