Q: Is mumps a serious disease?Ī: Make sure you and your family are up to date on your MMR vaccine. See Mumps Cases and Outbreaks for more information. In some years, there are more cases of mumps than usual because of large outbreaks.

From year to year, the number of mumps cases can range from roughly a couple hundred to a couple thousand. In some cases, the disease caused complications, such as permanent deafness in children and, occasionally, swelling of the brain (encephalitis), which in rare cases resulted in death. If a vaccinated person does get mumps, they will likely have less severe illness than an unvaccinated person.īefore there was a vaccine, mumps was a common childhood disease in the United States. However, some people who receive two doses of MMR can still get mumps, especially if they have prolonged, close contact with someone who has the disease. People who have received two doses of the MMR vaccine are about nine times less likely to get mumps than unvaccinated people who have the same exposure to mumps virus.
