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 six have died.
U.S. health officials say the strain of influenza virus going around this year has been linked to more hospital admissions and deaths. They say it isn't too late to get a flu shot, and there's no shortage of flu vaccine.
