Illicit animal trade and infectious diseases
研究发现，活体动物贸易中的瞒报行为（如物种误分类和低价申报）会传播动物传染病，贸易额每增加1%，感染病例上升0.3%至0.5%，而严格的边境检查能有效降低这一风险。
Can evasionary practices in the commercial trade of live animals spread infectious animal diseases? We analyze the link between discrepancies in the traded value of live animals that are reported by partner countries – a proxy measure which has been used in the trade literature to uncover evidence on smuggling across items like antiques, cultural property, or natural resources – and infectious animal diseases. The results imply that a 1% increase in illicit live animal trade is associated with a 0.3% to 0.5% rise in infection cases in animals, which is driven by evasionary practices like species mis-classification and under-pricing. Crucially, we demonstrate that robust border inspections effectively curb these risks, offering a practical tool to combat the spread of animal diseases through illicit live animal trade. • Evasionary practices in live animals trade spread infectious animal diseases. • Mis-classification and under-pricing drive the impact of illicit trade on infections. • Border inspections moderate the effect of illicit trade on animal diseases.
