A student who lives on campus has reported a probable case of mumps to University Health Services (UHS), a staff member confirmed.

This is the second probable case of mumps reported in the past two weeks. The first student who reported symptoms is an off-campus student, but Evan Pattishall, clinical director at UHS, said students shouldn't be worried.

"If this truly is mumps, usually we would expect to see more cases by now. I think that what we're hoping is that neither of these are the true mumps virus," Pattishall said.

The second case was reported on Monday during an examination at UHS. Blood was drawn to test for mumps, but results will not be available until at least next week.

Even after the results are available, "sometimes you have to do one test, then in two or three weeks, another test," Pattishall said.

Results from the first student's test are not available yet either; the student was tested on April 6. Those results should be available by the end of this week or early next week.

Mumps is a communicable disease caused by a virus that spreads through direct contact with respiratory secretions or saliva that can have fairly significant complications. Mumps can spread rapidly, especially on college campuses because of the confinement in dorms, classes and cafeterias, said Curtis Allen, Center for Disease Control (CDC) spokesman, after the first reported probable case of the mumps at Penn State.

Two Measles, Mumps, Rubella vaccinations are required for Penn State students, but the vaccine isn't 100 percent effective, Pattishall said.

The on-campus student had two doses of the vaccine, he said.

UHS will not release any information about the student's identity or about his or her case. But Pattishall said "the student's been isolated and any significant contacts that would have resulted in communication of the disease have been contacted, or are in the process of being contacted, so they know what to look for."
