During the winter months avian influenza Technorati Profilehas resurfaced and caused human deaths in Asia like Indonesia and China. As reported by Indonesia mass media that they announced that 115 person death infected by the disease until today. According to WHO the virus has killed 208 people worldwide since it began ravaging asian poultry stocks in late 2003.
As we know that this disease can occur to human by closed contact with sick birds, rather than eating properly cooked eggs or poultry. Scientists say it is impossible to predict what the H5N1 virus will do, but more bird flu outbreaks often occur when temperatures drop as winter sets in. Like the others experts say the change is almost inevitable given the history of other viruses that have "jumped" to people. Viruses, after all, are opportunists -- always swapping genes or mutating as they seek to infect new species. Since viruses can only reproduce inside cells, infection is a matter of ultimate evolutionary consequence for them.
A distinctly new strain like H5N1 can be deadly for two reasons that influenza is highly contagious disease, and people have no immunity to strains they have never been exposed to. No vaccine has found until this time to cure the victim has exposed by this virus type.
