Recent research published in Science establishes a direct link between the global wildlife trade and the transmission of zoonotic pathogens from mammals to humans. By analyzing four decades of data, scientists discovered that traded mammal species are significantly more likely to share infectious diseases with humans than those not involved in commerce. A critical finding reveals that for every ten years a species remains in the international market, it typically gains one additional shared pathogen with the human population. The risk of disease exchange is further heightened when animals are traded live or through illegal channels, where sanitary oversight is absent. These results suggest that the duration and intensity of human-animal contact in trade networks are primary drivers of potential epidemics and pandemics. Consequently, the authors advocate for stricter biosurveillance and updated international regulations to mitigate the inherent health risks posed by the commercial use of wildlife.
