Uncontrolled bird flu in China has seeded
outbreaks in Vietnam and beyond: study (excerpt) TORONTO (CP) - Genetic analysis of H5N1 avian flu viruses collected from wild and domestic birds in China suggests the virus has spread in uncontrolled fashion in southern China for the past decade, igniting outbreaks in Vietnam on at least three occasions and triggering spread of the worrisome virus across Russia to eastern Europe, a study released Monday suggests. The study also provides what could be a smoking gun in the heated dispute about whether migratory birds are actually playing a role in moving the virus across the globe. A number of wildlife experts have insisted migratory birds are not to blame, but this study contends genetic analysis shows there can be no other explanation. "I've spent most of my life working with wild birds and I'm sympathetic. But you can't hide the facts that wild birds are most probably involved in the spread of this thing now," said leading avian influenza expert Dr. Robert Webster, one of the authors of the paper. Webster and his co-authors - researchers from institutions in China, Hong Kong, Vietnam and Indonesia - argue the only way to minimize the damage done by the virus and reduce the risk it poses to human health is by addressing the problem at the virus's birthplace, in the poultry flocks of southern China. http://www.mytelus.com/news/article.do? pageID=ontario_home&articleID=2163456 Edited by Rick |
