Schistosomiasis and Snail Ecology Surveys Across 116 Villages in Northern Senegal

116 villages in northern Senegal were surveyed for environmental and parasitological data related to schistosomiasis transmission. The dataset includes parasitological surveys of 1,385 schoolchildren from a random subset of 29 villages, alongside ecological surveys quantifying intermediate host snail abundance, infection, aquatic vegetation, debris, and water characteristics. It was authored by Sidy Bakhoum and last updated on 2026-06-04.

Use Cases

• Modeling spatial risk of Schistosoma haematobium infection based on proximity to water-contact sites and village characteristics.
• Analyzing environmental predictors, such as submerged aquatic vegetation and anthropogenic debris, for snail abundance and infection.
• Comparing transmission drivers between S. haematobium and S. mansoni based on ecological and demographic factors.
• Assessing the impact of hydrological infrastructure, like the Diama Dam, on schistosomiasis prevalence patterns.

Strengths

• Includes data from 116 villages and parasitological surveys of 1,385 schoolchildren, providing a substantial sample.
• Integrates multiple data types: human infection prevalence, snail ecology, and physicochemical water characteristics.
• Uses spatial analyses and generalized linear mixed-effects models, suggesting a structured analytical approach.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is specific to the Senegal River Basin; generalizability to other regions may be limited.
