Mumps Disease and Vaccine
Mumps: The Disease
Mumps virus is a contagious paramyxovirus that is comprised of a single-stranded RNA genome. Respiratory secretions transmit the virus and the infection begins in the nasopharynx and regional lymph nodes. After exposure, it generally takes 12 to 25 days for symptoms to develop. These symptoms typically include headache, muscle aches, tiredness, and loss of appetite. During this time, the virus is present in the blood and spreads throughout the body’s tissues. Parotitis, swelling of the parotid gland on one or both sides of the face under the ears and chin, is the most common clinical feature of a mumps infection, and typically occurs within the first two days. Up to 30 percent of people infected with mumps will have no symptoms of infection and up to 50 percent may exhibit signs of a mild nonspecific illness.
Mumps is generally a mild disease in childhood, but it can result in complications, though mostly in adults. Complications of mumps include inflammation of the testicles in males, inflammation of the breast tissue and ovaries in females, meningitis, encephalitis, and loss of hearing. Fertility problems following mumps infection are rare. Mumps rarely results in death and most people recover from mump infection within a few weeks. Learn more about Mumps…
There are two mumps containing vaccines available for use in the United States - MMRII - a combination mumps-mumps-rubella(MMR) live virus vaccine and ProQuad - a combination mumps-mumps-rubella-varicella (MMR-V) live virus vaccine. Currently, the CDC recommends that children receive two doses of a mumps containing vaccine, with the first dose between the ages 12-15 months, and the second dose between the ages 4-6 years. The CDC also recommends that individuals born after 1957 and have no laboratory evidence of immunity or documentation of vaccination should receive at least one dose of MMR vaccine. Two doses of MMR vaccine are also recommended for healthcare personnel, students entering college and other post-high school educational institutions, as well as international travelers.
The CDC also recommends MMR vaccination for infants between 6 and 12 months of age who may be traveling internationally. However, both ProQuad and MMRII have been approved only for use in for children older than 12 months of age. Learn more about Mumps vaccine…
