Although the Democratic Republic of Sao Tome and Principe (DRSTP) has undertaken school children-based deworming programs against intestinal parasitic infections (IPIs) using a single dose of mebendazole annually since 2005, it remains unclear as to the outcome to date. The present study intends to investigate the recent IPIs status among school children living in capital areas of the DRSTP.
A total of 252 school children (121 boys and 131 girls) of grades 4 and 5 from 4 primary schools located in the capital areas participated in the present study and their fresh fecal specimens were examined for the presence of any parasites using the merthiolate-iodine-formaldehyde concentration method as conducted.
The overall prevalence of IPIs was 64.7% (163/ 252). No significant gender difference in prevalence between boys (67.8%) and girls (61.8%) was found (p = 0.3). The majority of school children were infected with a single species of parasite (55.8%). Altogether, 12 different intestinal parasite species were identified in DRSTP school children, of which 9 species were pathogenic and the remaining 3 were non-pathogenic.
Improving the detection method, sanitation facilities and personal hygiene as well as utilizing combined drugs are all important measures to greatly reduce IPIs in DRSTP school children.
尽管圣多美和普林西比民主共和国（DRSTP）自2005年以来每年都针对在校儿童开展使用单剂量甲苯咪唑的肠道寄生虫感染（IPIs）驱虫计划，但迄今为止的结果仍不清楚。本研究旨在调查DRSTP首都地区在校儿童近期的IPIs状况。
来自首都地区4所小学的252名4年级和5年级在校儿童（121名男孩和131名女孩）参与了本研究，并按照所采用的硫柳汞 - 碘 - 甲醛浓缩法对他们的新鲜粪便标本进行寄生虫检测。
IPIs的总体患病率为64.7%（163/252）。未发现男孩（67.8%）和女孩（61.8%）在患病率上有显著性别差异（p = 0.3）。大多数在校儿童感染的是单一寄生虫种类（55.8%）。在DRSTP在校儿童中共鉴定出12种不同的肠道寄生虫种类，其中9种具有致病性，其余3种无致病性。
改进检测方法、卫生设施和个人卫生以及使用联合药物都是大幅降低DRSTP在校儿童IPIs的重要措施。
