Cook County public health officials strongly urge residents to get vaccinated against measles if they aren't already.

County health officials are making this urgent plea after at least five measles cases were reported in the City of Chicago over the last couple of weeks.

In the Village of Park Forest, Assistant Director of Recreation, Parks, & Community Health Margaret Lewis said it's important for residents to understand what the disease is and know what steps can be taken to prevent the spread of measles.

"Measles is a virus that spreads easily through the air when an infected person coughs, sneezes, or speaks," Lewis said. "Measles is a highly infectious disease caused by a virus. People of any age can get measles, but the disease is most common — and most deadly — in children."

Lewis added, "Much like Covid-19, it can also spread when infected droplets land on a surface and someone touches it. So good hand hygiene and being up-to-date with the Measles, Mumps, and Rubella vaccine are essential to reduce the spread."

Lewis said measles can cause serious complications such as pneumonia and encephalitis (brain swelling). 

Most people are vaccinated routinely in childhood and are not at high risk. Of most concern are people who have not been vaccinated. Individuals who think they have been exposed should check with their healthcare provider about protection through prior vaccination or the need for vaccination.
