CHICAGO, Illinois: The Chicago and Cook County health departments say that two people in Cook County have measles.

These are the first measles cases in the area this year. One person is an adult who lives in the suburbs of Cook County, but it's not known if they were vaccinated.

The other case is an adult from Chicago who traveled internationally through O'Hare Airport in early April.

This person had one dose of the measles vaccine and developed a rash on April 25. They have been staying at home since being diagnosed.
