The person who attended the Basketball New Zealand Under 15 Nationals competition infected with measles was not local, but health authorities are urging people to stay vigilant.

Toi Te Ora Public Health is urging anyone who attended to be vigilant for the symptoms of measles after a participant took part while unknowingly infectious with the highly contagious disease.

Team members, family, staff and other spectators who attended the tournament may have been exposed to measles at the competition which was held at Trustpower Arena in Mount Maunganui from July 17 to 20.

Medical officer of health Dr Neil de Wet said the person was not local but there was a risk of measles spreading in the community.


"It's inevitable that we will have these cases with people travelling," he said.

"Measles is highly infectious and spreads easily from person to person."

He said there had been no confirmed cases of a Bay of Plenty resident having measles since June 12 and Basketball New Zealand had put out an alert about the incident.

It can take from seven to 14 days after exposure to start developing symptoms and therefore de Wet said anyone who was not immune and attended the tournament should be on the lookout for the symptoms of measles from July 24 until August 3.

The early symptoms of measles include fever, cough, runny nose and sore red eyes, and this is followed a few days later by a red, blotchy rash, usually starting on the face before moving down the body.

Measles is infectious to others from when the early symptoms start, even before the rash appears.

If you think you or someone in your family may have measles, it's important to stay at home and phone your doctor to alert them to your symptoms, and allow them to make arrangements to assess you safely and without infecting other people.

You can also call Healthline on 0800 611 116 for advice.


De Wet pleaded with people to not turn up to their doctor, after hours or emergency department without first phoning ahead, as they could potentially infect others in the waiting room.
