      "All the work that has been done on the virus, and trying to identify its origin continue to point towards a natural reservoir of this virus and similar viruses in bat populations”, says @Peterfoodsafety. “But … a direct jump from bats in the city of Wuhan is not very likely."

      Team evaluated four hypotheses, says @Peterfoodsafety. “We sat down and went through these different hypotheses, one by one, and assessed the likelihood by putting forwards arguments for and arguments against such hypotheses. And then assessing the likelihood of each of them."

      The 4 hypotheses: 1. direct zoonotic spillover 2. spillover from an intermediary host species that might have allowed virus to adapt more 3. introduction via food chain, for example from frozen products 4. lab-related incident

      "Our initial findings suggest that the introduction through an intermediary host species is the most likely pathway”, says @Peterfoodsafety. But direct spillover and food chain also need some more investigation.

      “However, the findings suggest that the laboratory incident hypothesis is extremely unlikely to explain introduction of the virus into the human population”, says @Peterfoodsafety suggests the team will not further follow-up that hypothesis with more studies.

      Replying to @kakape @WHO @Peterfoodsafety

      Do I understand this correctly? (Emphasis: I have no comment/assertion on lab accident hypothesis.) The team is asserting that they can *rule out* lab screw-up but *not* frozen food? That it's plausible that SARS-CoV-2 was introduced into China through frozen food from elsewhere?

      Replying to @zeynep @kakape and

      No and no. If I got it right: -they deem the lab incident very unlikely because SARS-cov-2 is not similar enough with virii studied in the lab; -Frozen food may be responsible for the *spread* of the virus across China, up to a food market.

      Replying to @edw_tweet @zeynep and

      The takeaway is that the virus may not have been generated by live animals at the wet market of Wuhan, but in a farm far away (but close from bat populations) whose food was then brought to the market.

      Sequence data "also showed that some diversity of viruses was already present in the early phase of the pandemic in Wuhan, suggesting unsampled chains of transmission beyond the Huanan market cluster”, says Wannian.

      So what are the odds that I don't see Kai's other tweets in the thread that I need them pointed out to me in response to a question?

          Sorry, I was just pointing at them again to stress/lean on them. Twitter is bad at referencing (especially multiple links form the same source: only one has a preview).

          The WHO team is not thinking it was "introduced into China through frozen food from elsewhere [than China]", but that it spread from another place *within China* (close to natural bat habitats) to the market (and other markets) through frozen food.
