BLOOMINGTON, Ind. (AP) — Health officials are investigating two confirmed cases of mumps at Indiana University in Bloomington.

The university and the Indiana State Department of Health confirmed the cases that are being investigated by state and Monroe County health officials.

An IU spokesman said two students who were roommates in an off-campus apartment contracted the disease. The school has issued an advisory saying health officials are working to identify anyone who may have been in close contact with the students.

Mumps is contagious and spreads through coughing and sneezing. Common symptoms are fever, headache, and painfully swollen salivary glands that can cause puffy cheeks. Most people recover within weeks. Outbreaks are rare.

The mumps vaccine is part of routine childhood shots.
