Assessment of awareness and knowledge of schistosomiasis among school-aged children (6–13 years) in the Okavango Delta, Botswana

Background: Schistosomiasis is a global health problem affecting 250 million people, with 90% in Sub-Saharan Africa. In Botswana, the burden is high in the Okavango delta because of the water channels. WHO recommends integrated measures, including access to clean water, sanitation, health education, and drugs to control and eliminate schistosomiasis. Gauging knowledge and awareness of schistosomiasis for School-Aged Children (SAC) is crucial. Our study aimed at assessing knowledge and awareness of schistosomiasis among SAC in the Okavango Delta. Methods: A cross-sectional survey assessing awareness and knowledge of schistosomiasis in schools was conducted. 480 questionnaires were administered to gather demographic profiles, awareness, and knowledge of risky behaviors. Chi-square and descriptive analysis determined the differences in SAC`s awareness and knowledge levels based on localities, gender, age, and health education. Results: The results showed a low awareness level, with only (42%) of respondents having heard about the disease and (52%) knowing its local name. Younger children from Sekondomboro (83%) and Samochima lacked awareness, while children from Mohembo (77%) and those who had health education (70%) demonstrated significant awareness levels (P ≤ 0.001). Seventy-two percent (72%) lacked knowledge of the cause and (95%) did not know the disease life-cycle. Children from Xakao (91%), (85%) Sepopa, and (75%) of younger children did not know haematuria is a symptom of the disease. Older and SAC with health education were more likely to know that swimming is a risk factor (P ≤ 0.001) and (P ≤ 0.05) respectively. Conclusions: Although respondents from four schools demonstrated some level of awareness of the disease, and knowledge of risky behaviors, the study showed a lack of in-depth knowledge on the life-cycle and cause of the diseases. We, therefore, recommend the implementation of an integrated approach to health education and improvement in access to clean water and sanitation in all study areas

A mixed method analysis of the Botswana schistosomiasis control policy and plans using the policy triangle framework

Abstract Background The present goal of the World Health Organization (WHO) 2021–2030 roadmap for Neglected Tropical Diseases is to eliminate schistosomiasis as a public health problem, and reduce its prevalence of heavy infections to less than 1%. Given the evolution and impact of schistosomiasis in the Ngamiland district of Botswana, the aim of this study was to analyze the control policies for the district using the Policy Triangle Framework. Methods The study used a mixed method approaches of an analysis of policy documents and interviews with 12 informants who were purposively selected. Although the informants were recruited from all levels of the NTD sector, the analysis of the program was predominantly from the Ngamiland district. Data were analyzed using Braun and Clarke’s approach to content analysis. Results The study highlights the presence of clear, objectives and targets for the Ngamiland control policy. Another theme was the success in morbidity control, which was realized primarily through cycles of MDA in schools. The contextual background for the policy was high morbidity and lack of programming data. The implementation process of the policy was centralized at the Ministry of Health (MOH) and WHO, and there was minimal involvement of the communities and other stakeholders. The policy implementation process was impeded by a lack of domestic resources and lack of comprehensive policy content on snail control and no expansion of the policy content beyond SAC. The actors were predominately MOH headquarters and WHO, with little representation of the district, local level settings, NGOs, and private sectors. Conclusions The lack of resources and content in the control of environmental determinants and exclusion of other at-risk groups in the policy, impeded sustained elimination of the disease. There is a need to guide the treatment of preschool-aged children and develop national guidelines on treating foci of intense transmission. Moreover, the dynamic of the environmental transmissions and reorientation of the schistosomiasis policy to respond to the burden of schistosomiasis morbidity, local context, and health system context are required

The prevalence of urogenital and intestinal schistosomiasis among school age children (6-13 years) in the Okavango Delta in Botswana.

This study sought to investigate prevalence of urogenital and intestinal schistosomiasis among school age children 6-13 years in selected communities in the Okavango Delta. The termination of the Botswana national schistosomiasis control program in 1993 contributed to its neglect. An outbreak of schistosomiasis in 2017 at one of the primary schools in the northeastern part of the country resulted in 42 positive cases, indicating that the disease exists. A total of 1,611 school age children 6-13 years were randomly selected from school registers in 10 primary schools; from which 1603 urine and 1404 stool samples were collected. Macroscopic examination of urine and stool for color, odor, blood; viscosity, consistency, and the presence of worms. Urine filtration and centrifugation methods were used to increase sensitivity of detecting parasite ova. Kato-Katz and Formalin-Ether were used for the examination of stool samples. Data were analyzed using SPSS version 25. Results were expressed as odds ratio (OR) with their 95% CI and statistical significance set at p < 0.05. A total of (n = 1611) school age children 6-13 years participated in the study, mean age 9.7years (SD 2.06), females (54%) and males (46%). Results indicated an overall prevalence of SS. hematobium and S.mansoni at 8.7% and 0.64% respectively. Intensity of SS. hematobium was generally light (97.6%) and heavy intensity (2.4%). Results also revealed a knowledge deficit, about 58% of children had never heard of bilharzia even though they lived in communities where the disease was previously endemic. Learners who had a family member who previously suffered from schistosomiasis had higher knowledge than those who did not. Interestingly, these learners were likely to engage in risky behaviors compared to those with lower knowledge of the disease. An integrated approach that emphasizes health education, mass drug administration, water, sanitation, and hygiene infrastructure should be prioritized for prevention and control of schistosomiasis
