This book delves into the complex interplay between social inequality, environmental degradation, and the rising incidence of dengue fever. Focusing on rural and urban contexts, it examines how factors such as poor housing, inadequate sanitation, water storage practices, and climate variability create breeding grounds for the Aedes mosquito and increase community vulnerability. Drawing from empirical data and comparative field studies, the book highlights how marginalized populations bear a disproportionate burden of disease due to systemic inequities and lack of access to public health resources. It underscores the need for integrated, equity-based interventions that address both the biological and social determinants of dengue outbreaks. This work serves as a critical resource for public health researchers, policymakers, and development practitioners aiming to mitigate vector-borne diseases through a multidisciplinary and inclusive lens.
