Prevalence of intestinal parasitic helminths and its associated risk factors in Mekaneselam Town, South Wollo, Ethiopia.

Background: Intestinal parasitic (IP) infections caused by helminths are among the most significant public health concerns that mainly affect deprived people in Sub-Sahara African countries. The current study aimed to determine the prevalence and associated risk factors of intestinal parasitic helminths among patients attending Mekaneselam hospital. Method: In this cross-sectional study conducted from August 2022 to February 2023, stool specimens were collected and examined microscopically to detect intestinal helminths using direct wet-mount and formal-ether concentration techniques. A structured questionnaire was employed to obtain information regarding the socio-demographic characteristics and associated risk factors. Data were analyzed via appropriate univariate and multivariable logistic regression methods using SPSS version 25.0. Result: The overall prevalence of the parasitic helminths was 51 (12.6%) out of 404 patients attending in Mekaneselam town during the study period. In this study, seven species of intestinal helminths were detected, with Ascaris lumbricoides (5.7%) being the most prevalent followed by Trichuris trichiura (2.2%). Significant positive associations were observed between intestinal helminths infection and the socio-demographic characteristics including marital status (χ² = 7.97, p = 0.047), educational level (χ² = 9.34, p = 0.025) and residence (χ² = 3.90, p = 0.048). The odds of being infected with IP were three times higher among divorced patients than married individuals (AOR = 3.21, CI = 1.15–8.96, p = 0.03). Illiterate individuals were three times (AOR = 2.61, CI = 1.24–5.49, p = 0.011) and those who attended primary school were two times (AOR = 2.3, CI = 1.029–5.143, p = 0.042), more likely to have helminthic infections. Participants who did not wash their hands after using the toilet were five times more likely to acquire IP helminths than those who did (AOR = 4.36, CI = 2.83–6.72, p = 0.000). In the case of the feeding habit, study subjects who ate unwashed vegetables were more likely to acquire helminths than those who did not eat unwashed vegetables (AOR = 5. 43, CI = 4.33–23.77, p = 0.000). Conclusion: This study highlighted a substantial prevalence of intestinal helminths infections (12.6%) in the study area, warranting the urgent need for attention and interventions from relevant public health authorities.
