CHICAGO -- Illinois is reporting its first measles case this year in Cook County.
The patient became ill in mid-January, and test results came back positive for measles.
Before being diagnosed, the person may have exposed others while at three separate locations:
- Anyone at Northwest Community Hospital emergency room in Arlington Heights on Jan. 14
- Customers at the Supermercado Guzman in Palatine on Jan. 12 and 13
- Anyone at the Vista Clinic in Palatine on Jan. 16.
Measles is highly contagious and can be spread to an unvaccinated person simply by being in the same room as the patient.
Symptoms include fever, cough, runny nose and red eyes, with or without a rash.
Health officials say anyone who hasn't been vaccinated and is showing symptoms should see their doctor.
