布鲁氏菌病是一种人畜共患病，在巴西造成重大经济损失，因此该国制定了控制和根除这种疾病的国家方案。利用最近一次全国布鲁氏菌病调查中产生的数据，我们在巴西两个布鲁氏菌病状况不同的州--马托格罗索州(高发病率)和圣保罗州(低发病率)进行了经济分析。经济分析是基于通过接种3至8个月龄的小母牛接种S19疫苗来控制牛布鲁氏菌病的额外收益和成本的计算，考虑到该疾病的最大和最小影响。分析表明，与70%和80%的接种率相比，为3-8月龄的替代小母牛接种90%的疫苗在牛布鲁氏菌病疫苗接种计划中具有最好的经济效益。此外，牛布鲁氏菌病发病率较高的地区在实施疫苗接种战略以控制疾病时将获得显著的经济优势。这种经济分析将使决策者能够规划更经济有效的疫苗接种计划。(C)2014爱思唯尔B.V.保留所有权利。
Brucellosis is a zoonotic disease that causes important economic losses in Brazil, and the country has therefore established a national program for its control and eradication. Using data generated in the last national brucellosis survey, we conducted an economic analysis in two Brazilian States with different brucellosis status, Mato Grosso (with high prevalence) and Sao Paulo (with low prevalence). The economic analysis was based on the calculation of the additional benefits and costs of controlling bovine brucellosis through the vaccination of heifers aged between 3 and 8 months with S19 vaccine, considering maximal and minimal impacts of the disease. The analysis showed that vaccinating 90% of the replacement heifers aged 3-8 months of age offers the best economic performance in a vaccination program against bovine brucellosis if compared to vaccination rates of 70% and 80%. Moreover, regions with higher prevalences of bovine brucellosis would experience significant economic advantages when implementing a vaccination strategy to control the disease. This economic analysis will allow decision makers to plan more economically effective vaccination programs. (C) 2014 Elsevier B.V. All rights reserved.
