The H5N1 bird flu virus could change into a form able to spread rapidly between humans, scientists have warned. <\/p>\n
Researchers have identified five genetic changes that could allow the virus to start a deadly pandemic. <\/p>\n
Writing in the journal Science, they say it would be theoretically possible for these changes to occur in nature. <\/p>\n
A US agency has tried unsuccessfully to ban publication of parts of the research fearing it could be used by terrorists to create a bioweapon. <\/p>\n
According to Prof Ron Fouchier from the Erasmus Medical Centre in the Netherlands, who led the research, publication of the work in full will give the wider scientific community the best possible chance to combat future flu pandemics. <\/p>\n
\"We hope to learn which viruses can cause pandemics and by knowing that we might be able to prevent them by enforcing strict eradication programmes,\" he told BBC News. <\/p>\n
He added that his work might also speed the development of vaccines and anti-viral drugs against a lethal form of bird flu that could spread rapidly among people. <\/p>\n
The H5N1 virus has been responsible for the deaths of tens of millions of birds and has led to hundreds of millions more being slaughtered to stop its spread. <\/p>\n
