- Two measles cases have been confirmed in Cook County: one in a Chicago resident who traveled internationally through O'Hare Airport and another in a suburban resident with unknown vaccination status.
- The Chicago case involves an individual who developed a rash on April 25 and has been isolating at home since diagnosis, while the suburban case was hospitalized on April 28 and quickly isolated.
- Authorities have identified multiple potential public exposure sites, including O'Hare Airport, a Chicago public library branch, and local businesses in Lyons, Stickney, and Berwyn.

- Officials emphasize the importance of the MMR vaccine, which is 97% effective after two doses, and are offering free vaccinations at local clinics to prevent further spread.
