Thanks for the info.
I've been reading about this flu for some time; learned more about how flus develop than I ever dreamed about. It looks like a guaranteed serious threat. Whether it will devlop the ability to transmit from human to human is the key, most of those who are experts in the field think it will - just a question of when. And if/when it does, it will kill a great many people. Right now the fatality rate as far as they can tell is about 50%. Even if it goes down to 5% that's millions of people.
