Officials with Yunnan Provincial Health and Family Planning Commission announced (computer translated) a confirmed case of H9N2 avian influenza in a Mengzi City boy.


Confirmation of the virus was made by the Chinese Center for Disease Control and Prevention via a nucleic acid assay.

The 10-year-old child was treated for the infection and has recovered.

This is the second human H9N2 avian influenza in the past week-the Health and Family Planning Commission of Guangdong Province (Computer translated) reported a case last week in a 29-year-old female patient from Zhongshan City.

In most human cases of avian influenza A(H9N2), the associated disease symptoms have been mild and there has been no evidence of human-to-human transmission. Influenza A(H9N2) viruses are enzootic in poultry populations in parts of Africa, Asia and the Middle East.

Most human cases are exposed to the A(H9N2) virus through contact with infected poultry or contaminated environments. Human infection tends to result in mild clinical illness. Since the virus continues to be detected in poultry populations, further human cases can be expected.
