A mumps outbreak has worsened across Auckland. Nearly 500 cases of the highly infectious disease have been registered this year and numbers surged in the past month.

Experts blame flagging vaccination rates for the outbreak and urge parents to ensure children’s immunisation are up to date.

As of yesterday, 457 confirmed and probable mumps cases had been reported to the Auckland Regional Public Health Service. Last year, only 13 cases were reported throughout the city.

The number of cases has ballooned this month to 157 since early September when the public health service announced there had been 300 cases.

Most of the cases were in West and South Auckland.

Otago University public health Professor Michael Baker said the numbers reported were likely to be “only a fraction” of the people who had mumps.

A high number of children were often hospitalised during a mumps outbreak, but it could be a mild illness for others who would not bother going to see a doctor, he said.

Low income people were also less likely to go to a doctor and be counted when it came to infectious diseases like mumps, he said.

Manurewa High School was just one of the schools affected by the outbreak.

The school’s business manager Julie Lockie said six or seven students had contracted the mumps this term, and one new case was reported this week.

She said students who tested positive for the mumps stayed away from school until they had recovered.

The school had sent information about the disease to parents and was encouraging them to ensure children were up-to-date with their immunisations.

Health service clinical director Dr Julia Peters said the outbreak was being fuelled by low immunisation rates. About 80 per cent of those who had contracted the disease not fully vaccinated.

Children are vaccinated against measles, mumps and rubella at 15 months and four years. In the year to June, 88 per cent of 5-year-olds were vaccinated.

Peters said most mumps cases this year were people aged between 10 and 29 years.

A cluster of schools in West Auckland were also at risk of a whooping cough outbreak, according to the health service.

Several students at Laingholm Primary School had been affected, causing the school’s production to be called off.

Medical officer Dr Michael Hale said the outbreak was localised in two small clusters.

“In the past month, we’ve had 33 new cases. It’s one of these infectious diseases that waxes and wanes and we don’t ever really get rid of it in New Zealand.”

Laingholm Primary School principal Martyn Weatherill said several students, parents and siblings had been affected, and new cases continued to be reported.

Across the country, 143 cases of whooping cough, also known as pertussis, were notified between August 19 and September 15 – a significant increase on the 74 cases reported in the same period last year. For the year to September 15, 938 probable, confirmed and suspected cases have been reported.

Dr Michelle Conning from the Titirangi Medical Centre said about a third of the students at Laingholm Primary were not immunised, which was a huge concern to her.

“At the moment we’re definitely dealing with whooping cough but, with our low immunisation rates, it’s probably not long before this happens with a more serious illness.”

Lack of access to vaccinations was not the problem in the area, she said. Rather it seemed to be pockets of people who were anti-vaccination.

The low immunisation rate in the area was a large part of the reason outbreaks often hit the area hard, she said.

Hale agreed areas with less coverage often tended to feature more frequently in outbreaks.


  • Mumps is a serious and highly infectious viral disease prevented by the measles-mumps-rubella (MMR) vaccination.
  • Mumps is spread from an infected person by saliva or mucous droplets when coughing, sneezing or talking. It can be spread via face to face contact within a metre, or by touching an object infected from saliva and mucous, such as a used tissue or keyboard.
  • Early symptoms include 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.
  • Some people can develop rare complications such as pain and swelling in the testicles or ovarian inflammation.

Whooping cough (Pertussis)

  • Whooping cough is a serious and highly infectious disease and is spread by direct contact with fluids from the nose or mouth of infected people.
  • Young children, especially babies under 12 months, and people with weak immune systems (immunocompromised) can become very ill and occasionally die from whooping cough.
  • Whooping cough begins with a runny nose, fever and a dry cough, which develops into long coughing attacks. In babies and young children, coughing attacks often end with a “whoop” sound when breathing in, or with vomiting or gagging. Babies can have trouble feeding or breathing.
