A confirmed case of measles in a participant in last weekend's charity Sky Tower climb has public health officers racing to trace hundreds of people who may have been exposed.
A participant who stayed at SkyCity hotel over the weekend of May 22 to 24 and participated in the Firefighter Sky Tower Stair Challenge developed measles symptoms after returning home to Palmerston North.
The Auckland Regional Public Health Service (ARPHS) said anyone who had been in the SkyCity complex, hotel, or stair challenge, as well as a nearby Mexican restaurant between May 22 and May 24, should check with their doctor that they had been immunised against measles.
People who could have been exposed to the virus and were not immunised should isolate themselves at home immediately until June 7, ARPHS said.
Chief Medical Officer Don Mackie said a large number of people from many parts of the country were potentially exposed, and public health units nationwide had been notified.
