摘要

Background Intestinal schistosomiasis continues to be a significant cause of morbidity among communities located around Lake Victoria and on its islands. Although epidemiological surveys have been conducted in other areas bordering the lake in western Kenya, Mbita district and its adjacent islands have never been surveyed, largely due to logistical challenges in accessing these areas. Consequently, there is a paucity of data on prevalence of schistosomiasis and soil-transmitted helminth (STH) infections that are endemic in this region. Methods This cross-sectional study determined the prevalence, intensity of infection and geographical distribution of schistosome and STH infections among 4,065 children aged 5–19?years in 84 primary schools in Mbita and nearby islands of Lake Victoria (Mfangano, Ringiti, Rusinga and Takawiri), in western Kenya. Single stool samples were collected and examined for eggs of Schistosoma mansoni and STHs (Hookworms, Ascaris lumbricoides and Trichuris trichiura) using the Kato-Katz technique. Primary schools were mapped using geographical information system data on PDAs and prevalence maps generated using ArcView GIS software. Results Overall, 65.6% (95% CI?=?64.2-67.1%) of children were infected with one or more helminth species; 12.4% (95% CI?=?11.4-13.4%) of children were infected with one or more STH species. Mean school prevalence of S. mansoni infection was 60.5% (95% CI?=?59.0-62.0%), hookworms 8.4% (95% CI?=?7.6-9.3%), A. lumbricoides 3.3% (95% CI?=?2.7-3.8%), and T. trichiura 1.6% (95% CI?=?1.2-2.0%). Interestingly, the mean S. mansoni prevalence was 2-fold higher on the islands (82%) compared to the mainland (41%) (z?=?5.8755, P?

Lumbrocoides 3.3％（95％CI？ =？？2.7-3.8％）和T.Trichiura 1.6％（95％CI？=？1.2-2.0％）。有趣的是，与内地（41％）（Z？= 5.8755，P？<0.0001）相比，岛屿的平均S. Mansoni Pevalience在岛上（82％）高2倍（82％）。同样，与内地相比，岛上感染强度为54％（217.2？±99.3）（141.3？±123.7）（z？= 3.9374，p？<0.0001）。最接近维多利亚湖的学校具有最高的S. Mansoni患病率，而STH的流行更加均匀分布。结论MBITA和4个岛屿中血吸虫病的普及率非常令人惊叹，表明控制干预措施紧急和批判。从本次调查中的调查结果表明需要在以前由大众药物管理计划覆盖的偏远地区实施治疗。
