Snail Vector Survey for Schistosomiasis Transmission in Western Kenya

Western Kenya's Kakamega and Bungoma counties were surveyed to confirm active schistosomiasis transmission. The dataset contains results from a malacology survey of 4,245 snails collected near 42 primary schools, identifying species and infection prevalence. It was authored by Maurice R. Odiere and last updated in May 2026.

Use Cases

• Modeling schistosomiasis transmission risk based on snail species abundance and infection rates.
• Analyzing the correlation between water body type and snail vector prevalence.
• Mapping vector distribution for targeted snail control interventions in endemic regions.

Strengths

• Contains specific counts for 4,245 snails collected, with 3,341 identified as Biomphalaria pfeifferi.
• Reports infection prevalence with confidence intervals, such as 2.6% of B. pfeifferi shedding cercariae.
• Geographic specificity is high, with sampling tied to 42 primary schools across 19 Wards.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the focused survey in two Kenyan counties.
