Prevalence and risk factors associated with Entamoeba Histolytica infection among children in Sebha, Libya

Abstract

Background: The protozoa parasite Entamoeba histolytica is an important cause of human morbidity and mortality worldwide besides malaria and schistosomiasis. Prevalence of E. histolytica in Sebha, Libya has been scantily studied and risk factors associated with this parasite are unavailable in Libya. Aims: A cross-sectional study was aimed to provide the first data on the prevalence and epidemiological risk factors associated with E. histolytica infection among school children in Sebha, Libya. Subjects and Methods: A total of 150 stool samples randomly were collected (during period from April 2017 to May 2017) from school children residents of Sebha and examined by direct smear microscopy (in normal saline and iodine smears) for the detection of E. histolytica infection. Results: Of one hundred fifty children, six children (4%) were found to be infected with this parasite. Boys were more significantly (P 0.05). It has been noted that those who had large family size have significantly (P < 0.05) higher risk of being infected with E. histolytica. A significant (P < 0.05) association was found between education level of children's parents and E. histolytica exposure among children. No, significant correlation was found between monthly income of family and the presence of E. histolytica infection among children. Conclusions: Prevalence of E. histolytica among school children is low and this parasite may play a minor role in causing morbidity in this population in Sebha, Libya. Large size of families and education of parents of children were significant predictors of this parasite. In addition, more studies are needed to provide data on epidemiological risk factors of E. histolytica to improve health education and environmental sanitary conditions to protect children from the infection of this parasite in Libya.
