Intestinal parasites are important contributors to the global disease burden, especially in children of low-income countries. The present study determined the frequency of intestinal parasites in children hospitalized at the diarrhea section of the Infectious-Contagious Diseases ward and at the Malnutrition ward of the Department of Pediatrics of the Maputo Central Hospital in Mozambique.
This pilot study conducted between February and March 2009 enrolled a total of 93 children between 1.5 and 48.2 months of age; 87.1% were younger than 24 months. Parasite detection in stool samples was achieved using direct microscopic observation and Ritchie's concentration technique.
Infection with pathogenic intestinal parasites was detected in 16.1% (15/93) of the children. Giardia duodenalis and Trichuris trichiura were the most common parasites (6.5%, 6/93 each), followed by Ascaris lumbricoides (2.2%, 2/93). One case of mixed infection with A. lumbricoides plus T. trichiura was also detected.
This study reinforces the importance of routinely examining stool samples for the diagnosis of intestinal parasites (including protozoa) in children hospitalized in endemic areas.
肠道寄生虫是全球疾病负担的重要促成因素，尤其是在低收入国家的儿童中。本研究确定了在莫桑比克马普托中心医院儿科传染病病房腹泻区和营养不良病房住院的儿童中肠道寄生虫的感染率。
这项于2009年2月至3月进行的试点研究共纳入了93名年龄在1.5至48.2个月之间的儿童；87.1%的儿童年龄小于24个月。通过直接显微镜观察和Ritchie浓缩技术对粪便样本进行寄生虫检测。
在16.1%（15/93）的儿童中检测到致病性肠道寄生虫感染。十二指肠贾第虫和毛首鞭形线虫是最常见的寄生虫（各占6.5%，6/93），其次是蛔虫（2.2%，2/93）。还检测到1例蛔虫和毛首鞭形线虫混合感染病例。
本研究强调了在流行地区住院儿童中常规检查粪便样本以诊断肠道寄生虫（包括原生动物）的重要性。
