This is a cross-sectional study that is aimed at evaluating the efficacy of antilice shampoo against head lice infestation in primary schoolgirls at level 3-6 (aged between 9 and 12 years) with a high prevalence of infestation in Pathum Thani Province and which also reported a current prevalence of lice infestation in this school. The study was conducted during January-March 2023. A total of 356 schoolchildren were screened for lice infestation. The prevalence rate of lice infestation was found in 78 students (21.9%) from all schoolchildren. Girls (50.3%) showed a higher rate of lice infestation than boys (0.5%) with a significant difference ( < 0.05). Most lice-infested girls (100%) reported itching. Seventy-two of 77 infested girls (93.5%) agreed to use shampoos for lice treatment. Two types of commercial shampoos were considered for lice treatment: (1) chemical (permethrin 0.5% W/V) antilice shampoo and (2) herbal antilice shampoo, since it is cheap and available in the market. The results of chemical (permethrin 0.5% W/V) antilice shampoo showed similar efficacy for lice treatment as herbal antilice shampoo with no significant difference in statistics ( > 0.05). Using the antilice shampoos consecutively 3 times demonstrated the highest efficacy of treatment (73.0%), followed by 2 times (34.3%), and the lowest efficacy of treatment was a single application (5.6%). No serious side effects from both shampoos in participants: 2 cases of itching and 1 case of the burning sensation. This indicated that in the area of the high prevalence of lice infestation, herbal antilice shampoo might be an alternative choice for lice treatment. However, we recommended using it once a week 3 times consecutively to reach the highest efficacy for treatment. In addition, this treatment should be extended to family members with lice infestation.
这是一项横断面研究，旨在评估抗虱洗发水对佛统府3至6年级（9至12岁）小学女生头虱感染的疗效，该地区头虱感染率较高，且该学校目前也报告了虱子感染率。该研究于2023年1月至3月进行。共对356名学童进行了虱子感染筛查。在所有学童中，发现78名学生（21.9%）有虱子感染率。女孩（50.3%）的虱子感染率高于男孩（0.5%），差异有统计学意义（<0.05）。大多数感染虱子的女孩（100%）报告有瘙痒症状。77名感染虱子的女孩中有72名（93.5%）同意使用洗发水进行虱子治疗。考虑使用两种商业洗发水进行虱子治疗：（1）化学（0.5%W/V氯菊酯）抗虱洗发水和（2）草药抗虱洗发水，因为它价格便宜且在市场上有售。化学（0.5%W/V氯菊酯）抗虱洗发水的治疗效果与草药抗虱洗发水相似，统计学上无显著差异（>0.05）。连续使用抗虱洗发水3次显示治疗效果最高（73.0%），其次是2次（34.3%），治疗效果最低的是单次使用（5.6%）。参与者使用这两种洗发水均未出现严重副作用：2例瘙痒和1例烧灼感。这表明在虱子感染率高的地区，草药抗虱洗发水可能是虱子治疗的替代选择。然而，我们建议连续3次每周使用一次以达到最高治疗效果。此外，这种治疗应扩展到有虱子感染的家庭成员。
