在南苏丹的一个地区进行了口蹄疫疫苗接种的效益-成本分析，该地区由于长期冲突，多年来一直受到大规模人道主义援助。该研究采用参与式流行病学(PE)方法，评估了不同年龄组牛的急性和慢性口蹄疫的患病率和死亡率，以及受口蹄疫影响的牛的产奶量的减少。接种口蹄疫疫苗的效益-成本为11.5。口蹄疫慢性病造成的损失占口蹄疫总损失的28.2%，这表明今后对非洲牧区和农牧区口蹄疫控制的效益-成本分析需要考虑慢性病造成的损失。还使用参与性流行病学方法评估牛奶在努尔族农牧民饮食中的重要性，以及与牛只迁徙和口蹄疫暴发有关的饮食季节变化。饮食上显著的季节性变化包括“饥饿间隙”时期，在此期间，家庭高度依赖牛奶作为主要食物来源。口蹄疫暴发恰好发生在这段依赖牛奶的时期之前，长期损失持续到这段时期，并影响到人类的粮食安全。本文探讨了南苏丹口蹄疫大规模接种和战略接种的必要性和可行性。该文件还讨论了将传统的效益-成本分析与生计分析相结合的价值，以便为人道主义背景下的疾病控制工作和资金承诺提供信息。
A benefit-cost analysis of vaccination for foot-and-mouth disease (FMD) was conducted in an area of South Sudan, which due to chronic conflict, had been subject to large-scale humanitarian assistance for many years. The study used participatory epidemiology (PE) methods to estimate the prevalence and mortality of acute and chronic FMD in different age groups of cattle, and the reduction in milk off-take in cows affected by FMD. The benefit-cost of FMD vaccination was 11.5. Losses due to the chronic form of FMD accounted for 28.2% of total FMD losses, indicating that future benefit-cost analyses for FMD control in pastoral and agropastoral areas of Africa need to consider losses caused by chronic disease. Participatory epidemiological methods were also used to assess the importance of milk in the diet of Nuer agropastoralists, and seasonal variations in diet in relation to cattle movements and FMD outbreaks. Marked seasonal variation in diet included a 'hunger gap' period during which households were highly dependent on milk as their main source of food. Outbreaks of FMD occurred immediately before this period of milk dependency, with chronic losses extending through this period and affecting human food security. The paper discusses the need and feasibility of mass vaccination and strategic vaccination for FMD in South Sudan. The paper also discusses the value of combining conventional benefit-cost analysis with livelihoods analysis to inform disease control efforts and funding commitments in humanitarian contexts.
