As the world deals with COVID-19, there is increasing attention to the threat of emerging and re-emerging infectious diseases. India is especially vulnerable to climate-induced health risks and a hotspot for infectious diseases. In this study we use a scoping review to synthesize evidence on the impact of climate on infectious diseases. We use this to uncover gaps and understand the implications for policymaking and health system preparedness. There is a strong evidence base linking climate change to disease outbreaks, both directly and indirectly. Socio-economic factors are the modifiers that determine disease severity in different populations and locations.
