Abstract

Foot-and-mouth disease (FMD) is a contagious viral disease that affects the livelihoods and productivity of livestock farmers in endemic regions. It can infect various domestic and wild animals with cloven hooves and is caused by a virus belonging to the genus Aphthovirus and family Picornaviridae, which has seven different serotypes: A, O, C, SAT1, SAT2, SAT3, and Asia-1. This paper aims to provide a comprehensive overview of the molecular epidemiology, economic impact, diagnosis, and control measures of FMD in Ethiopia in comparison with the global situation. The genetic and antigenic diversity of FMD viruses requires a thorough understanding for developing and applying effective control strategies in endemic areas. FMD has direct and indirect economic consequences on animal production. In Ethiopia, FMD outbreaks have led to millions of USD losses due to the restriction or rejection of livestock products in the international market. Therefore, in endemic areas, disease control depends on vaccinations to prevent animals from developing clinical disease. However, in Ethiopia, due to the presence of diverse antigenic serotypes of FMD viruses, regular and extensive molecular investigation of new field isolates is necessary to perform vaccine-matching studies to evaluate the protective potential of the vaccine strain in the country.

摘要

口蹄疫(FMD)是一种传染性病毒病,影响流行地区牲畜养殖户的生计和生产力。它可以感染各种有蹄类的家畜和野生动物,由属于口疮病毒属和小 RNA 病毒科的病毒引起,有七种不同的血清型:A、O、C、SAT1、SAT2、SAT3 和 Asia-1。本文旨在全面概述埃塞俄比亚口蹄疫的分子流行病学、经济影响、诊断和控制措施,并与全球情况进行比较。口蹄疫病毒的遗传和抗原多样性需要深入了解,以制定和应用流行地区的有效控制策略。口蹄疫对动物生产有直接和间接的经济影响。在埃塞俄比亚,由于国际市场限制或拒绝牲畜产品,口蹄疫疫情导致了数百万美元的损失。因此,在流行地区,疾病控制依赖于接种疫苗来预防动物发生临床疾病。然而,在埃塞俄比亚,由于存在多种抗原血清型的口蹄疫病毒,需要定期和广泛地对新的田间分离株进行分子调查,以开展疫苗匹配研究,评估该国疫苗株的保护潜力。
