Pair of new studies point to natural Covid origin

An animal market in China's Wuhan really was the epicenter of the Covid pandemic, according to a pair of new studies in the journal Science published Tuesday that claimed to have tipped the balance in the debate about the virus' origins.

Answering the question of whether the disease spilled over naturally from animals to humans, or was the result of a lab accident, is viewed as vital to averting the next pandemic and saving millions of lives.

The first paper analyzed the geographic pattern of Covid cases in the outbreak's first month, December 2019, showing the first cases were tightly clustered around Wuhan's Huanan Seafood Wholesale Market.
