Penn State's University Health Services, an on-campus outpatient healthcare facility in University Park, Pa., confirmed 12 cases of mumps on campus in the past several weeks.
In accordance with CDC and Pennsylvania health department protocols, the 12 infected students have been isolated.
UHS is urging those who have not been vaccinated for mumps to take extra precautions, especially as graduation and other end-of-the semester activities bring large amounts of people to campus.
UHS staff members notified those who have had direct contact with any of the individuals with confirmed mumps cases.
Mumps is a highly infectious disease passed through salvia and respiratory secretions.
