Scientists To Re-Evaluate Bird Flu Threat

...The bird flu virus is one of the lethal viruses to infect birds. However, it has not inherited genetic changes that would enable human -human transmission of the disease. So far, the H5N1 virus has not been able to alter its behavior in human beings, reducing the possibility of a sparking a pandemic. This...
