The CDC says flu season is off to a slow start this year. As of now, only Georgia is seeing high levels of infections, but cases are being reported throughout the nation.
This year's predominant strain of flu so far is H1N1, and this year's flu vaccine seems fairly effective. The strain that caused last year's extremely severe flu season, N3N2, is far less prevalent this year.
Last year, the flu killed 80-thousand people and sent a million to the hospital. The CDC says plenty of this year's vaccine is still available.
