Words From the News 2

Two major scientific studies point to a market in Wuhan, China — not a lab in the same city — as the birthplace of the coronavirus pandemic. 

Researchers concluded that the coronavirus was present in live mammals sold in the Huanan Seafood Wholesale Market in Wuhan, China, in late 2019. The research suggests that the virus very likely twice spilled over into people working or shopping at the market. The researchers said they found no support for an alternate hypothesis that the coronavirus escaped from a lab in Wuhan.
