Abstract Background: Schistosomiasis control programmes primarily use school-based surveys to identify areas for mass drug administration of preventive chemotherapy. However, as the spatial distribution of schistosomiasis can be highly focal, transmission may not be detected by surveys implemented at districts or larger spatial units. Improved mapping strategies are required to accurately and cost-effectively target preventive chemotherapy to remaining foci across all possible spatial distributions of schistosomiasis. Methods: Here, we use geostatistical models to quantify the spatial heterogeneity of Schistosoma haematobium and S. mansoni across sub-Saharan Africa using the most comprehensive dataset available on school-based surveys. Applying this information to parameterise simulations, we assess the accuracy and cost of targeting alternative implementation unit sizes across the range of plausible schistosomiasis distributions. We evaluate the consequences of decisions based on survey designs implemented at district and subdistrict levels sampling different numbers of schools. Cost data were obtained from field surveys conducted across multiple countries and years, with cost effectiveness evaluated as the cost per correctly identified school. Results: Models identified marked differences in prevalence and spatial distributions between countries and species; however, results suggest implementing surveys at subdistrict level increase the accuracy of treatment classifications across most scenarios. While sampling intensively at the subdistrict level resulted in the highest classification accuracy, this sampling strategy resulted in the highest costs. Alternatively, sampling the same numbers of schools currently recommended at the district level but stratifying by subdistrict increased cost effectiveness.Conclusions: This study provides a new tool to evaluate schistosomiasis survey designs across a range of transmission settings. Results highlight the importance of considering spatial structure when designing sampling strategies, illustrating that a substantial proportion of children may be undertreated even when an implementation unit is correctly classified. Control programmes need to weigh the increased accuracy of more detailed mapping strategies against the survey costs and treatment priorities.

Background: Sub-Saharan Africa faces by far the highest rate of HIV and other Sexually Transmitted Infections (STIs). Illegal mineworkers are considered at risk for HIV and sexually transmitted infections (STIs). Men are generally not receptive to health promotion messages.Methods: This study explored the enablers of sexually transmitted infections. The study utilized a qualitative approach. A total of 40 participants were recruited. Semi structured interviews were used to collect data. A thematic approach was used to analyze the data. Zimbabwe, like any other country in the sub-Saharan region of Africa, has been affected by the epidemic of HIV/AIDS and other STIs, because of poor sexual health education.Results: The study found that the enablers of STIs included poor sexual health knowledge, substance misuse, prolonged stay from family, stigma, lack of entertainment, cultural status, and poor sexual health services.Conclusions: STIs among illegal gold miners is a public health concern that needs urgent attention in many developing countries.
