WTVO/WQRF - More than 100 are in intensive care as flu season starts to pick up.
The Illinois Dept. of Public Health says there are 122 flu-related cases where patients are in intensive care units. At least six people so far have died.
The recent activity is prompting the IDPH to remind everyone to get a flu vaccine.
"Flu activity typically peaks in January, but can run into April" says IDPH Director Dr. LaMar Hasbrouck. "Getting vaccinated now can help protect you from the flu in the coming months."
Dr. Hasbrouck says he only expects the number of flu cases to go up.
Symptoms of the flu include: fever, cough, sore throat, runny or stuffy nose, body aches, head aches, chills, and fatigue. People most at risk of having a serious flu complication is anyone with an underlying chronic medical condition such as asthma, diabetes, or heart disease. Pregnant women and children younger than five years old are also vulnerable.
