Flu activity.

Flu activity is still low. Flu season typically starts in October or November.

Now is the perfect time to go and get the flu shot. It takes about 2 weeks for protection.

This season's flu shot looks to be a good match for the circulating viruses.

Two kids in Minnesota got H3N2v, a "swine" flu, after contact with pigs at an agricultural fair.

The CDC calls these influenza viruses variants as they generally circulate in pigs not humans.

Like with the avian flu, human to human transmission is rare.
