Possible exposure to mumps

You are receiving this information as you or your child attended a medical clinic recently.

A person infectious with mumps was in the same area of the clinic as you (and anyone accompanying you) at around the same time. There is a small possibility that you, or those with you, could have contracted mumps.

The risk of getting ill is particularly high for those who have had no mumps vaccinations or not had mumps before. It may take up to 25 days for an unprotected individual to develop the disease after exposure to an infectious person.

You do not need to do anything if:

  • You have had at least one dose of mumps vaccine (MMR) documented. Your vaccinations should be in your Plunket or Well Child book or your practice may have records.
  • OR a doctor diagnosed you with mumps in the past
  • OR you were born before 1982.

You or your child will need to stay at home in quarantine and watch for mumps symptoms if

  • You were born after 1st January 1982 AND
  • You cannot prove that you have had one MMR vaccination or mumps infection in the past.

Your date of exposure to mumps was 10th December 2019. 12 days after this date you will need to begin your quarantine period of 25 days. You or your child will need to stay at home away from visitors for this whole 25 days, even if you feel well.

During this time we ask that you or your child stay at home and away from visitors (unless they are known to be immune to mumps). Do not go to school, work, early education centre, church or other public places during this time as you could pass on mumps even if you feel well.

The symptoms of mumps are fever, headache, muscle aches, tiredness, and loss of appetite. The salivary glands on one or both sides of the face, cheeks or jaw may become swollen and sore after two days.

If you develop the symptoms described above, please call Healthline (24 hours) on 0800 611 116, or contact your GP for advice.

Please phone the medical centre or hospital before you go so they can isolate you to prevent the spread of mumps in their clinic. 

Please pass this information on to anyone under 50 years who accompanied you in the clinic.
