A descriptive cross-sectional school based study was carried out to investigate the prevalence of soil-transmitted intestinal helminths and the associated factors among school children in Kaduwela Medical Officer of Health (MOH) area in the Colombo district, which was affected by floods in 2016. The study was conducted in 9 selected schools in Kaduwela MOH area from September 2016 to March 2017. Permission was obtained from the relevant authorities. Grade 1 students were enrolled in the study after obtaining informed written consent from their parents/guardian. Interviewer based questionnaire was administered to gather demographic data and other relevant information. Stool samples were collected and examined by direct wet saline smear. Study population comprised 53.4% male students. None of stool samples were positive for soil-transmitted helminths but 17.4% of students complained of nocturnal itching and parents of 23% of them had seen worms passing out from their children's anus at night. Fourteen stool samples were found to be positive for cyst of . Majority of parents (69%) stated that their children always wash their hands with soap and water before meals, whereas 26% stated that their children practice this sometimes. Majority of students (88%) washed their hands after going to the toilet. Almost all students (86%) used water sealed toilets and very few used pit latrines (14%). In this study, 67% of students had received anti-helminthic drugs after the floods. These findings suggest that zero prevalence of helminthic infections could be due to anti-helminthic prophylaxis and good health practices. Further studies should be done in this area with a large sample size to investigate the true prevalence of helminthic infections. Students and parents should be educated on infection. The source of water supply should be tested for fecal contamination.
在科伦坡地区卡杜韦拉卫生医疗官（MOH）辖区开展了一项基于学校的描述性横断面研究，以调查土壤传播的肠道蠕虫病的患病率及其在2016年受洪水影响的学龄儿童中的相关因素。该研究于2016年9月至2017年3月在卡杜韦拉MOH辖区的9所选定学校进行。已获得相关当局的许可。在获得家长/监护人的知情书面同意后，一年级学生被纳入研究。通过基于访谈者的问卷收集人口统计学数据和其他相关信息。收集粪便样本并通过直接湿盐水涂片进行检查。研究人群中男生占53.4%。没有粪便样本检测出土壤传播的蠕虫呈阳性，但17.4%的学生抱怨夜间瘙痒，其中23%学生的家长曾在夜间看到有虫子从孩子肛门排出。发现14份粪便样本的 囊肿呈阳性。大多数家长（69%）表示他们的孩子总是在饭前用肥皂和水洗手，而26%的家长表示他们的孩子有时会这样做。大多数学生（88%）在如厕后洗手。几乎所有学生（86%）使用水封式厕所，很少有人使用坑式厕所（14%）。在这项研究中，67%的学生在洪水后接受了抗蠕虫药物治疗。这些发现表明，蠕虫感染零患病率可能归因于抗蠕虫预防措施和良好的健康习惯。应在该地区进行更大样本量的进一步研究，以调查蠕虫感染的真实患病率。应就感染问题对学生和家长进行教育。应对供水水源进行粪便污染检测。
