(CHICAGO) -- According to the Illinois Department of Public Health, the number of people getting sick with the flu in the state is on the rise, and officials expect the number of people stricken with the flu to increase even more by the end of the season.
The city of Chicago has also seen a rise in the number of people being treated at local hospitals.
The Centers for Disease Control and Prevention added Illinois and Indiana to its watch list this week and is now part of a group of 30 other states on the list of widespread flu activity.
The flu season ends in March and health experts say it's not too late for those who want to be innoculated.
Influenza symptoms include fever, cough, sore throat, runny nose, headaches, bodyaches and chills.
