A cross-sectional study of the prevalence, intensity and effects of soil-transmitted helminth and protozoan infections was undertaken among patients at the Buea Hospital Annex located in Buea sub-division of Cameroon. Stool samples from 356 subjects (174 males and 182 females) were collected and processed using standard concentration methods. Our results showed that 31.0% of subjects were infected with intestinal helminths and the prevalence was higher in females (32.4%) than in males (30.5%). A significantly higher prevalence was observed in rural (47.2%) than in urban areas (21.0%); significance < 0.1%. Prevalence was highest among those aged between 6 and 12 years (41.4%). The total prevalence of intestinal helminth infections were 19.3% for Ascaris lumbricoides, 14.0% for hookworm and 11.8% for Trichuris trichiura. The intensity of infection was unevenly distributed, with very heavy loads concentrated in a few individuals. Data also showed that 28.1% (100/356) of the subjects were infected with protozoans. Females showed a higher prevalence (28.6%; 52/182) than males (20.7%; 36/174). Also, there was a significantly higher prevalence in rural (34.0%; 49/144) than urban areas (18.4%; 39/212); significance < 0.1%. The age group 6-12 years again had a higher prevalence (37.1%; 26/70). The total prevalence of intestinal protozoans was: Entamoeba histolytica (24.4%), Entamoeba coli (11.2%) and Giardia lamblia (0.6%). These relatively heavy prevalences in patients may be reduced by appropriate medication and maintaining strict personal hygiene. Health education, clean water supply, good sewage management and a congenial environment will all help to minimize infection.
在喀麦隆布埃亚分区的布埃亚医院分院，对土壤传播的蠕虫和原生动物感染的患病率、感染强度及影响进行了一项横断面研究。收集了356名受试者（174名男性和182名女性）的粪便样本，并采用标准浓缩方法进行处理。我们的结果显示，31.0%的受试者感染了肠道蠕虫，女性患病率（32.4%）高于男性（30.5%）。农村地区（47.2%）的患病率显著高于城市地区（21.0%）；显著性<0.1%。6至12岁人群的患病率最高（41.4%）。蛔虫感染的总患病率为19.3%，钩虫为14.0%，鞭虫为11.8%。感染强度分布不均，非常高的负荷集中在少数个体中。数据还显示，28.1%（100/356）的受试者感染了原生动物。女性患病率（28.6%；52/182）高于男性（20.7%；36/174）。此外，农村地区（34.0%；49/144）的患病率显著高于城市地区（18.4%；39/212）；显著性<0.1%。6至12岁年龄组的患病率再次较高（37.1%；26/70）。肠道原生动物的总患病率为：溶组织内阿米巴（24.4%）、结肠内阿米巴（11.2%）和蓝氏贾第鞭毛虫（0.6%）。通过适当用药和保持严格的个人卫生，患者中这些相对较高的患病率可能会降低。健康教育、清洁的供水、良好的污水处理和适宜的环境都将有助于减少感染。
