New data links Covid-19’s origins to raccoon dogs at Wuhan market
Analysis of gene sequences by international team finds Covid-positive samples rich in raccoon dog DNA
Newly released genetic data gathered from a live food market in Wuhan has linked Covid-19 with raccoon dogs, adding weight to the theory that infected animals sold at the site started the coronavirus pandemic, researchers involved in the work say.
Swabs collected from stalls at the Huanan seafood market in the two months after it was shut down on 1 January 2020 were previously found to contain both Covid and human DNA.
