Listening in on this and will tweet below #COVID19 https://twitter.com/drvyom/status/1359055005509058560

(Lengthy background info at the moment on process, terms of reference, etc)

Key findings coming up now. Starting with molecular epidemiology #COVID19

Reservoir hosts remain to be identified, investigators say. (Pangolins the world over sigh in relief) #COVID19

Evidence from surveys and targeted studies show bats and pangolins may be the reservoir, on the basis of high similarity between coronaviruses and #COVID19, but no convincing evidence of direct progenitor at present

High susceptibility of mink and cats to SARS-CoV-2 suggest feline family and other species could act as potential reservoirs. These are massively/inadequately undersampled at present #COVID19

Final analysis shows several cases with exposure to Huanan wet market had identical viral sequences, suggesting these were part of a cluster #COVID19

However sequence data also shows some viral diversity already present suggesting unsampled chains of transmission beyond the Huanan market #COVID19

Data suggests infections preceded earliest reported #COVID19 cases by several weeks, and the virus was already circulating in regions other than Wuhan, investigators say

Now hearing findings on source tracing #COVID19

No substantial unrecognised circulation in Wuhan in the latter part of 2019, they add, having looked at ILI surveillance. Retrospective testing 4,500 convenience samples dating back second half of 2019 in several regions also did not find evidence
