Mumps is a highly contagious viral infection with an incubation period of 14-18 days from exposure to onset of symptoms. The duration of the disease is approximately 10 days.
The initial symptoms of mumps infection are nonspecific (low-grade fever, malaise, headache, muscle aches, and loss of appetite). The classic finding of parotid gland tenderness and swelling generally develops the third day of illness. The diagnosis is generally made without the need for laboratory tests.
Serious complications of mumps include meningitis, encephalitis, deafness, and orchitis.
The MMR vaccine provides 80% effective immunity against mumps following a two-dosage schedule (12-15 months with booster at 4-6 years of age).
