• Mumps is becoming increasingly more common on college campuses in the United States.

Mumps is an illness characterized by the acute onset of unilateral or bilateral tender, self-limited swelling of the parotid or other salivary glands and lasting two or more days, not explained by another more likely diagnosis. Rare complications of mumps include orchitis, mastitis, oophoritis, deafness, and encephalitis. The infectious period for mumps is from two days before onset of symptoms through five days after symptoms appear. The incubation period for mumps from exposure to onset of illness ranges from 12-25 days. Mumps is spread via large respiratory droplets. A contact is defined as an individual who had face-to-face contact, within three feet of a presumed mumps case, or an individual who had direct contact with the case’s respiratory secretions. Individuals who are not fully vaccinated against mumps are at the highest risk of infection. Vaccine post-licensure studies have shown that one dose of mumps containing vaccine is 78% effective and two doses are 88% effective. Individuals who receive two doses of MMR vaccine are about nine times less likely to get mumps than unvaccinated people who have the same exposure to mumps virus. Some people who receive two doses of MMR can still get mumps, especially if they have prolonged, close contact with someone who has the disease. Outbreaks have been seen in groups such as schools, colleges and camps. When infected, persons who are vaccinated against mumps have less severe illness than unvaccinated persons.
