Coronavirus, coming to a neighborhood near you! In this episode we interview Xueting Qiu, a molecular epidemiologist at the Harvard T.H. Chan School of Public Health. After a brief recap of your fave viruses, including MERS (camels!), bird flu (poultry!) and COVID19 (bats? pangolins?), we chat about how next-generation sequencing and viral genetics are rapidly shaping our understanding of how COVID19 entered into humans, how it is spreading, and how its genome could affect therapeutics and vaccines.
