INDIANAPOLIS (AP) -- Indiana health officials have confirmed a case of measles in southern Indiana's Monroe County, and the affected individual visited Indianapolis International Airport while infectious.

The Indiana State Department of Health said Thursday that people who visited the airport on Aug. 22 and develop symptoms of measles should stay home and call their health care provider. Secondary cases would begin experiencing symptoms such as rash, fever, cough, runny nose, and red eyes by Sept. 12.

Measles is a highly contagious respiratory disease caused by a virus. It's rare in the U.S. because of the widespread availability of the measles, mumps, and rubella vaccine. However, visitors from other countries or U.S. citizens traveling abroad can become infected before or during travel.

Health officials say the Monroe County patient became infected overseas.
