Dr. Anthony Fauci, director of the National Institute of Allergies and Infectious Diseases, says the MIT reports are "important evidence" of how the flu viruses are evolving. "However, that is not the entire story, at all, of how viruses evolve in a way to have sustained transmission," he says.
Fauci says what makes animal flu viruses highly contagious among people is complex and poorly understand. "In fact," he says, "I'm not even sure what the extent of the complexity is."
"I've been doing emerging infections for a very long period of time," Fauci says. "And we usually have one on the radar screen, and occasionally two. But to have three on the radar screen, at least in my experience, is pretty unique."
