New Zealand measles outbreak climbs to 50

A measles outbreak in Auckland, New Zealand, has infected 50 people, with the number of confirmed cases expected to rise.

The Auckland Regional Public Health Service said that of the 400 people contacted in connection with the outbreak, not counting schools, 200 have been assessed as immune to the disease and do not require quarantine, according to

"These new cases have been in several early childhood centers and we are now working with those centers to quarantine susceptible contacts at home in case they develop measles," Dr. Richard Hoskins of the ARPHS said, reports.

Hoskins said that the 200 others either do not know their immunity status or are not immune.

"Both of these groups need to stay in quarantine, either until after the risk period of 14 days since last contact with an infectious person or until a blood test shows they are immune,” Hoskins said, according to "We strongly advise all children receive two doses of the MMR (measles, mumps, rubella) vaccine at 15 months and four years. We also strongly advise catch-up vaccinations for adolescents and adults who have either none, or only one dose of the MMR vaccine - particularly if they are intending to travel overseas."

The current outbreak has been connected to an unimmunized child who attends school in western Auckland and a passenger who was suffering from the early stages of infection on a Thai Airways flight that landed in the city on June 19.
