COVID in waste, with Dave O’Connor and Marc Johnson

In this episode Jason speaks to virologists Dave O’Connor and Marc Johnson from the University of Wisconsin–Madison.


For the past year they have been hunting down a heavily mutated strain of SARS-CoV-2, the virus that causes COVID-19 in a search that has led them to scour through everything from sewage water to dog poo.


In this episode they explain how viruses mutate, how there may be rogue forms of coronavirus still out there and how we can track viruses down.
