Researchers studying bats in Northern Laos have found evidence that brings us closer than ever to understanding the origin of Covid-19. Since the beginning of the coronavirus pandemic scientists have tried to pin-point the exact origin of SARS-CoV-2. But recent evidence from the Institut Pasteur has identified several novel coronaviruses with similarities to the current coronavirus in bats. Professor Marc Eliot spoke to Roland Pease about how this research could give us a better idea where Covid-19 came from.
