摘要

背景:在卫生设施差的国家,寄生虫感染是一个公共卫生问题。然而,关于埃塞俄比亚亚的斯亚贝巴Akaki河沿岸农户中废水和土壤样本中的蠕虫与蠕虫感染率之间的流行病学关联的信息很少。方法:在2021年11月至2022年2月期间进行横断面研究。采用分层随机抽样方法对农户进行抽样。每个地区的样本量由按比例分配的家庭数量决定。从废水灌溉农场收集了70份废水样本、28份土壤样本和86份农民粪便样本,并对其进行了蠕虫分析。使用问卷收集有关农户的人种学数据,而使用废水和土壤样本分析来生成关于蠕虫负荷的定量数据。通过开发主题对数据进行系统分析,并使用三角测量验证方法评估偏倚。通过测量来评估寄生虫感染的潜在途径。采用泊松回归法对污水、土壤样品和农民粪便中的蠕虫卵总数进行了调查。结果:82.9%的污水样本、57.1%的土壤样本和18.6%的农民粪便样本中含有蠕虫卵。所有样本中最常见的蠕虫是类蚓蛔虫(废水67%,土壤25%,粪便10.5%),其次是钩虫(废水10%,土壤21.4%,粪便6.9%)和毛滴虫卵(废水5.7%,土壤10.7%,粪便1.2%)。污水中虫卵总数、土壤样品中虫卵总数与农民粪便中虫卵数呈正相关。废水和土壤的泊松回归系数分别为1.63 (95% CI = 1.34 ~ 1.92)和1.70 (95% CI = 1.39 ~ 2.01)。(p)结论:赤明河流域废水和土壤样品中总虫卵与农民粪便有明显的相关性。因此,必须采取综合办法来解决这一领域的问题,防止寄生虫感染进一步蔓延。

Distribution of helminth eggs in environmental and stool samples of farming households along Akaki River in Addis Ababa, Ethiopia.

Background: Helminth infections are a public health issue in countries with poor sanitation facilities. However, there little information on the epidemiological association between helminths in wastewater and soil samples and rates of helminth infection among farming households along the Akaki River in Addis Ababa, Ethiopia.

Methods: A cross-sectional study was conducted between November 2021 and February 2022. A stratified random sampling technique was used to select farming households. The sample size for each district was determined by a proportionate allocation to the number of households. From wastewater-irrigated farms, 70 wastewater samples, 28 soil samples, and 86 farmers' stool samples were collected and analyzed for helminths. A questionnaire was used to gather ethnographic data, about farming households, whereas wastewater and soil sample analysis was used to generate quantitative data on helminth loads. The data were systematically analysed by developing themes, and bias evaluated using triangulation validation methodologies. Potential pathways to helminth infection were evaluated by measuring. Total number of helminth eggs in wastewater, soil samples and farmer's stools was investigated using Poisson regression.

Results: In this study, 82.9% of wastewater samples, 57.1% of soil samples, and 18.6% of farmers' stool samples contained helminth eggs. The most prevalent helminth was Ascaris lumbricoides in all samples (wastewater 67%, soil 25%, and stool 10.5%), followed by hookworm (wastewater 10%, soil 21.4%, and stool 6.9%) and Trichuris trichiura eggs (wastewater 5.7%, soil 10.7%, and stool 1.2%). There was a positive association between the total number of helminth eggs in wastewater and soil samples with counts in farmers' stool. The Poisson regression coefficients for wastewater and soil were, 1.63 (95% CI = 1.34-1.92) and 1.70 (95% CI = 1.39-2.01), (p < 0.05).

Conclusions: This research has shown a clear association between the total helminth eggs in wastewater and soil samples and farmer stools along the Akaki River. Therefore, an integrated approach is essential to address the issue in this area and prevent the spread of further helminth infections.
