The suspicion is that the problems originated with markets where live animals were kept and animal body parts, as well as seafood.

So a virus jumps from animals to humans.

Isn't that what the bird flu virus was thought to originate from as well, these restaurants in Asia where they kept live poultry?


If it is due to these practices with livestock, why would it originate only from that one city? Seems like a cultural custom so it could be a bigger problem?

Or have they tried to enforce some safer livestock handling practices?
