The Ralph Slatyer Medal Award ceremony and seminar

Professor Holmes will outline our current understanding of the key events in the origin and emergence of COVID-19 (SARS-CoV-2) at the end of 2019. Major topics of discussion will be possible zoonotic reservoirs for SARS-CoV-2, the diversity of SARS-CoV-2-like viruses in bats and other mammals, the signatures of origin written into genome sequences, and the possible role played by the Huanan market in Wuhan in the initial animal-to-human cross-species transmission event. Professor Holmes will show that there is increasing evidence that the emergence of SARS-CoV-2 strongly resembles of that of SARS-CoV some 17 years earlier. I will also address whether it is possible that SARS-CoV-2 emerged as a result of 'lab leak' from the Wuhan Institute of Virology and show that there is currently no scientifically robust evidence in support of that theory. Professor Holmes will also briefly consider possible scenarios for the future evolution of SARS-CoV-2 and conclude by considering the steps that can be taken to stop such a catastrophic pandemic event ever happening again
