The Trump administration has advanced the theory the coronavirus began as a lab accident, but scientists who research bat-borne coronaviruses disagree. Speaking with NPR, ten virologists and epidemiologists say the far more likely culprit is zoonotic spillover⁠—transmission of the virus between animals and humans in nature. We explain how zoonotic spillover works and why it's more plausible than a lab accident.To manage podcast ad preferences, review the links below:See pcm.adswizz.com for information about our collection and use of personal data for sponsorship and to manage your podcast sponsorship preferences.NPR Privacy Policy
