Study Overview
Brief Summary
This study tests whether a neighbourhood early-warning and vector-control programme reduces laboratory-confirmed dengue incidence during the monsoon season in dense urban wards of Dhaka.
Detailed Description
Wards are randomised to the intervention or usual care. The intervention combines weekly larval surveillance, community alerts, and targeted source reduction. Incidence is tracked through sentinel clinics and laboratory confirmation over one transmission season.
