Is There a Lab to Explain the Two Thousand Nine H One and One Flue?

Pigs have long been considered a possible mixing vessel for influenza viruses that originate within pigs, birds and humans. Reassortment between influenzi irises found in north american and eurasian pigs had already occurred at least once naturally in the five years prior to the identification of the two thousand nine h one nd one flue. As for the idea that flues come from the east, that's actually kind of been borne out by search, but it's not a universal thing. A study by the university of chicago noted that 87 % of the most successful globaly spreading strains of h three n two originated in east, south and southeast asia.
