摘要

The global wildlife trade, encompassing both legal and illegal activities, and plays a crucial role in the emergence, transmission of zoonotic diseases, posing severe risks to biodiversity, public health, and global economies. The trade involves millions of live animals and their derivatives, spanning local markets to international networks, often operating with minimal regulation. Wildlife markets, especially those selling live animal as well as operating wet markets, bring different species into close contact, creating favorable conditions for pathogen to transmit from animals to humans. This has been associated with major zoonotic disease outbreaks, such as SARS, MERS, and COVID-19. The Illegal Wildlife Trade (IWT), classified as an environmental crime, exacerbates these risks by bypassing health and safety regulations, further increasing the chances of disease transmission. The overexploitation of wildlife, driven by high economic demand for exotic pets, traditional medicine, bushmeat consumption, and luxury goods, has led to biodiversity loss and habitat destruction, which in turn heightens human-wildlife interactions. Deforestation, land-use changes, and urbanization are example of anthropogenic pressures that upset ecosystems and bring wildlife closer to the human populations and domestic animals, which rises the risk of zoonotic spillover. Scientific research has shown that zoonotic pathogens, particularly RNA viruses, can mutate and adapt rapidly, making them highly capable of jumping between species. The emergence of novel pathogens, including coronaviruses and hemorrhagic fever viruses, underscores the need for an evidence-based approach to managing wildlife trade.
