OP don't be too quick to take this as gospel truth. First of all look at the names of who was involved in the study and who is conducting this "research"

All Chinese yet you automatically believe it same with poster #2 and #3. It MAY be true, we don't know if the info is BS

Do you hear news from China and then rush out and say that is the truth?

Secondly, there are various strains so it could be the strain they studied did not spread with a s people but the other strains especially the one they gave us may.

I hope the study is true but you gotta take some time, think and scratch your head a little before posting and rushing to conclusions.
ps I hope you are right
pss I ope you are right
But info straight form China. Things that make you go hmmmm
