非洲所有地区都报告了登革热的爆发和流行，据信所有四种登革热病毒血清型都在传播。现有数据表明，登革热是34个非洲国家的地方病，已知除5个国家外，所有国家都有埃及伊蚊-登革热传播的主要媒介。根据现有数据，很难确定非洲人口是否与亚洲和拉丁美洲人口一样容易感染登革热。有几个因素可能影响登革热在非洲的传播，包括媒介效率、病毒感染性、宿主脆弱性和环境因素，如城市化程度的提高。非洲目前的登革热预防战略侧重于病媒控制，尽管这种努力的主要目的通常是预防疟疾。需要进一步研究，以确定非洲登革热的流行病学，并更好地了解非洲各地登革热易感性差异所涉及的因素。
Dengue outbreaks and epidemics have been reported in all regions of Africa, and it is believed that all four dengue virus serotypes are in circulation. Available data suggest that dengue is endemic to 34 African countries and that Aedes aegypti mosquitoes – the primary vector for dengue transmission – are known to be present in all but five countries. Whether populations in Africa are susceptible to dengue at the same rates as in Asia and Latin America is difficult to determine from the available data. Several factors may affect the transmission of dengue in Africa, including vector efficiency, viral infectivity, host vulnerability and environmental factors, such as increasing urbanisation. Current dengue prevention strategies in Africa focus on vector control, although the primary aim of such efforts is typically the prevention of malaria. Further research is needed to characterise the epidemiology of dengue in Africa and to better understand the factors involved in differences in vulnerability to dengue across Africa.
