WHO confirms five deaths from China bird flu

The World Health Organization says there have now been five deaths in China from a new bird flu virus.

There have been 11 laboratory-confirmed cases of the H7N9 virus, a form of avian flu which had not been seen before in humans.

But the WHO says there is currently no evidence of human-to-human transmission of the virus.

Tests suggest that the virus could be treated with the anti-influenza drugs Tamiflu and Relenza.

Around 400 people who have been in close contact with the 11 cases are being monitored.
