Dengue fever, a mosquito-borne viral disease, poses a significant public health challenge in tropical and subtropical regions, with its transmission dynamics intimately linked to climate variability. This review article examines the impact of climate factors, particularly rainfall and temperature, on dengue transmission in West Bengal, India, and explores the potential for developing effective early warning systems (EWS). Drawing on a comprehensive analysis of epidemiological data and climatic records from the region, we highlight how seasonal monsoon patterns and temperature fluctuations influence Aedes mosquito populations and dengue incidence. The study underscores the urgency of integrating climate data into public health strategies to mitigate future outbreaks amid climate change. By synthesizing existing literature and presenting comparative data from multiple studies, we provide insights into the complex interactions between environmental variables and disease dynamics, offering recommendations for policy and practice to enhance preparedness in West Bengal and similar endemic areas.
