Virology lecture #23: Emerging viruses

only a matter of time H5N1 comes to the Western Hemisphere ?

But we have separate evolution of avian influenza in the American and Eurasian world
since at least ~100 years. The viruses usually don't mix.
In fact, that rare mixing may produce new pandemic viruses in humans.

how does H5N1 transmit ?

they can't figure it out …
In those chicken farms and turkey farms, they should know it, but once I searched
for it and couldn't find it. Presumably respiratory, chicken breathing, but I'm not sure.
——————————————————
it goes back from chickens to wild birds ?

yes, but I assume it's rare. And then it's no longer waterborn as the original
flu in mallards and other waterfowl. It goes to usual species like geese,swans
