Public Health England is investigating reports of a number of cases of suspected mumps at the Toot Hill School in Bingham in Nottinghamshire.
They're advising teenagers and young adults (aged 15-24 years) to protect themselves against mumps by having the MMR jab.
To be fully protected, children and adults need to have two doses of the MMR vaccine.
What is mumps ?
Public Health England teams describe mumps as a contagious viral infection caused by a paramyxovirus. Swelling of the parotid glands is the most common symptom of mumps. The parotid glands are a pair of glands responsible for producing saliva. They're located in either side of the face, just below the ears.
More general symptoms often develop a few days before the parotid glands swell. They include:
- joint pain
- feeling sick
- dry mouth
- mild abdominal pain
- feeling tired
- loss of appetite
- a high temperature (fever) of 38C (100.4F), or above
If you have mumps, you can help prevent it spreading by:
- regularly washing your hands with soap and water
- using and disposing of tissues when you sneeze
- avoiding school or work for at least 5 days after the onset of swelling
