The incubation period for mumps can be 12-25 days, but the average is 16-18 days. Children usually recover from mumps in about 10-12 days. It takes about 1 week for the swelling to disappear in each parotid gland, but both glands don’t usually swell at the same time. Mumps can be prevented by vaccination. The vaccine is given as part of the measles-mumps-rubella (MMR) immunization, which is usually given to children at 12-15 months of age. A second dose of MMR is generally given at 4-6 years of age. Mumps most commonly occurs in children ages 2 - 12 who have not been vaccinated against the disease. However, the infection can occur at any age. The time between being exposed to the virus and getting sick (incubation period) is usually 12 - 24 days. Mumps may also infect the: 1  Central nervous system. 2  Pancreas. 3  Testes.  After 16 to 18 days, on average, symptoms can appear. This period between mumps transmission and the start of mumps symptoms is called the incubation period.. In some cases, the incubation period can be as short as 12 days or as long as 25 days. A person is not contagious during the early mumps incubation period. A person is most contagious about three days prior to the onset of the swelling of the salivary glands (called parotitis) to nine days after the onset of symptoms.  Symptoms of mumps.

Two doses of mumps vaccine are 88% (range 66% to 95%) effective at preventing the disease; one dose is 78% range (49% to 91%) effective.

When a child becomes infected with the mumps virus, the virus begins to multiply within the nose, throat, and lymph glands in the neck. The virus can also enter the blood and spread to other parts of the body. After 16 to 18 days, on average, mumps symptoms can appear.
