Fact check
Is it true: COVID-19 Lab Leak Hypothesis?
It's still under investigation.
The origin of SARS-CoV-2 remains genuinely unresolved. The scientific community was initially divided between natural spillover (consistent with prior coronaviruses) and research-related origin (supported by WIV's coronavirus work, proximity to outbreak, and early biosecurity concerns). US intelligence agencies are split. A 2023 DOE assessment (low confidence) and FBI assessment (moderate confidence) favor lab origin; other agencies favor zoonosis. The "conspiracy theory" framing of early 2020 proved premature — serious scientists and officials now treat this as an open question.
The claim
The hypothesis that SARS-CoV-2 originated from a research-related incident at the Wuhan Institute of Virology (WIV) rather than from a natural zoonotic spillover at the Huanan seafood market.
Key evidence
WIV housed the world's largest coronavirus collection
Huanan market cluster: strong early zoonotic signal
