Reuters NEW DELHI - A woman in Taiwan has become the first person in the world with a confirmed case of a new strain of bird flu, adding to a growing body of evidence of the potential threat from animal viruses that mutate to be able to infect people.
Scientists from Taiwan said the infection - with a bird flu strain called H6N1 - appeared to be one isolated human case and probably posed little threat for the moment. But it showed how this virus, like others in the past, had been able to acquire genetic changes allowing it to jump across species.
Another new strain of bird flu, called H7N9, is continuing to infect and kill people in China after it first emerged in humans there earlier this year.
