At a press conference currently underway, health officials confirmed a total of 13 people from the Rangitoto College group that returned from Mexico at the weekend had now tested positive for Influenza A – an increase of two – and all probably had swine flu.There were 31 suspected cases around the country but many more people in isolation as a precaution. Three had been confirmed as having swine flu so far and further results were awaited.
Dozens of other passengers who shared Air New Zealand flight NZ1 from Los Angeles with the infected pupils remain in quarantine and are yet to be tested. So far the isolation cases include 37 in Christchurch and 36 in Wellington.
Meanwhile, two women with suspected flu symptoms have been detained by health officials after arriving at Auckland Airport this morning.
“On the basis of these results we are assuming that all of the people in the group, who had tested positive for Influenza A, have Swine Flu,” a Ministry statement said.
Two women with suspected flu symptoms were detained by health officials after arriving at Auckland Airport this morning.
An Auckland Regional Public Health Service official said the two arrived on a Qantas flight from Los Angeles early this morning.
More details are expected later this morning.
They have been taken to Middlemore Hospital and will be tested for swine flu. .
Thousands of New Zealanders may have been exposed to the deadly swine flu virus as a result of a three-day delay in alerting health boards to potentially infected people.
Health officials are investigating a further 43 cases of possible swine flu – this figure has been revised down from 56 following further investigations yesteterday. Spain’s health minister has confirmed a second case of swine flu, while Israel also confirmed one case.
Officials have admitted they did not send swabs taken from the 11 pupils for testing till Monday night, missing a flight to Melbourne as a result of delays in packaging the samples.
As confirmation of the outbreak emerged, the Government faced criticism for its response to the crisis.
Another member of the school group tested positive for influenza A yesterday.
The Government has now moved from trying to contain the outbreak to attempting to minimise it.
He said he was shocked at the test results, “even though it was a possibility”.
Rangitoto College principal David Hodge said most of the school party, which visited Mexico on a three week trip, had recovered with only one student, who already suffered from asthma, still unwell.
Officials did not plan to update New Zealand’s health alert code from “yellow” to “red” following the positive results.
But Auckland Regional Public Health officials said the families of the swine flu-infected had taken the news well.
Dr Jacobs said the general public did not need to worry as officials were working to contain the spread and those with confirmed swine flu had so far experienced mild symptoms.
Dr Jacobs said the general public did not need to worry as officials were working to contain the spread and those with confirmed swine flu had so far experienced mild symptoms.
“There is no indication it is any more or less contagious than any other form of influenza,” he said.
It was most contagious a day before symptoms appeared and up to seven days after. The greatest risk was in the early days.
All but 18 of the 356 people on board flight NZ1 have now been contacted, offered Tamiflu and been asked to stay in voluntary home isolation.
Auckland doctor Jim McVeagh, who works at a private accident and medical clinic, said everyone should have been contacted immediately it became apparent passengers had symptoms of the deadly swine flu.
Dr McVeagh treated a patient on Monday from the same flight as the infected pupils. She had rung Health Line and been told to visit her doctor “one of the most spectacularly bad pieces of advice” he had heard.
“I am hoping this isn’t a big deal, because we’ve probably already missed the boat with containment. I think the Health Ministry has been a bit tardy, a bit relaxed.”
Reports of the outbreak began emerging from Mexico on Thursday. But there were no plans to screen passengers arriving from North America till the Rangitoto pupils showed symptoms.
Auckland Regional Public Health clinical leader Julia Peters defended the response time, saying health authorities could not act till they knew what they were dealing with.
“As soon as we got a provisional diagnosis we swung into action and began contacting people …”
She said test samples were not sent to a specialist lab in Melbourne before Monday because they required special preparation and packaging.
The Health Ministry’s emergency planning co-ordinator, Steve Brazier, said initially Auckland authorities were doing all the contact tracing. “However, when the size of the task was appreciated on Monday a decision was made to refer potential cases from Flight NZ1 to regional public health units around the country to follow up in their area.”
The Government has upgraded it travel advisory warning to Mexico, warning of a high risk to health and advising against all non-essential travel.
Health Minister Tony Ryall dismissed criticism yesterday, saying the initial response had been rapid, thorough and appropriate for the level of risk at the time.
“This is a threat New Zealand has planned for. Many of the best people in the health service are working night and day to protect the health of New Zealanders.”
The World Health Organisation has raised its pandemic alert level to phase 4, indicating significant increased risk of a pandemic a global outbreak of a serious disease.
