The clustering of early cases around the Huanan market reflects where the COVID-19 virus emerged, not just where testing looked

Like all known human coronaviruses, SARS-CoV-2 originated from animals, most likely through wildlife sold at the Huanan Seafood Market, with bats serving as the deeper evolutionary reservoir. Since its emergence in humans, SARS-CoV-2 has repeatedly c...

The Huanan seafood market in Wuhan, China, played a significant role in the early transmission and amplification of the virus, with 60% of early cases in December 2019 that could be traced to the market or [people who] lived in close proximity to the...

Here we show that Weissman's conclusion is based on a flawed premise, and that there is no such "internal evidence" of major bias. The pattern can indeed be explained by places of infection not being limited to residential neighbourhoods, and by stoc...

Our analyses indicate that the emergence of SARS-CoV-2 occurred via the live wildlife trade in China, and show that the Huanan market was the epicenter of the COVID-19 pandemic.

We also know that the Huanan Seafood Market in Wuhan had a significant role in the early transmission and initial spread of the virus. Metagenomic sequencing of environmental samples collected at the market has indicated that several wildlife species...

Pointing out that COVID leaked from a lab in Communist China was never a conspiracy, it was common sense. The conspiracy was Tony Fauci and his assistants doing Xi Jinping’s dirty work and lying about COVID’s origins. I’m thankful that the Department...

China has actively participated in global virus origins-tracing efforts with the greatest sincerity, as it firmly upholds that the truth does not lie in premature accusations but in meticulous data-based verification. Through systematic epidemiologic...

I showed that the latter theory at least gave the correct sign of the difference between the median distances from HSM to unlinked vs. to linked cases, while the Worobey model gave the wrong sign.

the odds of observing the spatiotemporal pattern of confirmed COVID-19 cases with no known link to the specific wholesale market where wildlife mammals were being sold […] These four conditional Bayes factors are estimated as 2.3:1, 20:1, 27:1, and 1...

The HSM early cluster is therefore negligible as evidence. Our analysis assigns it 2x.

A comparison of the distances to the Huanan Seafood Market of early Covid cases with known links to the market versus cases without known links shows results apparently incompatible with a location model lacking proximity ascertainment bias. The sign...

We show that this statistical conclusion is invalid on two grounds ... Hence, the question of the origin of the pandemic has not been answered by their statistical analysis.
