Transmission of Mumps
Mumps occurs in the United States, and the MMR (measles-mumps-rubella) vaccine is the best way to prevent the disease.
- Check your child’s immunization record or contact the doctor to see whether your child has already received the MMR vaccine.
- Get your child vaccinated on time; visit the immunization scheduler for newborn to 6-year-old children.
- Remember that some preteens, teens, and adults also need MMR vaccine; review the preteens and teen schedule and the adult schedule.
- Get an additional vaccine dose if your health department recommends it to a group you are part of during an outbreak.
- Recognize the signs and symptoms of mumps.
- Let your doctor know right away if you think you or someone in your family may have mumps.
Mumps is a contagious disease caused by a virus. It spreads through direct contact with saliva or respiratory droplets from the mouth, nose, or throat. An infected person can spread the virus by
- coughing, sneezing, or talking
- sharing items that may have saliva on them, such as water bottles or cups
- participating in close-contact activities with others, such as playing sports, dancing, or kissing
An infected person can spread mumps from a few days before their salivary glands begin to swell to up to five days after the swelling begins. A person with mumps should limit their contact with others during this time. For example, stay home from school and do not attend social events.
