A new strain of bird flu that can infect and kill animals has been found in chickens at live poultry markets in China.
Scientists discovered the strain by accident while testing chickens, ducks, geese and other birds for the H7N9 virus that has infected more than 130 people and killed 40 since it was first detected in March.
The new strain, H7N7, poses a potential threat to people, according to lab tests which found that the virus caused severe pneumonia in ferrets, which are used as proxies for humans in flu research.
