Health authorities have issued a warning after a person infected with the highly contagious measles disease visited Auckland's airport, a mall, and a supermarket.
The Auckland Regional Public Health Service says the person had been overseas and visited multiple busy public locations between May 7 and May 12 and are urging anyone who may have been in contact to watch for symptoms.
The person is believed to have visited:
* Westfield Albany between 5.20pm to 6pm on May 7
* Hobsonville Countdown at about 5.30pm on May 9
* Ferries from Auckland City to Hobsonville Point at 6.15pm on May 8 and 5.15pm on May 10
* A ferry from Hobsonville Point to Auckland City at 8am on May 10
* Auckland Airport domestic check-in and departure lounge from 3pm to 5.30pm on May 12
Medical officer of health Josephine Herman said anyone who needed to get to a doctor should call before visiting.
"Please don't just turn up at the doctor's as you could infect people in the waiting room," she said.
"Just being in the same room as someone with measles can be enough to catch the infection."
It usually takes 10 to 14 days for someone who has caught measles to start showing symptoms with anyone infected at the locations identified above likely to start developing symptoms from May 17 to May 26.
People born before 1969, or who have had measles, or received two doses of the measles, mumps and rubella vaccine, known as MMR, after their first birthday, are considered immune.
Usually about one in 10 people with measles are hospitalised but the rate of hospitalisation for recent measles outbreaks in Auckland is nearly double that.
Measles usually begins with a high fever, runny nose, cough and sore red eyes, followed by a rash starting behind the ears and spreading to the body a few days later.
