Beijing, China: China has confirmed the first known human case of the H3N8 strain of avian flu, but health authorities say there is a low risk of widespread transmission among people.
H3N8 is known to have been circulating since 2002 after first emerging in North American waterfowl. It is known to infect horses, dogs and seals, but has not previously been detected in humans.
China's National Health Commission on Tuesday said a four-year-old boy living in central Henan province tested positive for the strain after being hospitalised earlier this month with a fever and other symptoms.
