Cell barrier shows why bird flu not so easily spread among humans

>Viruses isolated from humans infected with avian flu can thus be monitored in a way to provide more advance warning of a potential pandemic.

"Identification of H5N1 viruses with the ability to recognize human receptors would bring us one step closer to a pandemic strain," says Kawaoka. "Recognition of human receptors can serve as molecular markers for the pandemic potential of the isolates."
