Cases of influenza are spiking nationwide and across the state as public health officials urge that it's not too late to get a flu shot.
Hospitals across Illinois counties are seeing more people coming in with flu-like symptoms and testing positive for the illness.
Common symptoms include a fever of 100 degrees or higher, along with a cough and sore throat.
Melaney Arnold, with the Department of Public Health, says the typical flu season peaks between December and March but can last through May.
"We are experiencing what’s called widespread influenza activity right now," she said. "Compared to last year, we were seeing sporadic flu activity. Last year the peak, however, was a little bit later than we typically see.”
Arnold recommends being wary of visiting people in hospitals with the illness. She also urges strong hand-washing practices, and staying home when you're sick.
