(NBC NEWS) — The flu does not discriminate against age, but this year the virus is mainly striking a younger crowd.
"Younger people, non-elderly adults are more likely this year to be hospitalized, to die from flu than they are in normal flu years," confirms Dr. Joe Bresee of the Centers For Disease Control.
A new report from the CDC finds people between the ages of 18 and 64 account for 61-percent of flu-related hospitalizations.
One reason may be the dominant viral strain.
H1N1 or "swine flu" is back, accounting for at least 95-percent of flu cases.
Experts say young and middle-aged adults appear to have low levels of natural immunity to help fight off H1N1, and vaccination rates in this age group are low.
