Climate change increases tuberculosis risk in India

Recent studies highlight the indirect links between climate change and tuberculosis (TB), particularly affecting vulnerable populations in developing countries. Experts emphasize that climate-sensitive factors like undernutrition and air pollution are increasing TB risks. In October 2024, the World Health Organization (WHO) initiated a research framework to explore these connections, focusing on migration, food security, and health system disruptions. Current research indicates that climate change may worsen food insecurity, leading to higher TB incidence. Modelling studies suggest that rising temperatures and extreme weather events could significantly impact TB rates. The WHO and other researchers are calling for more attention to this emerging field, as TB remains a major health issue, especially in India, which accounts for a quarter of global cases.
