The global trade in wildlife provides disease transmission mechanisms that not only cause human disease outbreaks but also threaten livestock, international trade, rural livelihoods, native wildlife populations, and the health of ecosystems. Outbreaks resulting from wildlife trade have caused hundreds of billions of dollars of economic damage globally. Rather than attempting to eradicate pathogens or the wild species that may harbor them, a practical approach would include decreasing the contact rate among species, including humans, at the interface created by the wildlife trade. Since wildlife marketing functions as a system of scale-free networks with major hubs, these points provide control opportunities to maximize the effects of regulatory efforts.
全球野生动物贸易提供了疾病传播机制，不仅导致人类疾病爆发，还威胁到牲畜、国际贸易、农村生计、本地野生动物种群以及生态系统的健康。野生动物贸易引发的疫情已在全球造成数千亿美元的经济损失。与其试图根除病原体或可能携带病原体的野生物种，一种切实可行的方法应包括降低在野生动物贸易所形成的界面上物种（包括人类）之间的接触率。由于野生动物交易如同一个具有主要枢纽的无标度网络系统，这些关键点提供了控制机会，可使监管努力的效果最大化。
