BACKGROUND/PURPOSE: Pediculus capitis is the most common human ectoparasite. When it feeds on the blood through the scalp of its host, the anticoagulant in its saliva causes scalp inflammation and itching, and consequent scratching by the host causes further inflammation from bacterial infection. P. capitis infestation is currently a common parasitic dermatosis and a critical public health concern in underdeveloped countries.
Through naked eye inspection of P. capitis on or in the hair from 323 school children in Cambodia.
A total of 143 children (44.3%) were found to have P. capitis infestation. Univariate analysis revealed that girls had a significantly higher infection rate than boys. Overall, young aged schoolchildren (10 yrs old ≤) showed significantly higher infection rate than old aged schoolchildren (>10 yrs old). Groups stratified by time revealed that schoolchildren studied at the afternoon classes than morning classes in Tuol Prum Muoy Primary School had a significantly higher risk in acquisition of P. capitis infestation. Multivariate analysis results indicated that relative to the boys, the girls were at a significantly higher risk of contracting P. capitis infection. When stratified by inspection time with the Tuol Prum Muoy Primary School morning classes as the reference, the Tuol Prum Muoy Primary School afternoon classes exhibited a significantly higher risk of P. capitis infection.
Primary school children in Cambodia have a high P. capitis infection rate and thus require effective treatment and prevention measures to treat symptoms and lower the infection rate.
背景/目的：头虱是最常见的人体寄生虫之一。当它通过宿主头皮吸食血液时，其唾液中的抗凝剂会引起头皮炎症和瘙痒，而宿主的搔抓则会导致细菌感染进一步加重炎症。头虱感染目前是一种常见的寄生虫性皮肤病，也是欠发达国家的一个重要公共卫生问题。
通过肉眼检查柬埔寨 323 名学童头发上或头发内的头虱。
共有 143 名儿童（44.3%）被发现患有头虱感染。单因素分析显示，女孩的感染率明显高于男孩。总体而言，年轻的学龄儿童（10 岁及以下）的感染率明显高于年长的学龄儿童（>10 岁）。按时间分层的组显示，图鲁姆莫伊小学下午班的学生比上午班的学生在获得头虱感染方面的风险显著更高。多因素分析结果表明，与男孩相比，女孩感染头虱的风险明显更高。当以图鲁姆莫伊小学上午班为参照，按检查时间分层时，图鲁姆莫伊小学下午班感染头虱的风险显著更高。
柬埔寨的学龄儿童头虱感染率较高，因此需要采取有效的治疗和预防措施来缓解症状和降低感染率。
