MADISON, Wis. (AP) -- Wisconsin health officials are urging residents to get a flu shot after a rise in confirmed cases of influenza.

State Health Officer Dr. Henry Anderson says even though this flu season started late, it's not too late to get vaccinated.

Anderson says anyone over 6 months old can be vaccinated. He says supplies are available.

According to the U.S. Centers for Disease Control and Prevention, this is the latest start to the flu season in 29 years.

Flu symptoms include body aches, fatigue, fever and sore throat. Symptoms appear one to five days after infection.
