A new study conducted in a Ugandan forest has established a link between deforestation and viral disease transmission. Animals living in that forest lost a source of food and were forced to eat virus-laden bat feces instead. Among the viruses found in the feces, known as “guano” is a relative of COVID-19. Host Carolyn Beeler speaks with Pawel Fedurek, lead researcher in the study, about how this research could shed light on how new viruses can spread from animals to humans.
