Intestinal parasitic infections and associated factors among street dwellers' in Dessie town, North-East Ethiopia: a cross sectional study

Abstract

Objective: Intestinal parasitic infections are among the major cause of diseases of public health problems in sub-Saharan Africa. In Ethiopia, epidemiological information on street dwellers is very limited. So, this study aimed to determine the prevalence and associated factors of intestinal parasite among street dwellers' in Dessie town, North-East, Ethiopia.

Results: A cross-sectional study was carried out on street dwellers in Dessie town from November 2017 to February, 2018. Stool specimen was examined by direct wet mount, formol-ether concentration technique and modified Ziehl-Neelsen methods. Majority of study participants were males 220 (89.4%). The mean age of the study participants were 22.85 (SD = 4.78) years. The overall parasite prevalence was 108/246 (43.9%). Among the six different intestinal parasites detected, H. nana 33 (13.4) and E. histolytica 24 (9.8%) were dominant. Multivariate analysis showed, shoe wearing habit (P = 0.035), hand washing habit after toilet (P = 0.035), and history of animal contact (P = 0.016) had statistically significant association with intestinal parasitic infections after adjusting other variables. Although the prevalence of intestinal parasitic infections in this study was lower than previous studies conducted in similar study groups. The prevention and control strategies of intestinal parasites should address the poor segment of populations including street dwellers.
