Avian influenza: H5N1 detected in pigs in China
20 August 2004
A researcher from Chinas Harbin Veterinary Research Institute has today presented initial evidence that pigs from farms in parts of China have been
infected with the H5N1 strain of avian influenza. The findings, set out in a table and without further supporting data, were presented today at an

WHO has requested confirmation and further details about this study.

In order to assess the implications for human health, it is important to know whether the reported infections in pigs are rare events, possibly caused

without developing symptoms, and are known to excrete large quantities of the virus in their faeces.
