Lake Victoria is the primary source of water for millions of people in the Sub-Saharan Africa region. In recent years, population development around the lake has resulted in compromised sanitation standards resulting in increased faecal pollution of the lake. Consequently, this condition has increased the chances of waterborne enteric viruses, such as adenoviruses’ circulation in the community. Adenoviruses can affect health in both humans and animals by causing a myriad of diseases including the gastrointestinal infections. The study aimed to detect contamination of the lake water with pathogenic human adenoviruses along Homa Bay town, Homa Bay County, Kenya. To examine the presence of adenoviral genome, we collected a total of 216 (monthly n = 36) water samples from six different locations marked by high levels of anthropogenic activities along the shoreline. Molecular amplification technique using the nested PCR procedure was used to detect the genomes from the water samples. Human adenoviruses were detected in 11 samples (5.09%). Statistical analyses indicated a significant correlation between adenovirus presence and the approximate distance from pit latrines and sewage treatment works at the area. The findings indicate that faecal contamination of the lake waters originated from the point sources. The findings also suggest a possibility of elevated levels of faecal pollution in different surface waters within the lake basin. The findings indicate that some of the enteric viruses circulating in the local community are human adenovirus type 40, and 41. The data may provide a basis for recognizing the need to prioritize environmental monitoring for enteric virus contamination on an on-going basis.

维多利亚湖是撒哈拉以南非洲地区数百万人的主要水源。近年来，湖泊周围的人口发展导致卫生标准下降，导致湖泊的粪便污染增加。因此，这种情况增加了水源性肠道病毒（例如腺病毒）在社区中传播的机会。腺病毒可引起包括胃肠道感染在内的多种疾病，从而影响人类和动物的健康。该研究旨在检测肯尼亚霍马湾县霍马湾镇湖水是否受到致病性人类腺病毒的污染。为了检查腺病毒基因组的存在，我们总共收集了 216 个（每月n = 36) 来自六个不同地点的水样，以沿海岸线的高水平人为活动为标志。使用嵌套式 PCR 程序的分子扩增技术用于检测水样中的基因组。在 11 个样本 (5.09%) 中检测到人类腺病毒。统计分析表明，腺病毒的存在与该地区距坑式厕所和污水处理厂的大致距离之间存在显着相关性。研究结果表明，湖水的粪便污染源于点源。研究结果还表明，湖盆内不同地表水中的粪便污染水平可能会升高。研究结果表明，在当地社区传播的一些肠道病毒是人类腺病毒 40 型和 41 型。
