"Since you seem to be quite knowledgeable about this, any idea why these flu strains seem to originate in China most of the time?"

Seems to me that I'd heard many of these viruses originate with chickens (?) and that many in China are allowing these animals to live in their homes thus spreading the virus from animal to human. Anyone knowledgeable enough to elaborate on this?

There's a waterfowl-swine connection in China. iirc, the viruses originate with the waterfowl, spread to the swine, thence to humans in China.

But I could be mistaken.
