Bird flu virus mutating into human-unfriendly form

Bird flu virus mutating into human-unfriendly form - Yahoo! News
"The H5N1 bird flu virus has mutated to infect people more easily, although it still has not transformed into a pandemic strain...The changes are worrying, said Dr. Yoshihiro Kawaoka of the University of Wisconsin-Madison...Birds usually have a body temperature of 106 degrees F, and humans are 98.6 degrees F usually. The human nose and throat, where flu viruses usually enter, is usually around 91.4 degrees F..."So usually the bird flu doesn't grow well in the nose or throat of humans," Kawaoka said. This particular mutation allows H5N1 to live well in the cooler temperatures of the human upper respiratory tract."

Here's hoping world leaders don't lose their focus on this...
