During the period of insurgency there were several internally displace people camps all over the Northern Uganda. People who lived within ten kilometers from Gulu Municipality were forced to evacuate their villages and re-locate and build huts for themselves in areas identified for them by the government. There were several of such camps within the municipality creating influx of people from the villages to the municipality for security. Now with the situation restored to normal, there is need to re-assess and update information on the prevalence of helminth infections in Gulu municipality where many of the internally displaced people (IDP) settled.
To find out if S. mansoni and soil transmitted nematode infections are so prevalent and very common in children aged betweenfive to 20 years. In Gulu municipality and that additional preventive and curative measure need to be considered. Further is there a strong need to reconsider more sensitive diagnostic methods at the hospitals or does the standard approach of direct smear examination recognise at least most heavy infected children with any of the parasites. Setting. The study was carried out in Gulu municipality.
Purposive and random sampling methods were used. Study Population: Mainly Primary school children aged between five to 20 years randomly selected from four primary schools purposively selected around Gulu municipality were recruited for the study. For control 20 staff of each school randomly selected were also studied.
Of the 582 samples tested, 117(20.1%) were found positive for Schistosoma mansoni. Fifteen (2.6%) other samples were found positive for other helminths like Ascaris lumbricoides, Trichuris trichiura H.nana Hookworm. The comparison between the methods showed that the results obtained by the three methods were similar for field research. There is a low intensity of infection with soil transmitted helminths found in the primary schools around Gulu municipality.
We concluded that the prevalence and intensity of infection with soil transmitted helminths was low among the children aged between 5 to 20 years in the four primary school studied (2.6%) but there was medium infection with S.mansoi (20.1%). The sensitivity in detecting the helminthes eggs in the stool specimen were similar. Though the original Kato/Katz method recorded lowest egg count than the Polderman and Odongo-Aginya methods. This could be due to the fact that the slides were read immediately.
在叛乱期间,乌干达北部各地有多个境内流离失所者营地。居住在距古卢市10公里范围内的人们被迫撤离村庄,在政府为他们指定的地区重新安置并建造棚屋。市内有几个这样的营地,导致村民为了安全涌入该市。现在局势已恢复正常,有必要重新评估和更新关于古卢市(许多境内流离失所者定居于此)蠕虫感染流行情况的信息。
了解曼氏血吸虫和土壤传播线虫感染在5至20岁儿童中是否如此普遍和常见。在古卢市,是否需要考虑额外的预防和治疗措施。此外,是否迫切需要重新考虑医院更敏感的诊断方法,或者直接涂片检查的标准方法是否至少能识别出大多数感染任何一种寄生虫的重度感染儿童。地点:该研究在古卢市进行。
采用了目的抽样和随机抽样方法。研究人群:主要从围绕古卢市有目的地挑选出的四所小学中随机抽取年龄在5至20岁的小学生作为研究对象。作为对照,还对每所学校随机挑选的20名工作人员进行了研究。
在检测的582个样本中,117个(20.1%)曼氏血吸虫检测呈阳性。另外15个(2.6%)样本其他蠕虫如蛔虫、鞭虫、微小膜壳绦虫、钩虫检测呈阳性。方法之间的比较表明,三种方法在实地研究中获得的结果相似。在古卢市周边小学发现土壤传播蠕虫的感染强度较低。
我们得出结论,在所研究的四所小学中,5至20岁儿童土壤传播蠕虫的感染率和感染强度较低(2.6%),但曼氏血吸虫感染为中度(20.1%)。粪便标本中检测蠕虫卵的敏感性相似。尽管原始的加藤/凯茨方法记录的虫卵计数低于波尔德曼和奥东戈 - 阿吉尼亚方法。这可能是因为玻片是立即读取的。
