Indiana University officials say they are working to control a quickly-growing outbreak of the mumps on the Bloomington campus.

The number of mumps cases at Indiana Universitys Bloomington campus has more than doubled in the past week.

Indiana University officials say seven students have now been diagnosed with mumps amid an outbreak of the virus on the Bloomington campus.

Indiana has seen a drastic increase in mumps cases in recent years, and the CDC reports mumps cases are at a 10-year high nationwide.

Purdue is asking anyone with symptoms to stay home. Symptoms can include fever, headache, muscle aches and swollen glands.

There are 45 confirmed cases of mumps on college campuses and five probable cases.

The Monroe County Health Department says the cases do not appear to be linked, which indicates that the virus is spreading in the community and mumps cases could increase.

Public health experts are noting the differences in vaccination requirements at Indiana colleges in the wake of three schools announcing cases of the mumps this year.

Butler and IU are offering free mumps vaccinations. People who have already been vaccinated can still get the virus as antibodies wane over time.

Indiana University is investigating two confirmed cases of mumps on the Bloomington campus that so far appear unconnected. The university said Wednesday the cases were identified two weeks apart.
