In late June, the Scientific Advisory Group for the Origins of Novel Pathogens (SAGO) of the World Health Organization (WHO) issued a report concluding that the most likely origin of COVID-19 is zoonotic, suggesting it spilled over from animals to humans, specifically at the Huanan market in Wuhan. The report found no evidence to support the theory of a lab leak, which has been a focal point for various conspiracy theories that undermine trust in science and public health efforts.
Researchers, including authors of a significant 2020 study in Nature Medicine, have faced political attacks and conspiracy theories alleging they promoted a preferred hypothesis due to external pressure. These claims misrepresent evidence and the scientific process, as no support for laboratory manipulation has emerged.
Extensive evidence suggests the pandemic started from zoonotic spillover, including a clustering of early cases near the Huanan market and scientific findings indicating that the virus’s features align with natural evolution. Environmental samples have shown genetic material consistent with infected animals present at the market.
The spread of conspiracy theories has detrimental effects on public trust in science and can justify cuts to crucial funding for biomedical research and public health, ultimately undermining preparedness for future pandemics. By focusing on conspiratorial narratives instead of the well-supported zoonotic origin, we risk neglecting the real dangers posed by the wildlife trade and our ability to respond to emerging health threats.
