Abstract: Dengue hemorrhagic fever (DHF) represents an escalating public health crisis in central India, with temporal transmission patterns critically influenced by seasonal environmental variation and Aedes vector dynamics. This study employed spatio-temporal GIS analysis and statistical modeling to characterize dengue transmission seasonality in Betul District, Madhya Pradesh, and establish quantitative relationships between environmental drivers and case incidence. Comprehensive temporal mapping across 12 months identified three distinct seasonal phases: high-transmission monsoon period (June-September, 68.2% of annual cases), moderate-transmission post-monsoon period (October-November), and suppressed transmission during summer and winter. Entomological surveillance revealed Breteau Index values ranging 7.92-14.35 across seasons, with strong positive correlations to dengue incidence (r = 0.89, p < 0.01). Environmental analysis demonstrated optimal dengue transmission conditions at 27-32°C ambient temperature combined with 60-78% relative humidity during heavy rainfall periods. GIS-generated temporal risk maps successfully predicted outbreak timing with 78% accuracy, enabling anticipatory vector control planning and seasonal health service resource allocation in resource-limited endemic regions.
