Some conclusions from the WHO mission to China, nothing new really
- Virus came from bats, most likely via transmission of an in between (still unknown) other animal.
- It didn't start at the Seafood market (already known there were earlier cases) and it seems to be just an early cluster although the market did also sell domesticated animals "some of these animals have been traced to farms or traders in regions that are home to bats that carry the virus that is the closest known relative of the one that causes COVID-19." It could also have been transferred via frozen seafood, but most likely just through an already infected person (Chinese health officials note that only surfaces at the market tested positive for the virus, not any of the animal products. there were cases elsewhere in Wuhan around the same time as the market cluster)
- The lab theory just doesn't hold any ground, very unlikely
- The joint investigation left open the possibility that the virus could have been spread to humans through frozen food products, a bit of a surprise as foreign experts have generally played down the risk...
Anyway, still unknown where or how it started.
