African swine fever (ASF) is a highly fatal disease of pigs. It is a threat to the pig industry as it lowers production and significantly impacts on livelihoods. ASF has no cure and a vaccine against it is yet to be developed. Outbreaks continue to be reported in Africa and Asia, where the setting of the pig value chain (farm, market, and slaughter practices) coupled with the risky behaviors of actors, contribute to persistence of the virus in pig populations. The role of these factors in the epidemiology of the disease is reviewed with a focus on smallholder pig systems in Africa. Biosecurity at the farm level is particularly emphasized, and factors influencing its adoption highlighted. Socio-cultural factors and weaknesses at the disease control policy level are critical and should not be ignored. Gender and equity are important aspects and ought to be considered in discussions to improve the sector. The findings are expected to define priorities for interventions to improve pig productivity (as these regions wait for the vaccine to be developed).
非洲猪瘟（ASF）是一种猪的高致命性疾病。它对养猪业构成威胁，因为它会降低产量并严重影响生计。非洲猪瘟无法治愈，针对它的疫苗尚未研发出来。非洲和亚洲持续有疫情报告，在这些地区，猪价值链（农场、市场和屠宰环节）的情况以及从业者的危险行为，导致病毒在猪群中持续存在。本文回顾了这些因素在该疾病流行病学中的作用，重点关注非洲的小农养猪系统。特别强调了农场层面的生物安全，并突出了影响其采用的因素。疾病控制政策层面的社会文化因素和薄弱环节至关重要，不应被忽视。性别和平等是重要方面，在旨在改善该行业的讨论中应予以考虑。预计这些研究结果将确定提高生猪生产力的干预重点（因为这些地区在等待疫苗研发出来）。
