Bird flu subtype re-emerges in Hong Kong: official
HONG KONG (AFP) - An elderly man has contracted a mild form of bird flu in the first case of its type for four years, Hong Kong officials said on Monday.
"We are now investigating a confirmed human case of influenza A H9N2, affecting a man aged 86," Leung Ting-hung, controller of the city's Centre for Health Protection, told reporters.
H9N2 is an avian flu subtype that mainly affects ducks and chickens but can also pass to humans, causing mild symptoms.
Under Hong Kong law cases of such infection must be made public, according to Leung.
