      Team did a “detailed and profound search” for cases that might have been missed, says @Peterfoodsafety. “We did not find evidence of large outbreaks that could be related to cases of #COVID19 prior to December 19 in Wuhan or elsewhere."

      Picture becoming clearer of Huanan market being just part of the spread of #sarscov2 in Wuhan in December, says @Peterfoodsafety. “It was not just only a cluster outbreak in the Huanan market, but the virus was also circulating outside of the market."

      It "is a very classical picture of the start of an emerging outbreak, where we start with a few sporadic cases early on in the month of December and then we start to see small outbreaks where the disease starts to spread in clusters” incl. the Huanan market, says @Peterfoodsafety

      "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 @ClancyNeil @kakape and

      Could be internal, too, but is there any actual evidence of cold chain spread? I'm curious specifically because they do feel confident enough to rule out lab as not worthy of any further inquiry but not frozen food? If cold chain is suspect, we should act like it here.

          It's related to propaganda that the CCP is spreading internally, which allows them to both deflect the blame for the origin of the virus as well as outbreaks occuring inside of China.https://www.reuters.com/article/us-health-coronavirus-china-origin-idUSKBN2861A2 …

          They have no data to present for that though so it is a political decision. Just don’t present it as scientific.
