Waterborne protozoa (WBP) are important cause of several outbreaks all over the world. The report system of WBP in Africa is weak. More than one third of African countries (21/54) reported WBP with absent reports in the remaining countries (33/54). The top reported WBP were Cryptosporidium, Giardia, FLA and Entamoeba contaminating different African water resources. Other protozoa were less documented even though it is abundant and robust. More than one protozoa were detected in contaminated African water including drinking sources, a prediction index to popular epidemics and real presence of undocumented WBP outbreaks. Risk factors in Africa were observed to be abundant and multi-factorial 'socioeconomic, governmental, pathogen in water and climate change. Climate change is an important factor impacting Africa. Increasing droughts in Africa with other extreme weather events will lead to water crises. Incidence and transmission of WBP will change, with new manifested strains/species. Recognizing future consequences of water crises in Africa are important. Governments and population unity will be needed to protect against expected raise and spread of WBP diseases and water shortages.
水传播原生动物(WBP)是世界上几次暴发的重要原因。非洲的 WBP 报告系统薄弱。超过三分之一的非洲国家(54 个中的 21 个)报告了 WBP,其余国家(54 个中的 33 个)没有报告。报告的主要 WBP 有隐孢子虫、贾第虫、肠贾第虫和内阿米巴,污染了不同的非洲水资源。其他原生动物虽然丰富且强壮,但记录较少。受污染的非洲水中检测到一种以上的原生动物,包括饮用水源,这是流行疫情的预测指标和未记录的 WBP 暴发的真实存在。非洲的风险因素被观察到是丰富和多因素的,包括社会经济、政府、水中病原体和气候变化。气候变化是影响非洲的一个重要因素。非洲干旱加剧和其他极端天气事件将导致水资源危机。WBP 的发病率和传播将发生变化,出现新的表现型/物种。认识到非洲水资源危机的未来后果很重要。需要政府和民众团结起来,防止预期的 WBP 疾病和水资源短缺的增加和传播。
