Warmer climes in the northern hemisphere might not mean anything to the deadly H5N1 virus as was earlier thought, due to its deep penetration in the poultry flocks in several parts of Asia, according to health experts.
Scientists had suggested earlier that the activity of the bird-flu virus would indeed be pronounced during the months from October to March when temperatures are below 20 Celsius, but there seems to be no respite in its spread, despite the onset of summer.
The numbers of human infections remain low at 204 cases, with 113 deaths. Experts have raised caution that the virus requires only a few mutations to magnify into pandemic proportions.
According to experts, a lower rate of the virus is not an indication of its weakness. The highest threat is still chicken and not wild birds, because the cases where humans have been affected have occurred in the areas close to poultry outbreaks, except in the case of china. It is imperative to adopt quick mass culling in areas with outbreaks and administer vaccination for poultry in surrounding areas.
