Hong Kong's government says two dead birds, a crested myna and a chicken, have tested positive for the H5N1 strain of bird flu.
Authorities say three villagers may have come into contact with the infected chicken, and are being isolated in a hospital. They say the three people are being tested for bird flu, but have shown no obvious symptoms.
The dead chicken was purchased by a Hong Kong villager in mainland China.
The dead myna was found in a playground in an urban area of Hong Kong.
Authorities say they will close a local bird sanctuary and all public aviaries beginning Thursday as a precaution.Some information for this report was provided by AFP, AP and Reuters.
