Health officials in Illinois are warning people of a possible measles exposure at Chicago Midway Airport and the Delnor Hospital.
An Illinois resident with a confirmed case of measles visited both the airport and hospital last week. The passenger was unvaccinated and infectious. Health officials are now working to notify those passengers on the flight he arrived on.
While measles is a highly contagious disease, most people are vaccinated routinely in childhood and are not high risk, health officials said. People who have not been vaccinated are of most concern.
