It's not too late to protect yourself with a flu shot, the McHenry County Department of Health advises.
With a surge of influenza cases nationwide, the health department is encouraging people six months of age or older to get the shot.
The latest report from the U.S. Centers for Disease Control and Prevention for the last week of December showed widespread flu activity in 25 states and Illinois, which have resulted in six pediatric deaths. Influenza-type illnesses have been reported in 19 other states.
Flu season typically runs through May, with cases hitting their peak in January and February. Once vaccinated, it takes the average person about two weeks to develop antibodies.
The vaccine is available at doctor's offices, clinics, pharmacies, grocery stores and other locations countywide.
