Genetic Tracing Links SARS-CoV-2 With Animals at Wildlife Market

appears to have first leapt to humans from captive wildlife at the Huanan seafood market in Wuhan, and now a new study identifies specific animals thatThe new analysis – of metagenomic RNA data collected shortly after the market was shut down – also supports accumulating evidence forwere in Wuhan, the capital of China's Hubei province, in late 2019.

After initially swabbing surfaces in stalls where animals were held, the team returned days later to swab more stalls, cages, and carts, and to collect samples from drains and sewers. That enabled the new analysis, which identifies animal species in the samples by genotyping their mitochondrial genomes, the authors explain.

"Many of the key animal species had been cleared out before the Chinese CDC teams arrived, so we can't have direct proof that the animals were infected," Débarre

Genetic tracing at the Huanan Seafood market further supports COVID animal originsA new international collaborative study provides a list of the wildlife species present at the market from which SARS-CoV-2, the virus responsible for the COVID-19 pandemic, most likely arose in late 2019. The study is based on a new analysis of metatranscriptomic data released by the Chinese Center for Disease Control and Prevention (CDC).
