作者对法国野生动物狂犬病的成本进行了评估。这项研究包括家畜疫苗接种、加强流行病学监测网络和向诊断实验室提供支持、与狂犬病暴发有关的费用（动物损失和相关的经济损失）、对咬人动物的临床观察以及预防性疫苗接种和人类接触后治疗。这笔费用的很大一部分（72%）用于家畜的预防性疫苗接种。在法国，与红狐（Vulpes Vulpes）是受影响最严重的物种的其他欧洲国家一样，评估了在水库一级控制该疾病的两种主要战略，即：狐狸种群减少和狐狸口服疫苗接种。对狂犬病和两种策略的综合成本和效益进行了比较，并包括扑杀狐狸的成本或口服疫苗接种的成本（毒饵、毒饵输送和确保疫苗接种效率的随访）。两种策略的累积年成本在第四年之前保持可比性，之后口服疫苗接种策略变得有益。这一预测是在1988年作出的，1993年重新调整，五年后经事后分析证实。口服疫苗接种的预期益处现已获得。狐狸种群的减少只导致了疾病发生的短暂平静，而口服疫苗已被证明能够消除狂犬病，即使在狐狸种群增加的情况下。
The author presents an evaluation of the cost of wildlife rabies in France. This study included the vaccination of domestic animals, the reinforcement of epidemiological surveillance networks and the support provided to diagnostic laboratories, the expenses associated with outbreaks of rabies (animal losses and associated economic losses), the clinical observation of those animals which had bitten humans and the preventive vaccination and post-exposure treatment of humans. A substantial percentage (72%) of this cost was the preventive vaccination of domestic animals. In France, as in other European countries in which the red fox (Vulpes vulpes) is the species most affected, two main strategies for controlling the disease at the reservoir level were evaluated, namely: fox depopulation and the oral vaccination of foxes. The combined costs and benefits of rabies and of both strategies were compared and included either the cost of fox culling or the cost of oral vaccination (baits, bait delivery and follow-up to ensure the efficiency of the vaccination).The cumulative annual costs of both strategies remained comparable until the fourth year, after which the oral vaccination strategy became beneficial. This forecast was made in 1988, readjusted in 1993 and confirmed by ex post analysis five years later. The expected benefits of oral vaccination have now been obtained. Fox depopulation has only ever resulted in a transient lull in the occurrence of the disease, while oral vaccination has proved to be capable of eliminating rabies even in situations in which fox populations were increasing.
