Avian influenza: H5N1 detected in pigs in China.

20 August 2004
A researcher from China�s 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 international symposium on SARS and avian influenza held in Beijing.

WHO has requested confirmation and further details about this study.

Pigs are known to be susceptible to infection with avian influenza viruses. However, natural infection of pigs with the H5N1 strain has not been previously reported.
