INDIANAPOLIS (AP) - State health officials are urging people in northeastern Indiana to make sure their immunizations are up to date following a measles outbreak in the region.

The Indiana State Department of Health said Friday that 13 case of measles have been confirmed, up from five cases last week. Twelve of the cases were in Noble County, with one in LaGrange County.

Local health departments in some area counties will be offering vaccine at no cost to those who believe they may have been exposed to the disease.

Measles is a rare disease in the United States because of the widespread availability of a measles vaccine. But officials say visitors from other countries or citizens traveling abroad can spread the disease, which often includes a high fever and rash.
