Mouza-Level Visceral Leishmaniasis Cases in Bangladesh, 2017-2025

A micro-stratification dataset maps the endemicity of visceral leishmaniasis (Kala-azar) across 17,123 Mouzas in Bangladesh from January 2017 to June 2025. It was created by Shomik Maruf using national DHIS2 line-list data and categorizes Mouzas as high, moderate, low, or non-endemic based on case counts. The data shows transmission is intensely focal, with only 2.8% of Mouzas reporting cases.

Use Cases

• Identifying high-risk clusters for targeted indoor residual spraying based on endemicity categories.
• Guiding resource allocation for active case detection based on Mouza-level risk maps.
• Monitoring the reduction of endemic areas over time to assess elimination progress.
• Informing post-validation surveillance strategies in other countries approaching VL elimination.

Strengths

• Provides granular, Mouza-level data for 17,123 administrative units.
• Covers a nine-year period from January 2017 to June 2025.
• Categories endemicity based on specific case count thresholds (≥3, 2, 1, 0).
• Identifies that high-endemic Mouzas (33 units) accounted for 35% of total incident cases.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small (5.5 KB), indicating limited scope or aggregated summary data.
