Climate Change and Dengue in India: A Panel-Data Analysis, 1997–2022

Background

Dengue is among the most climate-sensitive vector-borne diseases, with transmission shaped by temperature, rainfall, and humidity that govern mosquito breeding and viral replication. India has experienced a substantial rise in dengue burden in recent decades, concurrent with climatic change. This project, titled “Panel Data Modelling for determining Climate Change impact on Dengue in India from 1997-2022”, examines how climate variability has influenced the dengue burden across Indian states.

Approach

The study uses panel-data (longitudinal, state-by-year) statistical and econometric modelling to relate dengue incidence to climatic variables across Indian states over the period 1997–2022. The analysis was carried out in R, exploiting the panel structure to account for state-level heterogeneity and temporal trends. The work was developed as part of a data-science collaboration (with Biju Soman and colleagues).
