The first case of Influenza infection in tigers was in China 2002

The first finding of tiger influenza by virus isolation and specific gene amplification 22 October, 2004 An influenza virus-like isolate was obtained from specimen of a tiger died of high fever, anorexia and twitch.

Last week both groups were hurriedly trying to get the papers translated.
The findings became widely known only when an author on the papers, virologist Chen Hualan of Harbin Veterinary Research Institute in northeast China, presented them at the International Symposium on the Prevention and Control of SARS and Avian Influenza in Beijing on 20 August. The results, which show that the virus was found in 2003 in pigs in southeast China, were originally published in January (L. I. Haiyan et al. Chin. J. Prev. Vet. Med. 26, 1-6; 2004). Read More
