The preprint describing a SARS-CoV-2 variant (VUI) unreliably detected in nasopharyngeal samples is out medrxiv.org/content/10.110… short 🧵, *not peer-reviewed* 1/7 In January 2021, Dr Dufour at the Lannion hospital (West of France) was puzzled by a cluster of respiratory infections with classic COVID-19 clinical presentation, but for which qPCRs on (repeated) nasopharyngeal samples were negative. 2/7

Very excited to share our new #PrePrint where we report a virus closely related to SARS-CoV-2 found in bats from Cambodia! @PasteurCambodia @institutpasteur biorxiv.org/cgi/content/sh… short 🧵1/7 The virology team @PasteurCambodia has screened 400+ archived samples of wild animals incl. different bat species, and found a positive SARS-like signal in rectal swabs of 2 Rhinolophus shameli bats from 2010. 2/7

We’ve prepared a short report on the early introductions and spread of #SARS-CoV-2 in the northern regions of France doi.org/10.1101/2020.0…. Find some key messages below. #COVID19 (1/9) Several early introductions to France do not appear to have led to further spread likely due to effective contact tracing and isolation. (2/9)
