Mumps is most recognisable by the painful swellings in the side of the face under the ears (the parotid glands), giving a person with mumps a distinctive "hamster face" appearance.
Other symptoms of mumps include headaches, joint pain and a high temperature, which may develop a few days before the swelling of the parotid glands.
When to see a GP
It's important to contact a GP if you suspect mumps so a diagnosis can be made.
Your GP can usually make a diagnosis after seeing and feeling the swelling, looking at the position of the tonsils in the mouth and checking the person's temperature to see if it's higher than normal.
Let your GP know in advance if you're coming to the surgery so they can take any necessary precautions to prevent the spread of infection.
If your GP suspects mumps, they should notify your local health protection team (HPT). The HPT will arrange for a sample of saliva to be tested to confirm or rule out the diagnosis.
How mumps is spread
Mumps is spread in the same way as colds and flu: through infected droplets of saliva that can be inhaled or picked up from surfaces and transferred into the mouth or nose.
A person is most contagious a few days before the symptoms develop and for a few days afterwards.
During this time, it's important to prevent the infection spreading to others, particularly teenagers and young adults who have not been vaccinated.
If you have mumps, you can help prevent it spreading by:
- regularly washing your hands with soap
- using and disposing of tissues when you sneeze
- avoiding school or work for at least 5 days after your symptoms first develop
You can protect your child against mumps by making sure they're given the combined MMR vaccine for mumps, measles and rubella.
The MMR vaccine is part of the routine NHS childhood immunisation schedule.
Your child should be given 1 dose when they're around 12 to 13 months and a second booster dose at 3 years and 4 months.
Once both doses are given, the vaccine provides 95% protection against mumps.
Treatment for mumps
There's currently no cure for mumps, but the infection should pass within 1 or 2 weeks.
Treatment is used to relieve symptoms and includes:
Mumps usually passes without causing serious damage to a person's health. Serious complications are rare.
But mumps can lead to viral meningitis if the virus moves into the outer layer of the brain.
Other complications include swelling of the testicles or ovaries (if the affected person has gone through puberty).
Most cases of mumps occur in young adults (usually born between 1980 and 1990) who did not receive the MMR vaccine as part of their childhood vaccination schedule or did not have mumps as a child.
Once you have been infected by the mumps virus, you normally develop a life-long immunity to further infection.
