Kari Coe, the Infectious Disease Manager for St. Charles warns it's early in the season.

"We are definitely on an up upswing overall for the year.  As the CDC has been saying, it's a severe flu and its an earlier flu season.  What we're saying is it's a more severe flu season this year."

There are only three states in the U.S. not seeing widespread flu cases -- California, Mississippi,  and the District of Columbia.
