Malaria is a long-standing public health problem in sub-Saharan Africa, whereas arthropod-borne viruses (arboviruses) such as dengue and chikungunya cause an under-recognised burden of disease. Many human and environmental drivers affect the dynamics of vector-borne diseases. In this Personal View, we argue that the direct effects of warming temperatures are likely to promote greater environmental suitability for dengue and other arbovirus transmission by Aedes aegypti and reduce suitability for malaria transmission by Anopheles gambiae. Environmentally driven changes in disease dynamics will be complex and multifaceted, but given that current public efforts are targeted to malaria control, we highlight Ae aegypti and dengue, chikungunya, and other arboviruses as potential emerging public health threats in sub-Saharan Africa.
疟疾是撒哈拉以南非洲长期存在的公共卫生问题，而蚊媒病毒（虫媒病毒）如登革热和基孔肯雅热则造成了被低估的疾病负担。许多人类和环境驱动因素影响着虫媒传染病的动态。在这篇个人观点中，我们认为变暖的气温的直接影响可能会促进埃及伊蚊传播登革热和其他虫媒病毒的环境适宜性增加，并降低冈比亚按蚊传播疟疾的适宜性。疾病动态的环境驱动变化将是复杂和多方面的，但鉴于目前的公共努力针对的是疟疾控制，我们强调埃及伊蚊和登革热、基孔肯雅热以及其他虫媒病毒可能成为撒哈拉以南非洲新出现的公共卫生威胁。
