Increased Prevalence of Cestode Infection Associated with History of Deworming among Primary School Children in Ethiopia.

Increased Prevalence of Cestode Infection Associated with History of Deworming among Primary School Children in Ethiopia. Am J Trop Med Hyg. 2019 Jul 22;: Authors: Mohamed N, Muse A, Wordofa M, Abera D, Mesfin A, Wolde M, Desta K, Tsegaye A, Taye B Abstract Mass deworming of school-aged children with anthelmintics has been recognized as an effective approach for reducing the burden of soil-transmitted helminth (STH) infections. However, the consequences of this intervention on nontargeted parasite populations sharing the same gastrointestinal niche are unclear. We conducted a cross-sectional survey among three primary schools in Sululta town, Ethiopia, to examine the association between students' histories of deworming treatment in the past 6 months and the prevalence of cestode and protozoan infections. An interviewer-led questionnaire administered to parents provided information on sociodemographic factors, and deworming status was ascertained from school records. Stool samples were collected from 525 children for microscopic examination. The independent associations of "any cestode" (positive either for Hymenolepis nana or Taenia spp. eggs) and "any protozoan" (positive either for Giardia lamblia or Entamoeba histolytica/Entamoeba dispar) with history of deworming were examined using logistic regression. Overall, 25.9% of children were infected with at least one intestinal parasite of which H. nana was the most common. In multivar...
