What is mumps?

Mumps is a disease caused by the mumps virus. Mumps was a common childhood disease before immunization. Now it is more common in young adults.

Mumps can cause encephalitis, an inflammation of the brain, which can lead to seizures or brain damage. About 1 in 20 people with mumps get mumps meningitis, an infection of the lining of the brain.

Mumps can also cause temporary deafness. Permanent deafness occurs in less than 1 in 20,000 people who get mumps.

About 1 in 4 adult men and teenage boys with mumps have painful swelling of the testicles and 1 in 20 women and teenage girls have swelling of the ovaries. Both of these conditions are temporary and rarely result in permanent damage or sterility.

Mumps infection in the early stage of pregnancy may increase the rate of miscarriage but has not been shown to cause birth defects.

Is there a mumps vaccine?

There are 2 vaccines available in B.C. that provide protection against mumps:

  1. Measles, Mumps, Rubella (MMR) Vaccine
  2. Measles, Mumps, Rubella and Varicella (MMRV) Vaccine

The vaccines are provided free as part of routine childhood immunizations and to others that need protection against mumps. For more information, see HealthLink BC File #14a Measles, Mumps, Rubella (MMR) Vaccine and HealthLinkBC File #14e Measles, Mumps, Rubella and Varicella (MMRV) Vaccine.

How is mumps spread?

Mumps is contagious and spreads easily. Mumps is spread by contact with saliva or mucus from the mouth, nose, or throat of an infected person. When an infected person coughs or sneezes, the virus spreads through droplets in the air. You can be exposed to the virus even if you are 2 meters away from someone with mumps. You can become infected when you breathe in these droplets or touch objects contaminated with the virus. Sharing food, drinks or cigarettes, or kissing someone who has the virus can also put you at risk.

What are the symptoms?

Symptoms may include fever, aches and pains, headaches, and swelling of the salivary glands, especially the parotid glands that are at the side of the cheeks.

Up to 1 in 5 people with mumps do not have any symptoms. About 1 in 3 people with mumps do not have salivary gland swelling. However, they can still spread the mumps virus to other people.

Symptoms can appear from 12 to 25 days after a person is infected with the mumps virus.

What if I have been exposed to mumps?

If you have been exposed to someone with mumps and have not had the disease or the recommended number of doses of a mumps vaccine you should get immunized. Although the mumps vaccine may not prevent you from becoming ill if you have been exposed to mumps recently, it will protect you against future exposures to the mumps virus. Check your immunization record to see how many doses of mumps vaccine you have received. To be protected from mumps it is recommended that those born in 1970 or later receive 2 doses of a mumps vaccine. People born before 1970 are likely immune to mumps and do not need to be immunized. If you need to be immunized contact your health care provider to schedule an appointment.

What should I do if I think I have mumps?

If you have swollen salivary glands, especially if you have been in contact with a person with mumps or traveled to an area with a mumps outbreak, have yourself examined by a health care provider. It is best to call ahead so that you can be seen quickly and without infecting other people. Mumps can spread easily in places like waiting rooms and emergency rooms. The doctor or triage nurse can make sure that you are taken into a closed area for an examination and attend the clinic at a time when the waiting room is empty. Bring your immunization record with you. A physical examination, blood test, and swab of your salivary glands inside your mouth or a urine sample will be collected to make the diagnosis of mumps.

How can I prevent spreading mumps to others?

A person with mumps can spread the virus to others from 7 days before to 9 days after symptoms develop. If you have mumps you can help prevent spreading it to others by:

  • Staying at home for at least 5 days after your salivary gland swelling started.
  • Washing your hands regularly.
  • Coughing or sneezing into a tissue or sleeve rather than your hands.
  • Not sharing food, drinks or cigarettes, or kissing others.

What is the home treatment?

After seeing a health care provider, the following home treatment tips may help you to be more comfortable while you rest and recover.

Acetaminophen (e.g. Tylenol®) or ibuprofen* (e.g. Advil®) can be given for fever or soreness. ASA (e.g. Aspirin®) should not be given to anyone under 18 years of age due to the risk of Reye Syndrome.
*Ibuprofen should not be given to children under 6 months of age without first speaking to your health care provider.

For more information on Reye Syndrome, see HealthLinkBC File #84 Reye Syndrome.

  • Drink plenty of fluids such as water, juice and soup, especially if you have a fever.
  • Get plenty of rest.
  • Use an ice pack or heating pad for a swollen or painful jaw. Be sure to place a light towel on the jaw to protect the skin.
  • Avoid sour foods and liquids because the inflamed salivary glands are very sensitive to sour tastes.
  • Eat ice chips or flavoured ice treats, and soft foods that do not require chewing.
