Indonesian officials say a teenager from West Java has tested positive for the H5N1 strain of bird flu.

The Health Ministry said Saturday the 17-year-old is being treated at a local hospital. 

Elsewhere, Cambodia's Health Ministry announced a new outbreak of the H5N1 strain among poultry in the country's southeast.

The ministry said the outbreak was discovered in ducks in a village farm in Prey Veng province.  More than 1,000 ducks have already died, and authorities are culling the remaining poultry to contain the spread of the virus.

Bird flu has killed nearly 140 people since 2003, mainly in East Asian countries.

Health officials are concerned that the virus could mutate into a form easily transmissible by human-to-human contact.
