...epidemic of avian flu hit eight Asian countries, killed at least 23 people and led to the death or culling of more than 100 million chickens-and that could be just the prelude. Last week China, Thailand and Vietnam all announced that they had chickens infected with the virulent H5N1 virus that causes avian flu, dashing hopes that the bird culls earlier this year had eradicated it. Officials in China appear to have responded quickly, barring the export of poultry from the affected Anhui province and culling 30,000 birds within a three-kilometer radius of the original infection. Thailand...
...research studies warn, however, that widespread human infection may be only a matter of time. A report published in Nature last week by scientists at the University of Hong Kong and Shantou University shows that the H5N1 virus has evolved rapidly since it first infected humans in Hong Kong in 1997, killing six. The result was the powerful strain of H5N1 that caused this winter's unusually widespread and lethal outbreak. Another recent study shows that the latest strains of the virus proved the most deadly to lab mice-raising worries that H5N1 is also becoming increasingly dangerous to humans...
...real fear is that H5N1 could crossbreed with a standard human-flu virus to create a highly lethal, highly contagious strain with the potential to cause a global flu pandemic. Professor Yi Guan of the University of Hong Kong, the lead researcher on the Nature paper, worries that H5N1 is evolving so fast that it may gain the ability to infect humans by mutating on its own, without mixing with a human virus, much as SARS did. Yi says the latest outbreaks show that the virus has become endemic to the region, with a difficult-to-eradicate foothold in migratory...

...winter's lethal outbreak. Professor Yi Guan of the University of Hong Kong worries that H5N1 is evolving so fast that it may gain the ability to infect humans simply by mutating on its own. "We must face the problem, not avoid it," says Yi - or the problem will face us soon enough. - By Bryan Walsh. With reporting by Matthew Forney Sentence Shelved SWEDEN A Stockholm appeals court overturned the life sentence of Mijailo Mijailovic, the convicted murderer of Foreign Minister Anna Lindh, ruling that he should instead be sent to a psychiatric unit for treatment. The court upheld...
