Officials say at this time they don’t know the source of the infection. Measles is a highly contagious respiratory disease with a characteristic rash.

Public health officials say students, staff and faculty at the facility have been notified and anyone who hasn’t been vaccinated for measles has been instructed to stay away from unvaccinated individuals for the next three weeks.
