What is a virus? What does spillover mean? How can viruses infect humans? If these are things that you would like to know but lack the time or energy to research them, then welcome to The Viral Talk, the show which gives brief, direct and easy-to-understand answers to the big questions in virology. I am your host Federico De Angelis, a PhD student studying SARS-CoV-2 and other coronaviruses at the Roslin Institute, University of Edinburgh. Join me every other week to discover all the aspects of these obscure but fascinating organisms. Join in and Let's Go Viral.
