What is mumps?
Mumps is an infectious viral disease that causes fevers and swollen salivary glands, mostly in children. A mumps vaccine is available and given as part of the measles, mumps, rubella (MMR) or measles, mumps, rubella, varicella (MMRV) combined childhood vaccinations.
Mumps is caused by the mumps virus.
When an infected person sneezes or coughs, the virus spreads via millions of tiny droplets, each containing many viruses that are spread into the air. If a droplet enters your nose or mouth, you may then be infected with the virus. The droplets can also collect on surfaces and objects; you can catch the virus by touching an infected surface and then touching your nose or mouth area.
The mumps can be transmitted from exposure to infected bodily fluids such as saliva.
Mumps is a classic childhood disease and is found worldwide. The most common age for catching mumps is 5-9 years, and about 90% of people reach their teen years already immune to mumps, as a result of previous exposure or vaccination.1
People who catch mumps as adults tend to have more serious symptoms and also stand a higher chance of complications.
Signs and symptoms
The symptoms of mumps usually appear about 2-3 weeks after the infection. About a third of all people infected with mumps have no symptoms at all 1.
The most distinctive sign of mumps is a painful inflammation of the salivary glands. The salivary glands that are most commonly affected are the two parotid glands, located in the sides of the face. The area can become painful, tender and swollen. This sign, also known as parotitis, appears in 60-70% of all mumps infections1. One or both glands may be affected.
Mumps causes parotitis, an inflammation of the salivary glands.
Other symptoms of mumps can often include:
- Mild fever;
- Muscle ache;
- Feeling tired, weak and ill, and;
- Lack of appetite.
Symptoms of mumps normally last 3-4 days and parotitis can remain for about 7-10 days, then go away naturally unless there are complications. An infected person is able to infect others for a day or two before parotitis appears and for a period of about a week afterwards.
Methods for diagnosis
Your doctor will diagnose mumps by noting the symptoms, especially the enlarged salivary glands. That is usually enough, but blood tests (checking for the presence of the virus and for antibodies against it) can confirm the diagnosis if necessary.
Types of treatment
There is no specific treatment for mumps. Treating a mumps patient focuses on relieving the symptoms while the patient’s immune system handles the disease.
Some measures that can be taken to ease the effect of mumps symptoms are:
- Medicines to reduce fever, and;
- Drinking plenty of fluids to prevent dehydration.
Relieving pain of the parotid glands
If the parotid glands swell and become painful, some things you can do to ease the pain and discomfort include:
- Eating soft foods;
- Gargling with warm salt water, and;
- Applying icepacks or heat packs.
Mumps is usually not a serious condition. In rare cases, complications can be annoying and in even rarer cases, serious or even life-threatening. Some of the more common complications of mumps include:
An inflammation of a testicle, or orchitis, appears in about 15-30% of teenage and adult males who are infected with mumps. The testicle may enlarge, be painful and tender to the touch. In about 20% of orchitis cases, both testicles are affected1.
The discomfort can be relieved somewhat by warm compresses and by wearing supportive underwear. The condition usually goes away naturally after about four days, but can occasionally last for up to six weeks.
Orchitis can sometimes reduce fertility and in rare cases, cause infertility.
Swollen ovaries, swollen breasts
An inflammation of the ovaries, or oophiritis, can appear in about 5% of teenage and adult women infected with mumps1. The infected woman can feel ill, have a fever and pain in her pelvis and lower abdomen.
Inflammation of the breast, or mastitis, can also occur in teenage or adult females.
Miscarriage in first trimester
Women who are infected with mumps during the first trimester of pregnancy are in danger of miscarriage. However, a mumps infection during pregnancy has not been found to cause any birth defects in pregnancies that carry to full term.
Viral meningitis and encephalitis
An inflammation of the membranes around the brain (meningitis) or of the brain itself (encephalitis) can occur as a result of a mumps infection, especially in male teenagers and adults. It can cause nausea, vomiting and sensitivity to light. It usually passes within two weeks. Serious, life-threatening meningitis and encephalitis can occur as a result of mumps, but is uncommon.
A small number of people who contract mumps will experience hearing loss, or even become temporarily deaf in one or both ears. This will usually pass, along with the other symptoms of mumps, but permanent hearing loss can occur in some cases.
Severe inflammation of the pancreas, or pancreatitis, is a rare complication of mumps1.
Mumps is usually not a serious health risk and goes away naturally after a few days. Long-term harm is rare.
A mumps vaccine is available and given routinely to children, usually from 12 months of age, as part of the measles, mumps, rubella (MMR) or measles, mumps, rubella, varicella (MMRV) combined vaccine.
In case of an outbreak of mumps in a community, unvaccinated children may be asked to stay home and not come to day care or school until the situation improves.
A vaccine to prevent the mumps infection is available.

Measles is a highly contagious viral disease which mainly affects children. Children who get measles typically have a fever, sore throat, spots in the mouth and a generalised skin rash. There can be serious complications from measles. Fortunately, it is now rare in developed nations due to the measles vaccine.
Rubella is a viral disease which generally causes a mild illness and usually resolves after a few days. However, death or serious birth defects can occur if the virus is contracted during pregnancy. Vaccines exist for children at twelve and eighteen months and also for adults.

Chickenpox is a common, contagious childhood illness, caused by the varicella virus. It causes a distinctive, itchy rash, and normally resolves on its own. A vaccine is available that can help reduce your chance of getting the condition.
