There are now 109 confirmed cases of swine flu in New Zealand with 23 of them coming in the last 24 hours.
Of the 23 latest cases, seven cases are in Auckland, three in Wellington and 13 in Christchurch.
The Ministry of Health said that while the number of cases was increasing, there are still relatively few cases and only isolated instances of community transmission.

SWINE FLU PARTIES
Meanwhile the Health Ministry has warned against hosting “swine flu parties” following overseas concerns parents are deliberately exposing children.
The public interest in swine flu had been significant with 1500 calls answered at Healthline yesterday, almost double the usual amount. That person contracted swine flu after visiting Victoria, Australia in early June.
The Canterbury District Health Board said all cases of the influenza A (H1N1) strain stemmed from a single case.
The trend has prompted the Australian government to warn against swine flu parties gatherings where people intentionally expose themselves to the flu, in order to become infected with the virus.
Meanwhile, media reports in Australia and the United States say some parents have intentionally exposed their children to swine flu, believing that infecting them now will save them from a potentially more virulent strain in the future.
New Zealand’s deputy director of public health Dr Fran McGrath said the tactic went completely against the Health Ministry’s efforts to contain the virus. The idea has also been panned by health experts here.
She said that if people deliberately made themselves ill this would have a huge impact on already-stretched health services.
“The reason we’re doing [containment] is because this is a brand new virus to which people don’t have immunity so there will be lots of people who get it,” she said.. “.swine flu parties are definitely not part of our public health advice..
“We don’t know what the nature of the mutation would be.”
There was also no guarantee that getting sick now would lead to immunity in the future.”"It may give you some [immunity] but we can’t be sure about that. If there were to be a second wave then it would be as a result of a mutation in the virus and you can’t tell how big that mutation might be and therefore how useful any immunity from an earlier version would be.
According to the Centers for Disease Control and Prevention in United States, people hope to become affected from the mild form of the virus, in the hope of having natural immunity to a more virulent form that might circulate later.”
The concept appears to have stemmed from chickenpox parties where parents would deliberately infect their children in the knowledge the virus was less serious in children than adults. I understand the thinking, but I just fear we don’t know enough about how this virus would react in every individual. I understand the thinking, but I just fear we don’t know enough about how this virus would react in every individual.
“This is like the Middle Ages, when people deliberately infected themselves with smallpox. It’s vigilante vaccination you know, taking immunity into your own hands. .
All cases stemmed from a single person who had been in Victoria, Australia in early June and contracted swine flu.
All those affected were being treated with Tamiflu and recent contacts were being traced.
The cases included six pupils from three schools in Christchurch’s eastern suburbs, and a Minister in a Samoan Church who worked at Christchurch Hospital in the catering team.
A Christchurch seafood processing plant has also sent home all its factory staff after a second case of swine flu was discovered there.
Sea Products in Woolston sent home night shift workers yesterday after one staff member caught swine flu, but now the day shift has also been quarantined for three days with antiviral drug Tamiflu after a second case was confirmed.
The 100 workers will all be back to work by Friday.
“The catering team member had not been to work during the infectious stage of the illness,” Canterbury medical officer of health Alistair Humphrey said.
Swine flu was a highly contagious disease, he said.
“Once someone who is infected is amongst other members of the community, including students and workmates, it is inevitable others will get sick,” he said.
While most people do not become seriously unwell, the virus’ potential effect on businesses, schools and the community was starting to show itself, Mr Humphrey said. In East Auckland primary school St Patrick’s, in Panmure, yesterday sent all of its 145 pupils home for a week after having one confirmed case of swine flu, and a number of others suffering flu-like symptoms.
Bromley School in Christchurch has been closed for seven days by health officials to prevent the spread of swine flu.
A recorded message on the school’s phone said all families would be contacted by the weekend with further information.
“Huge apologies for the disruption to family life,” the message said.
The primary school has 320 pupils.
Other Auckland schools were also hit.
At Kowhai Intermediate, in central city Kingsland, one class of year eight students and a teacher were in quarantine.
Papatoetoe High School in South Auckland has one swine flu case, while on the North Shore at Westlake Girls’ High School some 450 year 12 students are away for a week, after one case.
Health Ministry planning was to enable health services to manage large numbers of cases as well as maintain services for those who most need them, Dr McGrath said.
“An important part of this approach will include advising individuals how to look after themselves at home where this is possible – in the same way they would with seasonal flu.”
Swine flu may be serious for some people and they should seek advice either from Healthline 0800 611 116 or their GP – but phone ahead first.
The new confirmed cases yesterday were in Auckland (two), Rotorua (one), Tauranga (two), Wellington (five) and Christchurch (five).
STOP THE SPREAD
The ministry has refined advice to arriving international travellers – only people with flu-like symptoms within four days of travel were now considered to be at risk of swine flu.
Workers should stay home only if they have flu-like symptoms or if they have had medical advice, the ministry said.
They should stay home for seven days after symptoms begin, or until symptom-free for 24 hours, whichever is longer.
This was to keep them from infecting others.
Hand hygiene was still the most effective protection – wash hands with soap and water and dry them thoroughly, the ministry advised.
Alcohol-based cleaners were also effective, and people should avoid touching their eyes, nose or mouth, as germs spread this way.
The Ministry of Health has moved its response to phase 6.2 which means restrictions could be placed on public gatherings and a state of emergency could be declared. It is the last phase before code red.
