The original case is an adult who had recently returned from travel to Southeast Asia. The person was not infectious during the return plane trip, but did require hospital admission.
"Two per cent of measles cases are of sufficient severity to warrant hospitalisation, while up to 30 per cent will suffer other complications, hence our efforts to contain spread."
Public Health listed the locations and times at which the measles case was present:
• K Road City Travellers Hostel, Karangahape Rd, August 8-13
• Zarbo deli & café, Newmarket, August 10, 2.30-5pm and August 11, 9am-2pm
• The Auckland City Doctors waiting room, Queen St, August 9, 10am-1pm
• Auckland City Hospital adult emergency department waiting room August 13, 7am-1pm.
Visitors to those places at the listed times were likely to have been exposed to the virus and if not immune could fall sick with measles.
People were considered immune if they had received two doses of the measles vaccine, had had measles disease or were born before 1969. Those who had received only one dose of the vaccine should see their doctor for a free second dose, Public Health said.
Those infected were likely to experience symptoms from seven days after exposure to the virus. The first symptoms are a fever, and one or more of a runny nose, cough and sore red eyes. After a few days a red blotchy rash starts on the face and spreads to the rest of the body.
People who felt unwell and had visited the listed places at the times stated were urged to phone their doctor - or Healthline on 0800 611 116 - for advice rather than turning up unannounced because measles is so highly infectious and could easily spread to others in a medical waiting room.
