At least 13 Ohio State University students have the Mumps.
On Friday, health officials say 7 females and 6 males have confirmed cases. The students range in age from 18 to 22 years.
The infected students currently live in both dorm rooms and off-campus apartments - some of which are related to fraternities or sororities.
The majority of the infected students say they have received a vaccination for the Mumps.
The University sent out a warning to students Thursday night in an attempt to stop the spread of the disease.
School officials say they expect the number of cases to rise.
Meanwhile, health officials say they have received calls from doctors in other parts in Ohio who have said they are also treating patients who are Ohio State University students with suspected cases of the Mumps.
Mumps is a viral infection that typically starts with fever, fatigue and body aches. The treatment is rest and fluid. Those infected become contagious two days before showing symptoms.
For all Ohio State students, the Wilce Student Health Center is available. Visit the website at for hours of operation and a list of additional facilities that provide medical care off campus and after hours.
