Mumps is a highly contagious viral disease that can be transmitted through the nose, mouth and throat. Symptoms include swelling of the face and jaw, fever and body pains. The incubation period is 12 to 25 days and the symptoms usually appear 16 to 18 days after exposure.
This is the first major mumps outbreak on the main campus for at least 14 years.
A person with mumps is considered contagious two days before his face swells up, until five days later, according to a university statement. It is recommended that people with mumps isolate themselves to be less likely to infect others.
