This study aimed to investigate the prevalence of infestation and its associated factors among primary school children (PSC) in the Rufiji district.
A quantitative school-based cross-sectional study was conducted among 447 PSC in the Rufiji district. The prevalence of scabies among PSC was determined by clinical examination and by microscopic examination of skin samples for the presence of . A structured questionnaire was used to gather data on factors associated with infestation. Descriptive analysis, Fisher's exact, chi-square tests, and logistic regression analysis were used to analyze the data.
The prevalence of scabies was 2.0%. Of the assessed factors, only physical contact with a person having itchy skin lesions (Adjusted Odds Ratio [AOR]=4.04, 95%CI 4.39-12.50) and infrequency of changing clothes before laundry (AOR=2.99, 95%CI 1.35-4.94) were significantly associated with scabies. The majority of participants demonstrated low levels of knowledge, with half exhibiting poor attitudes and inappropriate healthcare-seeking behaviors.
There was an ongoing transmission of scabies among PSC in the Rufiji district, with the factors associated with the transmission being physical contact with a person who had an itchy skin lesion and the infrequency of changing clothes before laundry. Therefore, there is a need for regular clinical screening and treatment of positive cases with preventive measures on contact and provision of health education.
本研究旨在调查鲁菲吉区小学生疥疮感染率及其相关因素。
在鲁菲吉区的447名小学生中开展了一项基于学校的定量横断面研究。通过临床检查以及对皮肤样本进行显微镜检查以确定疥螨的存在，从而确定小学生疥疮的感染率。使用结构化问卷收集与疥疮感染相关因素的数据。采用描述性分析、Fisher精确检验、卡方检验和逻辑回归分析对数据进行分析。
疥疮感染率为2.0%。在评估的因素中，只有与有皮肤瘙痒性病变的人发生身体接触（调整优势比[AOR]=4.04，95%置信区间4.39 - 12.50）以及洗衣前不常换衣服（AOR=2.99，95%置信区间1.35 - 4.94）与疥疮显著相关。大多数参与者知识水平较低，一半人态度不佳且有不恰当的就医行为。
鲁菲吉区小学生中存在疥疮的持续传播，传播相关因素为与有皮肤瘙痒性病变的人发生身体接触以及洗衣前不常换衣服。因此，需要对阳性病例进行定期临床筛查和治疗，并采取接触预防措施以及提供健康教育。
