H5N1 samples from Qinghai match those from 2004 outbreak in China

Quote from here:
"Samples recently recovered from China's western Qinghai Province show the virus there has been matched genetically to that found on the southeast coast, researchers say, reigniting a debate over whether it is being spread by migratory birds or human activities."

This information is consistent with my earlier hypothesis (explained here). I'm in the "human activity" is to blame camp.  It seems clear that H5N1 has been in Chinese domestic poultry and/or waterfowl since last June, undetected or unreported.
