The bird flu is not known to go from person to person ,,yet.
There are limited cases of person to person transmission, there's a link to the New England Journal of Medicine article earlier on this thread.
I posted a link to the CDC information and a couple of paragraphs.
Some don't think this constitutes "proof" of h2h transmission, but it is certainly strongly suggestive of a beginning of h2h in a limited way.
Please check my post #215. It is not spreading easily, but it is spreading person to person.
Unless you are willing to go through the most confounding and obtuse conversation you have ever had, you would be well advised not to engage these people on their fantasy.
To them, conjecture is proof. All of the sources they cited stated clearly and unambiguously that there is no proof, only expectations. Yet, they still claim you are wrong AND their sources are wrong.
The argument goes like this; here is my source, and his statements prove me wrong,,,so I am correct.
It's amazing.
And you thought only liberals were illogical.....:^}
