An 11-year-old girl has died from bird flu in Cambodia in the country's first infection since 2014.
Bird flu, also known as avian influenza, normally spreads in poultry and wasn't deemed a threat to people until a 1997 outbreak among visitors to live poultry markets in Hong Kong.
Most human cases worldwide have involved direct contact with infected poultry, but concerns have arisen recently about infections in a variety of mammals and the possibility the virus could evolve to spread more easily between people.
