One of the authors has posted a twitter thread explaining their findings.
If that’s still too long to read, then here is my very brief summation.
- Even cases with no known link to the Huanan Market are still geographically centered around the Huanan Market.
- The Huanan Market is the geographic epicenter of early cases.
- Genetic data suggests lineage B jumped in late November and started to spread, and A jumped a week or two after B.
- Positive environmental samples of SARS-CoV-2 were found in the Huanan Market on animal centered surfaces, such as cages.
- Cases in the market were nearer to stalls selling live mammals.
Here is a picture.
