    Influenza A (H9N2) infection in a 5-year-old boy -- Cases in 1999.

    Wednesday, December 10, 2003, 09:10 EST (9:10 AM EST)


    On December 9, 2003, CDC received information from the Hong Kong Department of Health indicating preliminary laboratory evidence of influenza A (H9N2) virus infection in a child in Hong Kong last month. The boy had been admitted to a local hospital on November 27 and was discharged 2 days later. The Hong Kong Department of Health is conducting follow-up studies.

    At this time, CDC does not recommend any changes in current U.S. influenza surveillance protocols. There is no information to indicate that there is an outbreak of H9N2 infections in Hong Kong or spread of these infections elsewhere. However, if laboratories identify an influenza A virus that cannot be subtyped, the CDC Influenza Branch should be notified immediately at 404-639-3591 to arrange for further testing. The statement from the Hong Kong Department of Health is as follows.
