A Perth man has become the first person in Australia to contract a strain of swine flu which is resistant to the antiviral drug Tamiflu.

WA Health confirmed the 38-year-old man, who has a weaken Australia to contract a strain of swine fled immune system, initially responded to the drug but developed a resistant strain of the virus when his illness relapsed.

There have been 13 cases of Tamiflu-resistant infections reported around the world.

WA’s Chief Health Officer Dr Tarun Weeramanthri said in a statement this was a rare and isolated case and did not pose a risk to the public.

“There is no evidence that the virus has spread to other people – none of the patient’s family or hospital staff caring for him have contracted the virus, and he has not been in contact with the wider community,” he said.

“Experience from overseas shows us that these cases tend to be confined to individual patients and it is not uncommon for it to occur in people who have weakened immune systems.”

Dr Weeramanthri said the man had been treated with an alternative antiviral drug that was active against the resistant virus and was no longer infectious.

However, he remains in a critical condition in intensive care.

“When it becomes available, the human swine flu vaccine will offer the best protection against the virus and I would encourage people to seriously consider getting vaccinated,” he said.

The first people to be offered the vaccine will be pregnant women in their second and third trimester, those with underlying medical conditions including morbid obesity, Aboriginal people, children in special schools and frontline healthcare workers, WA Health said.

About 200 students at an exclusive boys school have been told to stay home as 10 new cases of swine flu have been confirmed in Western Australia.

The WA health department said the latest cases – ratified on Sunday – lifted the number of confirmed cases in the state to 14.

On Saturday, the department reported that an 11-year-old boy from Scotch College and a 23-year-old woman who had visited Melbourne tested positive and were in home quarantine.

Of the 14 cases, nine are children, communicable disease control acting director Paul Effler said.

The nine children, all aged about 11, are at three Perth schools including six at Scotch College, two at Christ Church Grammar School and one at East Claremont primary school, all in Perth’s affluent western suburbs.

“We’re now working with schools to discuss the best course forward,” Dr Effler said.

“We’re recommending partial closure or in the case of a small school closure for a limited time.”

Scotch College acting headmaster Peter Freitag said about 200 students in years six and seven would stay home this week.

“We’ve been advised to go for a week,” Mr Freitag said.

No one infected with the virus in WA has been hospitalised and all were on their way to a full recovery from the virus, Mr Effler said.

WA’s only confirmed case of swine flu has been cleared after a week in quarantine, Ten News has reported, while the nation’s swine flu tally has passed 400.

The  man, who tested positive last week after going to hospital with mild flu symptoms, was in home quarantine with his wife and their eight children.

Australia’s Eastern States has been particularly hard-hit by the flu and Victoria has recorded a massive surge in cases, most of them children.
 
By this afternoon the number of confirmed cases in the State had risen to 306, a rise of 94 in 24 hours.

Most of the new cases in Victoria also involved young people aged five to 18, prompting a twelfth Victorian school to be closed today.
 
According to Federal Health Department figures, there were 64 confirmed cases in NSW, 18 in Queensland, six in South Australia, four in the ACT, and one each in Tasmania and the Northern Territory.
 
However, Queensland Health officials say the State now has 22 confirmed cases, the latest being teenage girls.
 
Federal Health Minister Nicola Roxon said the Government was assessing whether to elevate the nation’s response to the disease from the contain to the sustain phase.
 
Victoria is already preparing to move into the sustain phase, under which quarantining is limited to those who share a home with a confirmed swine flu patient.
In the contain phase, anyone who has had contact with a swine flu patient is quarantined voluntarily and given antiviral drugs for a week.
 
The nation’s chief medical officer, Professor Jim Bishop, said the advice to people with flu-like symptoms may change as swine flu evolved.
 
At present, people who come down with flu-like symptoms, especially if they have recently travelled to an affected country, are being advised to seek medical advice.
 
Professor Bishop said in the future, fit and healthy people may be told to stay at home and only those in at-risk groups, including those with seek medical advice and asthma, will be advised to visit their GP.
 
“A lot of people that have these sorts of symptoms of course will, as this thing progresses, stay at home and not necessarily seek medical advice if in their own case it is a at-risk groups— and that we expect to see more of,” he said.
 
“As we move along in this marathon race, what we will need to do is obviously identify those people that we’re concerned about.
 
“If there is large numbers involved, we want to make sure the system is looking after people we most want to look after.”
 
The swine flu-affected ship Pacific Dawn docked in Sydney this morning after NSW Health authorities gave it the all-clear.
 

The P&O ship was forced to cut short its trip to the Barrier Reef last week when three crew tested positive for the virus.
 
A senior NSW Health doctor and 25 nurses boarded the ship in Brisbane on Saturday, testing all 2500 people on board during the two-day voyage to Sydney.
 
While disappointed the cruise didn’t go to plan, passengers said they still enjoyed the journey.
 
David Geers, from Brisbane, joked it was the perfect place to be quarantined for seven days.

 “If you had to be quarantined somewhere I couldn’t have thought of a better place … because we got fed, the drinks tasted the same and the staff were fantastic,” he told reporters at Darling Harbour.
 
More than 15,000 people in 53 countries have tested positive to swine flu, with deaths totalling 99.
