The impact of climate change on neuroinfectious diseases.

Purpose of review: COP28 Health Day demonstrated the growing global attention to climate health. The purpose of this article is to review the impact of climate change on the emergence of neuro-infectious diseases.

Recent findings: Climate change influences meteorological shifts and extreme weather events which may have significant and complex effects on the emergence of neuroinfectious diseases. Particularly concerning is increasing vector borne, water borne and food borne diseases. Climate associated factors contribute to the high incidence of bacterial meningitis in the African Meningitis Belt, and expansion of viral and fungal meningitis in other regions. Increased risks to those living with HIV is a public health concern. The most vulnerable communities, especially in low and middle-income countries, will be particularly impacted.

Summary: The complex effects of climate change on the emergence of neuroinfectious diseases result from consequences on ecologies, populations and health systems. The growing health burden must be addressed with a multifaceted approach to establishing climate resilient healthcare systems.
