Purpose of Review <p>This study investigates the expanding range of mosquito-borne diseases in India, particularly in coastal regions, and explores the role of climate change in driving this trend. Coastal areas, which are densely populated and ecologically significant, are increasingly vulnerable to environmental changes such as sea level rise, increased precipitation, and higher temperatures. The review compares disease burdens between coastal and inland regions and links these patterns to changing climatic conditions.</p> Recent Findings <p>From 2014 to 2023, coastal states and union territories contributed significantly to mosquito-borne disease cases: 68.29% of chikungunya (157,783 cases), 48.52% of dengue (716,643 cases), and 49.21% of malaria (2,816,914 cases). During this period, coastal zones experienced rising temperatures and humidity, creating favourable conditions for mosquito breeding and disease transmission. These findings suggest that climate change is a key driver of increased disease susceptibility in coastal populations. Coastal ecosystems, already stressed by sea level rise and extreme weather, are becoming hotspots for mosquito proliferation, further exacerbating public health risks.</p> Summary <p>The study highlights the growing threat of mosquito-borne diseases in India’s coastal regions due to climate change. Coastal populations are disproportionately affected as environmental changes create ideal conditions for mosquito breeding and disease spread. The findings underscore the need for targeted public health interventions, including enhanced surveillance, vector control, and community awareness programs. Long-term strategies to mitigate climate change impacts on coastal ecosystems are also essential to reduce future disease risks. This review provides critical insights and recommendations for managing mosquito-borne diseases in a changing climate.</p>
