A top chinese lab has confirmed today what some scientist suspected is the culprit for the new strain of avian influenza, H7N9.
The lab has been able to identify the genetic material associated with the cases, and has noted that it derives from a reassortment of wild birds from East Asia and chicken from East China, thereby validating the migratory route source that was initially suspected. The birds are suspected to have originated in a migratory pattern from the republic of Korea and other east Asian regions, who then mixed with ducks and chickens in the Yantze river during the migration season.
The new strain has been found to be completely alien to the strain of influenza found in pigs, thereby quelling the suspicions and accusations that Chinese authorities were hiding information about the epidemic which some believed originated with the dead pig carcasses found in a river near Shanghai.
