• Mumps is a serious disease caused by a virus.
  • It is spread person-to-person through the air.
  • Mumps typically causes painful swelling of the salivary glands near the cheeks, but it can also lead to deafness, brain or spinal cord infection, and painful swelling of the testicles.
  • Mumps virus is very contagious, so when one person gets infected, it’s easy for the disease to spread. Mumps outbreaks can start when infected people bring the disease into the United States from other countries.
  • Vaccination is the best way to prevent mumps. Vaccinated people who contract mumps because of very close contact with an infected person typically have a milder illness than unvaccinated people.
