Intestinal parasitic infections among under-five children and maternal awareness about the infections in Shesha Kekele, Wondo Genet, Southern Ethiopia

Background: Few studies have reported the magnitude of intestinal parasitic infections among under-five children in tropical countries. Moreover, there is little information on maternal awareness about intestinal parasitosis.Objective: To determine the prevalence of intestinal parasitosis among under-five children, and assess maternal awareness about it in Shesha Kebkele, Wondo Genet, Southern Ethiopia.Methods: A cross-sectional study involving 288 under-five children was conducted and stool samples were collected and examined for intestinal parasites using Kato-Katz and formol-ether concentration methods. In addition, a total of 130 mothers of under-five children were interviewed regarding their awareness about intestinal parasitic infections.Results: Of the 288 children, 245 (85.1%) were found infected with one or more intestinal parasites. The prevalence of Trichuris trichiura, Schistosoma mansoni and Ascaris lumbricoides, hookworm, and Hymenolepis nana infections as determined by Kato-Katz were 74.7%, 37.2%, 25.7%, 5.9%, and 4.5%, respectively. On the other hand, theprevalence of Strongyloides stercoralis, Giardia lamblia, Entamoeba histolytica/dispar, and Entamoeba coli infections as determined by formol-ether concentration method were 0.69%, 13.2%, 0.35%, and 2.1%, respectively. Most mothers were reasonably aware of the mode of transmission of ascariasis, amoebiasis and giardiasis while they hadvery limited knowledge of bilharzia and hookworm transmission. Almost all of the respondents reported that infections with intestinal parasites could cause retardation of growth and death in children unless treated.Conclusion: Intestinal parasitic infections were prevalent in varying magnitude among under-five children in Wondo Genet area, Southern Ethiopia. Mothers in the study area had a fairly good knowledge of the impact of infections but limited knowledge of the mode of transmission of intestinal parasitic infections. Improvement of sanitation and healtheducation are required besides preventive chemotherapy to control worms (except for schistosomiasis in under-five which need treatment on an individual basis) and other intestinal parasitic infections in the area

PREVALENCE AND RISK FACTORS OF SCHISTOSOMIASIS AMONG HAUSA COMMUNITIES IN KANO STATE, NIGERIA

SUMMARY Schistosomiasis remains one of the most prevalent neglected tropical diseases especially in Nigeria which has the greatest number of infected people worldwide. A cross-sectional study was conducted among 551 participants from Kano State, North Central Nigeria. Fecal samples were examined for the presence of Schistosoma mansoni eggs using the formalin-ether sedimentation method while the urine samples were examined using the filtration technique for the presence of S. haematobium eggs. Demographic, socioeconomic and environmental information was collected using a pre-validated questionnaire. The overall prevalence of schistosomiasis was 17.8%, with 8.9% and 8.3% infected with S. mansoni and S. haematobium, respectively and 0.5% presenting co-infection with both species. The multiple logistic regression analysis revealed that age < 18 years (OR = 2.13; 95% CI; 1.34- 3.41), presence of infected family members (OR = 3.98; 95% CI; 2.13-7.46), and history of infection (OR = 2.87; 95% CI; 1.87- 4.56) were the significant risk factors associated with schistosomiasis in these communities. In conclusion, this study revealed that schistosomiasis is still prevalent among Hausa communities in Nigeria. Mass drug administration, health education and community mobilization are imperative strategies to significantly reduce the prevalence and morbidity of schistosomiasis in these communities
