Abstract

BACKGROUND

Intestinal parasitic infections (IPIs) are endemic worldwide and have been the cause of illness and disease worldwide.

OBJECTIVES

The study is aimed to estimate prevalence, intensity, and factors associated with IPIs among school children aged 6-12 years.

MATERIALS AND METHODS

This cross-sectional survey was carried out from February to July 2010, in the diagnostic laboratory of Microbiology department. The study group was divided into four groups, namely, Group A; Group B; Group C; and Group D. A total of 1769 eligible children were enrolled for sampling from these schools. For each enrolled child in the study, a standard stool ova and parasite test with formol-ether concentration technique was done for the assessment of the outcome.

RESULTS

Among 1224 participants, 714 (58.3%) were boys and 508 (41.5%) were girls. The overall prevalence of IPIs was estimated as 51.5%. Group A 84%, Group B 64.7%, Group C 62.4%, and Group D 39.3%. Single IPIs were 65.7%, among which 48% were helminthic and 19.3% were protozoan. Multiple IPIs were 34.2%, among which protozoan along with helminthic were 25.9%, polyhelminthic were 8.5% and polyprotozoan were 4.2%. Among the IPIs detected, overall prevalence of helminth was 75.9%, protozoan was 24.1%. Among the helminthes hookworm was highest (28%). Among the protozoan Entamoeba histolytica/dispar was highest (14.8%).

CONCLUSIONS

The study confirmed that prevalence of IPIs is high as 51.5%. Overall prevalence shows an endemic situation. Therefore, it is recommended that local health sectors should make provision for regular examination of parasitosis and deworming.

摘要

背景

肠道寄生虫感染在全球范围内流行，是全球疾病和健康问题的病因之一。

目的

本研究旨在评估6至12岁学龄儿童肠道寄生虫感染的患病率、感染强度及相关因素。

材料与方法

本横断面调查于2010年2月至7月在微生物学系诊断实验室进行。研究组分为四组，即A组、B组、C组和D组。共从这些学校招募了1769名符合条件的儿童进行抽样。对研究中每名入选儿童，采用甲醛-乙醚浓缩技术进行标准粪便虫卵和寄生虫检测，以评估结果。

结果

1224名参与者中，男孩714名（58.3%），女孩508名（41.5%）。肠道寄生虫感染的总体患病率估计为51.5%。A组为84%，B组为64.7%，C组为62.4%，D组为39.3%。单一肠道寄生虫感染占65.7%，其中48%为蠕虫感染，19.3%为原生动物感染。多重肠道寄生虫感染占34.2%，其中原生动物与蠕虫混合感染占25.9%，多种蠕虫感染占8.5%，多种原生动物感染占4.2%。在检测到的肠道寄生虫感染中，蠕虫的总体患病率为75.9%，原生动物为24.1%。蠕虫中钩虫感染率最高（28%）。原生动物中溶组织内阿米巴/迪斯帕内阿米巴感染率最高（14.8%）。
