Misinformation about lab leak theory of SARS-CoV-2 origin

Summary

No evidence has been put forward that substantiates the claim that SARS-CoV-2 originated in a lab.

2 US government agencies (FBI & DOE) have determined with low or medium confidence that SARS-CoV-2 originated in a lab, but have not revealed their basis for these conclusions.

Significant evidence (including some published or revealed after the FBI/DOE conclusions were revealed) give compelling reason to believe that a natural origin is far more likely.

Agencies endorsing lab leak theory

FBI

The FBI concluded with "moderate confidence" in 2001 that a lab incident was the likely origin of SARS-CoV-2. The FBI has not revealed the basis for this conclusion.

Evidence for natural origin

"The Huanan Seafood Wholesale Market in Wuhan was the early epicenter of the COVID-19 pandemic"

An analysis of samples taken from the Huanan Seafood Wholesale Market in Wuhan show that large amounts of the virus were mixed in with genetic material from racoon dogs.

Prooving the origin of any virus is challenging

It took years to find the origin of HIV in chimpanzees.

It took years to trace the path of SARS-CoV(-1) from bat to civet cat to human.

The origin of Ebola is not known.
