Chinese scientists publish long-awaited data on Covid origins

A research team in China has published analysis of samples taken more than three years ago from the market linked to the outbreak of Covid-19.

The Huanan seafood and wildlife market has been a focal point in the search for the origin of the coronavirus.

But this is the first peer-reviewed study of biological evidence gathered from the market back in 2020.

By linking the virus with animals sold in the market, it could open new lines of inquiry into how the outbreak began.

The research reveals swabs that tested positive for the virus also contained genetic material from wild animals.

Some scientists say this is further evidence that the disease was initially transmitted from an infected animal to a human.

 

But others have urged caution in interpreting the findings and it remains unclear why it took three years for the genetic content of the samples to be made public.

Yes, we should always believe without question what the Chinese authorities tell us ....

"preliminary investigations" dated 2019 before most of the rest of the world had even heard of covid.

 

Now there' research pointing to racoon dogs, whatever they are.

 

Particularly notable was the raccoon-dog mitochondrial DNA found in six samples from two stalls. These small fox-like animals are susceptible to SARS-CoV-2, and can spread the infection to other raccoon dogs without showing clear signs of sickness2. Raccoon dogs and masked palm civets have also been found with infections of viruses that are almost identical to the one that causes severe acute respiratory syndrome, which is related to SARS-CoV-2 and caused an outbreak in people in 2003.
