Several mumps cases have been reported at the Fire And Emergency New Zealand National Training Centre in Rotorua.
Toi Te Ora Public Health, the public health service for the Bay of Plenty and Lakes districts, has been notified of the cases.
"Toi Te Ora Public Health has followed up close contacts of these cases and immunisation has been recommended for those who need it," medical officer of health Dr Natasha Murray said.
There is an ongoing mumps outbreak in New Zealand, mostly in the Auckland region.
13 mumps cases have been notified in the Bay of Plenty and Lakes districts in the last month.
"Immunisation with the measles, mumps and rubella (MMR) vaccine is the best protection against mumps – and it also protects against measles and rubella," Dr Murray said.
MMR is recommended and free for anyone born from January 1 1969 and is routinely given to children at 15 months and 4 years of age.
"We strongly recommend that everyone in the Bay of Plenty and Lakes communities checks whether they have received two doses of MMR vaccine. If you're not up to date, please visit your family doctor to get immunised. MMR is free for anyone who needs it," Dr Murray said.
Toi Te Ora Public Health said teenagers and young adults aged 12 to 29 were at greatest risk of catching mumps because, due to changes in our national immunisation schedule, they may not have been fully immunised as children.
Mumps is very infectious and spreads from person to person by coughing and sneezing, or through contact with infected saliva, such as sharing food and drink. If you have caught mumps, symptoms usually appear two to three weeks after contact with someone who is infectious.
Symptoms can include fever, headache and swelling over the cheek or jaw area on one or both sides of the face. It is usually a mild illness that lasts about one week, but can have serious complications.
