Why avian flu hasn't killed us yet

Hmmm... can't truthfully say that I understand much of what they say in this article. But it is pretty reassuring for one who has worried about bird flu. Sugar, Sugar ...

But for the moment, we're okay, it seems like the avian flu doesn't spread easily from one human to another.

And now we know why.

At least, they know why today's form is hard to propogate to and among humans. What they don't know is the likelihood that it will mutate into a form that does transmit easily.
