Mumps

What is...

What is mumps?

Mumps is an infection that causes swelling of the parotid glands, which are inside the mouth near the upper teeth and make saliva.

The infection can cause other symptoms, including fever and headache.

A virus causes mumps. This infection is contagious, spread through droplet transmission when an infected person coughs or sneezes, and sometimes through direct contact with infected items.

The mumps virus most commonly affects children between 5 and 14 years of age, but infection can occur at any age. The time from infection to symptoms (incubation period) is usually 16 to 18 days, but ranges from 12 to 25 days.

Symptoms

Symptoms and signs

When infected with the mumps virus, one or both of the parotid glands often gets bigger, causing a marked swelling of the face, below and in front of the ears.

The child may have pain in the jaw and upper part of the throat when chewing, swallowing and speaking.

The child also may have a fever, poor appetite, difficulty swallowing, headache, muscle aches, nausea and vomiting.

However, some children with mumps infections have no symptoms at all, while other children have only mild cold-like symptoms.

The swelling of the parotid glands usually goes down after one week and disappears by 10 days, but the two sides may swell up and then go down in size at different times.

Complications

Complications

Most children recover completely from mumps but there can be serious complications.

Adolescent and adult males who become infected with mumps may develop orchitis, an infection in one or both of the testicles. This results in the testicles being swollen and painful for about a week and there may also be nausea, vomiting and fever. Mumps orchitis can cause some shrinkage of the testicles but only rarely causes sterility.

In rare cases, mumps can be complicated by meningitis, an inflammation of the lining of the brain and spinal column that causes symptoms such as headache, sensitivity to light, neck stiffness, and fatigue.

Inflammation of the parotid gland also rarely causes deafness, arthritis, heart, kidney, and other problems.

Home treatment

Treatment / What you should do

If you suspect your child may have mumps, you should consult a physician.

Because a virus causes the disease, antibiotics are not effective. A physician should be consulted if you suspect complications, especially meningitis or orchitis.

You can provide the child with relief of symptoms by giving the child plenty of fluids, medicine to bring any fever down or to relieve pain, such as acetaminophen or ibuprofen, and a warm compress on the cheek where the parotid glands are swollen.

The child should remain in bed and avoid infecting others, especially adult males who have not had the disease or have not been vaccinated.

Encourage your child to drink and offer food that is soft, so that painful chewing is avoided.

Prevention

Prevention

Mumps can result in serious complications.

The best way to protect your child from mumps is to have him vaccinated with the recommended measles, mumps and rubella (MMR) vaccine, which is given as a two dose series, with the first dose at 12-15 months, and a booster dose at 4-6 years.

Fortunately, mumps has become a rare disease among American children because everyone gets the MMR vaccine.

The mumps vaccine is made from a weakened form of the virus and must not be given to children who have severe problems with their immune system.

It should be used cautiously in children who are allergic to eggs, as the vaccine contains egg components.

Approximately 10% of children will experience some fever about 5 to 14 days after the MMR vaccination; some will develop a slight rash.

This is not dangerous and the child is not contagious.
