The coronavirus pandemic began in separate viral spillovers — at least two but perhaps as many as two dozen — from live animals sold and butchered in late 2019 at the Huanan Seafood Market in Wuhan, China, according to two papers published Tuesday in the journal Science.
The publication of the papers, which underwent five months of peer review and revisions by the authors, is unlikely to quell the rancorous debate about how the pandemic began and whether the virus emerged from a Chinese laboratory. And the authors acknowledge there are many unknowns requiring further investigation — most notably, which animals were involved.
“Everything upstream of this — which animals, where did they come from, how it’s all connected — is completely unknown at this stage,” Kristian Andersen, an immunologist at Scripps Research, said in a media briefing Tuesday.

“Have we disproven the lab leak theory? No, we have not. Will we ever be able to? No. But there are ‘possible’ scenarios and there are ‘plausible’ scenarios. … ‘Possible’ does not mean equally likely,” Andersen said.
A natural origin of the pandemic — a “zoonosis” — has long been a favored theory among scientists for the simple reason that most pandemics, including the SARS coronavirus outbreak of 2002-2003, have started that way. Andersen and his colleagues believe multiple lines of evidence, including the clustering of early cases of covid-19 around the market, make a market origin not only a likely scenario but the only one that fits the data.
