Peste des petits ruminants (PPR) is an important infectious viral disease of domestic small ruminants that threatens the food security and sustainable livelihood of farmers across Middle East, Africa, and Asia. The objective of this research is to analyze the disease's spread and its impacts on direct government costs through conducting three simulations of different control strategies to reduce and quickly eradicate PPR from the United Arab Emirates in the near future. A Modified Animal Disease Spread Model was developed in this study to suit the conditions of the United Arab Emirates. The initial scenario represents when mass vaccination is ceased, and moderate movement restrictions are applied. The second scenario is based on mass vaccination and stamping out the disease, whereas the third simulation scenario assumes mass and ring vaccination when needed, very strict movement control, and stamping out. This study found that the third scenario is the most effective in controlling and eradicating PPR from the UAE. The outbreak duration in days was reduced by 57% and the number of infected animals by 77% when compared to the other scenarios. These results are valuable to the country's animal health decision-makers and the government's efforts to report to the World Animal Health Organization (OIE) regarding the progress made towards declaration of the disease's eradication. They are also useful to other concerned entities in other Middle Eastern, North African, and Asian countries where the disease is spreading.
小反刍兽疫(PPR)是家养小反刍动物的一种重要病毒性传染病,威胁着中东、非洲和亚洲农民的粮食安全和可持续生计。本研究的目的是通过对三种不同控制策略进行模拟,分析该疾病的传播及其对政府直接成本的影响,以便在不久的将来减少并迅速根除阿联酋的小反刍兽疫。本研究开发了一种改良的动物疾病传播模型以适应阿联酋的情况。初始情景代表停止大规模疫苗接种并实施适度的移动限制时的情况。第二种情景基于大规模疫苗接种和扑杀疾病,而第三种模拟情景假设在需要时进行大规模和环状疫苗接种、非常严格的移动控制以及扑杀。本研究发现,第三种情景在控制和根除阿联酋的小反刍兽疫方面最为有效。与其他情景相比,疫情持续天数减少了57%,感染动物数量减少了77%。这些结果对于该国的动物卫生决策者以及政府向世界动物卫生组织(OIE)报告在宣布根除该疾病方面取得的进展的努力具有重要价值。它们对于该疾病正在传播的其他中东、北非和亚洲国家的其他相关实体也很有用。
