Just came across this tidbit of info that was new to me ....
Avian flu is often carried by waterfowl and migratory birds (hence the name), but most strains of the flu don't actually get the birds sick.
Not true with H5N1 though. The H5 strain is highly pathogenic and thus birds with the virus die before making it from the eastern hemisphere.
The H5 strain has not reached North America, South America, or Australia to date. It COULD happen by smuggling.
