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.
Since 1999 Hong Kong has reported seven such cases with the last one reported in 2009, Leung said.
The man, who lives in the southern Chinese city of Shenzhen bordering Hong Kong, was diagnosed with the disease after returning to Hong Kong on Saturday.

The male victim had returned from Shenzhen, as had a woman who contracted Hong Kong's first reported case of H7N9. She is still in hospital in stable condition.
