Spatial Patterns of Dengue Incidence in Nepal During Record Outbreaks in 2022 and 2023: Implications for Public Health Interventions.

ABSTRACT: Dengue, which was first reported as a travel case in Nepal in 2004, was initially confined to the lower plains but has spread to higher elevations. Large outbreaks in 2022 and 2023 (54,784 and 51,243 cases, respectively), reached every district (n = 77). We calculated the district-wise incidence for 2022 and 2023 by digitizing case data from Nepal's Ministry of Health and Population and 2021 census data from the National Statistics Office. The incidence and peak incidence months for each year were mapped, and spatial clusters (hotspots and cold spots) and outliers of incidence rates were identified using Local Moran's I. In 2022, district-wise peak cases occurred from August to October. One hotspot (high-high cluster), with high values surrounded by high-value neighbors, including six dist
