Hong Kong health officials say a nine-month old girl has tested positive for a mild strain of the bird flu virus.
Officials said Tuesday that it was most likely the baby was infected when she was taken to a food market that sold live poultry. Doctors have isolated the baby at a local hospital, but say her condition is not that serious.
The head of Hong Kong's Center for Health Protection, Thomas Tsang, says the baby's case is the third time that the H9N2 strain of bird flu has been detected in humans.
Bird flu has many subtypes. The more dangerous H5N1 strain of the virus has killed more than 160 people since 2003.
Bird flu first appeared in Hong Kong in 1997.
The virus killed six people and led to the slaughter of more than a million birds.
