Measles is easily spread through the air when someone coughs or sneezes. People can also get sick when they come into contact with mucus or saliva from an infected person. Measles can cause serious complications such as pneumonia and encephalitis (swelling of the brain). Children younger than 5 years old and adults older than 20 years old are more likely to suffer from complications.

CCDPH strongly encourages all suburban Cook County residents to stay up to date with all recommended vaccinations, including for measles. Illinois residents can check their immunization records using the Illinois Department of Public Health’s online Vax Verify portal.

Unvaccinated individuals who do not have a healthcare provider are encouraged to contact Cook County Health at 833-308-1988 to schedule a vaccination appointment at a community health center in Chicago or suburban Cook County.
