Modeling dataset on Biomphalaria spp. snail hosts in sub-Saharan Africa (Uganda, DRC and Chad): snail occurrence, environmental, geomorphological, and detection variables

It includes repeated observations from freshwater human water-contact sites, along with associated metadata relevant to detection and analysis, such as date, time, observer information, site delineation, and linked environmental covariates.

Because the data were generated through community-based monitoring across contrasting ecological settings, users should account for uneven sampling effort, strong between-site heterogeneity, class imbalance, and context-specific relationships when using the dataset for inference or prediction.</p>
