Officials say that all of the cases have some affiliation with the university and have gradually increased over the last month.

“We are working to identify stem causes,” said Dr. Steve Alles, of the Philadelphia Health Department. “It would be a typical social event on college campus.”

Mass vaccination clinics are set for Wednesday and Friday on campus. Students, faculty and staff will be able to receive the Mumps-Measles-Rubella (MMR) vaccine free of charge. The clinics will be held in Temple’s Mitten Hall’s Great Court on Wednesday and Friday from 9 a.m.– 4 p.m. No appointments are necessary, but you will need to have your OWLcard present.

Health officials say close to 1,000 people have received booster shots.

“We are prepared for 1,800 tomorrow,” said Denys.

Temple students have largely gone about their educations, unaffected by illness, but well aware of the stories circulating far beyond campus about the situation.

“I told my friends, too, you got to go out and get it done,” said student Goodwill Agbaadem.

Mumps is a highly infectious disease passed through saliva and respiratory secretions. While the incubation period is 12 to 25 days, symptoms often appear 16 to 18 days after exposure. The symptoms for the mumps are similar to the flu and often include tender swollen glands below the ear and along the jawline on one or both sides of the face and neck, headache, fever and cold-like symptoms. People with mumps are considered infectious from two days before swelling begins through five days after the start of swelling. You can learn more about mumps on the Centers for Disease Control and Prevention website.
