Doctors are treating unimmunised New Zealanders in carparks and outdoor areas in an attempt to reduce the spread of measles, as the number of confirmed cases of the contagious disease rose to 25. Growing public outcry over those companies' inaction in response to the spread of misinformation led both Facebook and YouTube to announce concrete steps to address the problem in recent weeks.
"So that's one of the other issues that makes it so perplexing - people who might stay home if they knew they had Measles, don't realize it is Measles until they've already infected other people", Mann said.
Another one or two out of 1,000 people with measles will die, even with medical treatment. Many of this year's cases stem from an outbreak in Washington state, and almost all of those involve children who weren't vaccinated against the disease.
"Immunisation is the only sure way to avoid getting measles", Pink said. Those aged between 29 and 50 will only have had one measles vaccination and are not considered immune.
The DHB said under-immunised people who came within two metres of an infectious person, however briefly, had a 90 per cent chance of contracting measles.
Panic is setting in over the Canterbury measles outbreak as more cases of the untreatable disease emerge. The cases have mainly been appearing among those who were born before 1969 and those who are not fully immunized.
With Canterbury health centers running out of vaccines since the start of the outbreak in late February, 3,000 MMR vaccines have been brought by Sunday and 18,000 more are to be delivered to the region by Wednesday.
New Zealand's Health Minister David Clark on Tuesday urged people to ensure their vaccinations are up to date as more MMR (measles, mumps and rubella) vaccine is sent to Canterbury in the South Island to deal with the ongoing measles outbreak.
