A person diagnosed with measles in Auckland visited several public places while infectious.
Auckland Regional Public Health Service (ARPHS) has urged people who were in the same place as the infectious person to call their GP or Healthline if they have measles symptoms.
Those places were K-Mart and The Warehouse in Manukau Supercentre and the Countdown supermarket at Airport Oaks on April 9, and Middlemore Emergency Department between 7pm on April 12 and 11.30am the next day.
The initial symptoms of measles include a fever, running nose, cough and sore eyes.
After about a week, a raised red rash spreads over the body lasting several days.
Medical Officer of Health Dr Julia Peters said measles was a serious illness and there was no treatment.
