Observational study finds dispersed dengue transmission despite improving larval indices in endemic areas, highlighting persistent environmental risks for mosquito-borne outbreaks.

Key Points

To spatially analyze environmental factors and vector indicators associated with dengue case distribution across an endemic health center catchment area during 2022–2023.
Conducted an observational, qualitative exploratory study utilizing geographic information systems (GIS) software to analyze spatial distribution patterns of dengue cases.
Collected primary indoor temperature and relative humidity data alongside secondary records of rainfall, larval-free index (LFI), larval density, and case numbers.
Reported dengue cases declined by 61% between 2022 and 2023, while indoor microclimates averaged 31°C and 70% relative humidity.
Separated transmission patterns (>100 m radius) dominated in both years, accounting for 55% of cases in 2022 and 60% in 2023.
Rainfall correlated inversely with cases in 2022 but was inconsistent in 2023, whereas all sub-districts met larval-free index targets in 2023 after one sub-district failed in 2022.
