Girl, 17, is killed by bird virus.
The 17-year-old girl is among 49 people across South East Asia who have been killed by the virus since 2003.
World health chiefs fear a worldwide pandemic of the virus which has spread from birds to man.
A 40-year-old woman in Vietnam is suffering from the most deadly form of the virus which doctors fear could mutate into a more contagious version.
The disease kills around 70 per cent of the people it infects.
One family of five in Vietnam who have been infected have had all their poultry slaughtered to stop further outbreaks.
Experts are no longer talking of wiping out the disease, but of containing it before it mutates.
