Abstract

Climate change is increasingly recognized as a significant driver of the spread and emergence of infectious diseases worldwide. This abstract explores the multifaceted relationship between climate change and infectious diseases, highlighting the various mechanisms through which climate variability and environmental changes influence disease transmission dynamics. Rising temperatures, altered precipitation patterns, and extreme weather events directly impact vector habitats, pathogen survival, and host-vector interactions, leading to shifts in the geographic distribution and seasonality of vector-borne diseases such as malaria, dengue fever, and Lyme disease. Moreover, climate change-induced disruptions to ecosystems, water resources, and agricultural systems can exacerbate food insecurity, population displacement, and socio-economic disparities, creating conditions conducive to the emergence and re-emergence of infectious diseases. The complex interplay between climate change, environmental degradation, and human activities underscores the need for interdisciplinary approaches to address the health implications of climate change and implement adaptation strategies to mitigate its impact on infectious disease transmission. Effective climate change mitigation, coupled with investments in public health infrastructure, surveillance systems, and community resilience, is essential for addressing the evolving threat of infectious diseases in a changing climate.
