Unraveling the Zoonotic Origin and Transmission of SARS-CoV-2

Trends Ecol Evol. 2021 Mar;36(3):180-184. doi: 10.1016/j.tree.2020.12.002. Epub 2020 Dec 13.


The origin and zoonotic transmission route of SARS-CoV-2 remain speculative. We discuss scenarios for the zoonotic emergence of SARS-CoV-2, and also explore the missing evidence and ecological considerations that are necessary to confidently identify the origin and transmission route of SARS-CoV-2 and to prevent future pandemics of zoonotic viruses.
