Mumps is a contagious viral disease that spreads through saliva or mucus from the mouth, nose, or throat when infected people cough or sneeze.

Sharing food or utensils and contact with surfaces that have been contaminated with the virus also spreads the disease.

Symptoms usually appear 14-18 days after exposure, but can occur up to 25 days. Symptoms include fever, headache, muscle aches, tiredness, and loss of appetite followed by swelling of the salivary glands, which causes puffy cheeks and a tender, swollen jaw. Approximately one-third of infected people do not exhibit symptoms.

Persons with mumps should stay home until at least 5 days after symptoms appear.

Most people with mumps recover completely in a few weeks.

There is no treatment for mumps.

The most effective way to prevent mumps is by vaccination. Children and adults should be current with their immunizations.

Children should receive the first dose of mumps-containing vaccine, MMR, at 12 to 15 months, and the second dose at 4 to 6 years.

All adults without evidence of immunity born during or after 1957 should have one (1) dose of MMR.

Adults at higher risk, such as university students, healthcare personnel, international travelers, and persons with potential mumps outbreak exposure should have documentation of two (2) doses of mumps vaccine or other proof of immunity to mumps.

Persons born before 1957 are thought to be immune, since they were likely infected naturally.

According to the Centers for Disease Control and Prevention (CDC), in recent years, outbreaks have occurred in schools, colleges, and camps. Between January 1 to October 6, 2018, 1,885 cases of mumps were reported to the CDC. For more information, log onto or or call the Health Department at 815-334-4500.
