Human Avian flu pandemic risk increases

A flu pandemic similar to the 1918 outbreak which killed 50 million people a year could be on its way to the UK following the discovery of the deadly H5N1 strain across the English Channel.
John Oxford, Professor of Virology at Barts, claims the likelihood of a human avian flu pandemic was "high and within a span of, say, 18 months".
"I'm not alone in thinking that because, again, the World Health Organisation has begged 250 governments around the world - most of which have ignored them - to take this view on and prepare for this outbreak.
"Because what we do not want is either a New Orleans situation or a Tsunami situation - that is you could predict something was going to happen but you don't do anything about it to prepare."
The relatively small number of deaths so far do not mean the current outbreak will not pose a major risk insists Prof Oxford.
Back in 1918 the flu pandemic, which killed 50 million people in a year, also came from a bird in France, and started with just 50 deaths. The similarities are of great concern according to the Professor.
"I still personally find it pretty alarming."
"That is the danger with influenza - compared to any other virus I know - that it can suddenly transform itself, reinvent itself and spread around the world."
Prof Oxford maintained "rather more scientific nations than our own" like Holland can calculate when wild birds were migrating over them and pulled domestic poultry inside.
"That is the sort of thing you can do, in other words biosecurity," he said.
"The reason we are not doing it here, it just escapes me, quite frankly."
The Government have now acknowledged the increased risk, and Ben Bradshaw, the junior minister at the Department for Environment, Food and Rural Affairs, has today warned the public and the poultry industry to remain vigilant.
Poultry keepers have been urged to house birds indoors if needed, and to report suspicious deaths and take bio-security measures following confirmation that a dead bird near Lyon had the virus.
Mr Bradshaw says the Government are taking increased measures, including extra surveillance within the last 24 hours.
He told GMTV's The Sunday Programme: "It's not inevitable but it is clear, obviously, that it's more likely than it was when it was further away.
"The veterinary advice is the risk of imminent infection in the UK is still low but we must remain vigilant."
He added: "We are appealing to poultry keepers to be ready to house their birds should such an order be issued, which would happen if there were an outbreak to be found in this country."
He said that where the disease was discovered in France and Germany was not on migratory flight paths that carried on to the UK, but poultry keepers should monitor their flocks and report suspicious deaths.
"The most important thing is to identify an outbreak quickly," he added.
Defence Secretary John Reid said the Government had taken every precaution necessary.
"The difficulty if bird flu ever transfers to humans - and it hasn't yet so don't let's panic - if it does, up until the point that it does and mixes with human flu it isn't possible to have a vaccine in advance," he told BBC1's Sunday AM.
"It isn't possible to have a vaccine in advance. The most you can do is prepare and have a type of pill you take which diminishes the symptoms after it arrives.
"But it hasn't arrived. Don't let's panic. And I'm sure that the Government has got all necessary measures there."
The announcement in France comes as the disease spread throughout Europe.
In Austria, authorities are ordering all poultry to be kept indoors following strong indications that a wild swan found dead in the capital Vienna would test positive for H5N1.
Germany announced another 28 wild birds had been found to have the deadly strain of bird flu, with hundreds more being tested.
Greece, Italy and Slovenia have also notified outbreaks, and results are awaited on samples from Austria and Hungary sent to the EU's testing laboratory in Weybridge, Surrey.
Outside Europe, India announced its first cases of H5N1 in chickens after 30,000 birds died in the past two weeks in Navapur, Maharashtra and some tested positive for the disease.
Professor Colin Blakemore, chief executive of the Medical Research Council, said bird flu in Britain was not "inevitable".
However, he said: "The risk assessment suggests that certainly the probability is a little higher than we thought a few weeks ago."
Prof Blakemore told ITV1's Jonathan Dimbleby programme there was "absolutely no evidence" that the disease can be contracted by eating infected animals.
"What seems to be required at the moment for these rare human cases seems to be very intimate, close contact between humans and infected chickens," he said.
That meant there was a potential risk to those handling poultry, Prof Blakemore said.
"That would be risk if the infection were to spread to chickens," he said.
Shadow chancellor George Osborne called for a contingency exercise to test Britain's defences to be brought forward from April.
"Given Bird Flu has been discovered in France, on our border, I think and the Conservative Party argues, this should be brought forward," he told BBC1's Politics Show.
"We should test our systems now.
"The other point I make is there needs to be much more public information here.
"There has been some communication with large holders of poultry.
"But there are many people who have small numbers of chickens and things at home.
"A better public information campaign to say this is exactly what is going to happen if we have a Bird Flu case in Britain I think is called for now."
Dr Freda Scott-Park, of the British Veterinary Association, told BBC Radio 4's World This Weekend that "significant amounts of surveillance" were already under way.
"With this new and renewed threat, a bird affected, a duck infected in France, we are going to push the surveillance levels of wild birds up again," she said.
"We are going to have to talk to people on a daily, even an hourly basis, just to see how the situation develops."
Shadow environment secretary Peter Ainsworth said the public needed to know the lessons of Foot and Mouth had been learned.
"If I were in the Government's shoes I'd have armies of advisers and vets and scientists providing advice on what to do and it is not for me to second-guess their judgment," he said.
"What I think is pressing at the moment is a perceived lack of awareness in the public and amongst poultry owners themselves about what might be required were there to be an outbreak.
"And I think the key thing we are looking for the Government to do at the moment is to put right that public information deficit."
Mr Ainsworth added: "The fact is that we are talking about a Government department that has less than a glowing track-record in dealing with outbreaks of animal disease.
"But let's hope that is behind us and that now we have some really clear contingency plans in place and that means knowing in advance, that means being prepared.
"And I think that is where the problem is at the moment. There is a lot of confusion, for example, ministers talk about people bringing birds in doors.
"Well if anyone thinks that taking their chickens into their home is going to be the right thing to do they are sadly mistaken."
Animal welfare minister Ben Bradshaw said there had been a contingency plan in place for three and a half years that had been approved by the Tories and the NFU.
"We are satisfied we have got a good place. We think we have learned the lessons of previous animal disease outbreaks," he told the World This Weekend.
Mr Bradshaw said poultry would only be ordered inside once the disease reached this country.
However, there will be an "urgent review" of arrangements if wild birds are found with the disease on a migratory route crossing Britain.
"Neither of those two conditions is yet met. We don't have an outbreak in wild birds in this country, we don't have an outbreak on a migratory route," he said.
"The secret to this is to identify it quickly, to contain it in one place and then to eradicate it.
"In fact, both the Dutch and the Germans several months ago, back in the early autumn, brought all their birds indoors - we thought rather precipitously - and then a few weeks later had to let them out again.
"Now that caused a great deal of expense, unnecessarily, and a great deal of inconvenience to their industry."
"We think we have got a good plan, it is based on a scientific risk assessment, we are keeping the farmers and the poultry keepers informed and we are also asking the public for help."
Mr Bradshaw added: "We are confident. We aren't complacent but we think we have got a good plan, we think the poultry industry are very well prepared."
