Flu is on the upswing in Illinois along with the most of the rest of the nation.
Illinois Department of Public Health spokeswoman Melaney Arnold says almost 150 people have been admitted to intensive care units with the flu this season and five have died.
Eight Chicago-area hospitals were turning away ambulances Monday night as they dealt with a flood of patients with flu-like symptoms.
U.S. health officials say the strain of influenza virus going around this year has been linked to more hospital admissions and deaths.
It isn't too late to get a flu shot, and there's no shortage of flu vaccine.
Dr. Julie Morita of the Chicago Department of Public Health says city residents can call 311 to find out where to get a free flu shot.
