ATLANTA (AP/WMOT) — Health officials say the flu season is finally here, but so far few cases have been reported in Tennessee.

Until this month, there weren't enough cases in the U.S. to signal the start of the season. 

The Centers for Disease Control in Atlanta says this is the slowest start to the flu season in nearly 25 years. Flu season usually starts in December or January. Often, it's half over by this point in the year.

Here in Tennessee, the CDC is calling the incidence of flu "sporadic."
