Episode notes
Uncertain Origin
- Scientists traced COVID-19 to bats, but how it jumped to humans is unclear.
- The earliest COVID-19 cases lacked clear ties to the Wuhan market.
Lab Accident Theory
- The Trump administration suggests a lab accident released the virus, but lacks evidence.
- Scientists find this theory problematic, favoring zoonotic spillover.
Bat Coronaviruses
- Simon Anthony estimates bats carry 3,700 coronaviruses, but few infect humans.
- For a lab accident, a researcher would need to find a highly infectious one, which is unlikely.
