COLUMBUS, Ohio (WTVN) -- Public health officials are investigating a possible outbreak of mumps at Ohio State University, where nine students are reported to have the contagious infection.

"The onset of their illness started as early as February 12th for some of them and has continued on for others until March 3rd," said Mysheika Roberts, medical director for Columbus Public Health. "We have five female cases and four male cases."

The department is working to find out whether there is a connection between the cases. Roberts said officials are in the early stages of their investigation and are interviewing students.

Ohio State is preparing for spring break next week, and some students may already be leaving campus.

"We are concerned that this could spread further either on campus, or in the general community, or communities where these students may be traveling for spring break."

Roberts says the infected students have been told to stay isolated from others.

Mumps is a viral infection that typically starts with fever, fatigue and body aches. Roberts says the treatment is rest and fluid.
