MADISON, Wis. (AP) -- State health officials are encouraging people to get their flu shots after Wisconsin's first influenza case of the season was confirmed.

Officials say an adult from northeastern Wisconsin is the first confirmed case of influenza for the 2011-12 season.

State Health Officer Dr. Henry Anderson says the most effective way to avoid getting the flu is to get a flu shot.

Anderson says there's still time for the vaccine to be effective.

Officials say this first case indicates Wisconsin's flu season is off to an early start. Normally the season for Wisconsin runs from November to March, peaking in late January or February.
