Covid-19 origins mirror SARS's genesis in animals, study finds

It gives a detailed explanation for SARS-CoV-2's genetic signatures, early epidemiology and research undertaken at the Wuhan Institute of Virology.

Early Covid-19 cases traced to markets in Wuhan, China, mirror the initial spread of SARS 17 years earlier, scientists said in a paper that concludes that an animal contagion is the most likely explanation for the pandemic’s genesis.

The epidemiological history of the SARS-CoV-2 virus is comparable to previous animal market-associated outbreaks of coronaviruses and offers a simple route for human exposure, Edward Holmes, Andrew Rambaut and 19 other researchers said in a review of the scientific evidence pertaining to the pandemic’s origins.

The paper was released Wednesday ahead of peer review, and is being prepared for submission to a
