From what I can determine, the virus from bats infected the Pangolin which infected humans. It may well be that infected bats were caged above live Pangolins in the The Huanan Seafood Wholesale Market (the Wet Market) in Wuhan. Bat fecal droppings or saliva may have contaminated the food the Pangolins were eating in the market.
Nope. Bioengineered.
