The number of mumps cases is on the rise in New South Wales, with 15 being reported in May alone.
Dr Vicky Sheppeard, director of communicable diseases for NSW Health, said that it was mostly young adults being affected by this recent outbreak.
She has called for everyone to check their immunisation status, especially if they are planning on travelling overseas sometime in the near future.
"Many people in their 20s, 30s and early 40s will not be immune [to mumps]", Dr Sheppeard said in a June 13 statement.
"So it is particularly important they check their status with their doctor and get vaccinated if they are not sure."
She recommends two doses of the MMR vaccine, which – in addition to limiting your chances of contracting mumps – will give you good protection against measles and rubella.
"Children should be vaccinated on time with the MMR vaccine at 12 months and again before they turn four years of age," said Dr Sheppeard.
The government has recently taken a stand on immunisation, making it a requirement for one, two and five-year-old children whose parents collect the Child Care Rebate or Family Tax Benefit.
Michael Moore, chief executive officer of the Public Health Association of Australia (PHAA), has welcomed such measures.
"Immunisation rates in Australia do need to be improved if our children are going to have proper protection from deadly diseases," Mr Moore said.
"There are particular areas in Australia where there are not enough people providing their children with appropriate levels of protection".
If you're concerned about the health and wellbeing of your family, you may want to consider taking out a family health insurance policy.
Prevention is best and getting your children vaccinated can help them avoid becoming seriously ill.
In addition to this, having a private health insurance policy can make sure that your children get the medical attention they need should they ever require it.
Adults, too, should consider getting vaccinated if they haven't been already.
"Mumps can be quite a serious infection for adults," revealed Dr Sheppeard.
It can take two or three weeks to develop after you have been exposed to an infected person. People can be infectious for about a week before and up to nine days after they've experienced swelling of the glands.
