Wildlife Trade Linked to Rising Human Disease Risk, Major Study Finds
53 articles · Updated · The New York Times · Apr 14
A major new study finds that mammals involved in the global wildlife trade are significantly more likely to carry pathogens that can infect humans.
Researchers analysed 40 years of trade and disease data, revealing traded species are 1.5 times more likely to share infectious agents with humans.
Longer time in trade increases risk, with each decade adding an additional pathogen, highlighting wildlife trade as a growing driver of zoonotic disease emergence.
Does the wildlife trade create new diseases, or does it just help existing ones find us?
As traded animals get more dangerous over time, which species pose the next pandemic threat?
Why is demand for exotic animals still high despite the clear pandemic risks they pose?

The 2026 Science Study Reveals Wildlife Trade as a Major Driver of Zoonotic Pandemic Risk
Overview
A major 2026 study revealed that the global wildlife trade significantly increases the risk of zoonotic diseases, especially through high-risk settings like live animal markets and the exotic pet trade. Stressful capture, cramped transport, and mixing of diverse species amplify pathogen spread. The lack of global disease surveillance and weak enforcement of regulations allow dangerous pathogens to circulate undetected until they spill over to humans, as seen in the COVID-19 pandemic. Geographic hotspots like Southeast Asia and Central Africa face heightened risks due to biodiversity and human activity. Addressing these challenges requires integrated One Health surveillance, demand reduction, and strong global cooperation to prevent future pandemics.
