Viral zoonoses pose a significant public health challenge in Africa, characterized by a diverse array of pathogens transmitted from animals to humans. This review maps the geographic distribution of zoonotic viral diseases in Africa, including rodent-borne, bat-borne, tick-borne, mosquito-borne, and sandfly-associated viral zoonoses, along with those transmitted via fecal-oral and respiratory routes. This review informs surveillance, resource allocation, and One Health strategies by mapping zoonotic viral disease risks across Africa based on geographic existence. The overlapping clinical symptoms of these infections, particularly fever and headache, with endemic parasitic diseases, such as malaria and/or other intestinal parasitic infections, complicate accurate diagnosis, timely treatment, and case management, and further contributing to increased morbidity and mortality. The limited diagnostic capabilities and resource constraints of healthcare systems hinder effective surveillance and outbreak response, exacerbating the risks associated with zoonotic diseases. The economic burden of viral infections poses significant challenges for communities reliant on livestock. Therefore, identifying and mapping zoonotic viral diseases is critical to informing integrated strategies that address human, animal, and environmental health. A One Health approach, which recognizes the interconnectedness of these domains, is essential for managing the complex dynamics of zoonotic diseases transmission. strengthening surveillance systems, improving public health education, and strategically allocating resources are key to reducing the impact of viral zoonoses across Africa. Collaborative engagement among governments, non-governmental organizations, and international health agencies is crucial for building resilient health systems capable of responding effectively to both existing and emerging zoonotic threats.
病毒性人畜共患病在非洲构成了重大的公共卫生挑战,其特点是有各种各样的病原体从动物传播给人类。本综述绘制了非洲人畜共患病毒性疾病的地理分布图,包括啮齿动物传播、蝙蝠传播、蜱传播、蚊子传播以及与白蛉相关的病毒性人畜共患病,还有通过粪口途径和呼吸道传播的疾病。本综述通过根据地理分布绘制非洲各地人畜共患病毒性疾病风险图,为监测、资源分配和“同一健康”战略提供信息。这些感染的临床症状与疟疾和/或其他肠道寄生虫感染等地方性寄生虫病的症状重叠,尤其是发热和头痛,这使得准确诊断、及时治疗和病例管理变得复杂,并进一步导致发病率和死亡率上升。医疗系统有限的诊断能力和资源限制阻碍了有效的监测和疫情应对,加剧了与人畜共患病相关的风险。病毒感染带来的经济负担给依赖牲畜的社区带来了重大挑战。因此,识别和绘制人畜共患病毒性疾病对于制定解决人类、动物和环境健康问题的综合战略至关重要。“同一健康”方法认识到这些领域的相互关联性,对于管理人畜共患病传播的复杂动态至关重要。加强监测系统、改善公共卫生教育和战略资源分配是降低非洲各地病毒性人畜共患病影响的关键。政府、非政府组织和国际卫生机构之间的合作参与对于建立能够有效应对现有和新出现的人畜共患威胁的有弹性的卫生系统至关重要。
