Scientists searching for the origins of COVID-19 have zeroed in on a short list of animals that possibly helped spread it to people. Researchers analyzed genetic material gathered from the

With genetic samples from the infamous Wuhan market, a new study makes the case that raccoon dogs are likely the animal that infected humans. Proponents of the lab leak theory are dubious.

Genetic tracing at the Huanan Seafood Market supports hypothesis that the COVID pandemic spread from animals there.

After an in-depth analysis of the genetic material from hundreds of swabs taken from the walls, floors, machines and drains inside the Huanan Seafood Wholesale Market in Wuhan, China — a site that’s been described as an epicenter of early spread of Covid-19 — scientists say they now know exactly which species of animals were in the same area where investigators also found the most positive samples the virus that causes Covid-19.

A University of Arizona researcher was part of a study strongly linking pandemic origin to the seafood market in China.

That theory is now supported by a new study analyzing more than 800 samples collected in and around the market in January 2020 as the pandemic began. Those samples show that animal species known to carry the COVID coronavirus were present in the market,

The hunt for the origin of the COVID-19 pandemic has new leads. Researchers have identified half a dozen animal species that could have passed SARS-CoV-2, the coronavirus that causes COVID-19, to people,

A new peer-reviewed paper presents evidence that the COVID-19 pandemic started in a seafood market in Wuhan, China, where many of the first cases of the disease were identified. The paper, published Thursday in the scientific journal Cell,
