According to what I heard, Wuhan in China was on lockdown when the virus started. I think they were able to withhold the virus from spreading to their other states by immediately locking down Wuhan and preventing movements.And of course, I have read a lot of people say that the China created the virus.

A lot of things has been said about this and people who say it usually point out valid points on what made them make such statements. There were lots of journalists and doctors that went missing after they tried to let the world know about the virus. This makes it seem like they were trying to cover up about the virus and has silenced those scientists and journalists.
