There is now little chance of people picking up measles following an outbreak at an Auckland firefighter challenge last month, Bay of Plenty health authorities say.
Chief medical officer Dr Jim Miller said the incubation period for measles was over. Fifty-eight local firefighters took part at this year's Sky TowerStair Challenge on the weekend of May 22.
Concern was initially raised when a firefighter participant was diagnosed with measles in the days following the event. The event draws thousands of firefighters throughout New Zealand to Auckland and measles is highly contagious.
"The incubation period is generally taken to be about 14 days [after contraction]," he said.
"We followed up with the firefighters that we were aware of and we contacted them directly at the end of May. There were a few people who requested that they went into quarantine and they are all out now."
The final day of incubation for the outbreak was June 6.
