Climate change alters global environmental patterns, directly influencing the epidemiological dynamics of infectious diseases in Brazil. This study is justified by the need to understand causal links between climate variables and the Brazilian epidemiological profile, supporting planning of surveillance systems and resource allocation in public health. The main objective is to analyze relationships between climate change and increased infectious diseases in Brazil, identifying implications for public health organization. The methodology is based on exploratory bibliographic research, with qualitative analysis of scientific literature, technical reports from international organizations, and national epidemiological bulletins. The results show geographic expansion of arthropod vectors to non-endemic regions, changes in seasonal transmission patterns, differentiated vulnerabilities of marginalized populations, limitations of epidemiological surveillance systems, and interactions between deforestation and emergence of zoonoses. It is concluded that Brazilian public health requires a paradigmatic transformation, transitioning from reactive models to proactive approaches based on risk anticipation, integrating climate data into epidemiological surveillance and strengthening local response capacities to ensure protection of vulnerable populations. The research contributes to debates on climate-health integration and points out paths for building resilient health systems capable of responding to adverse climate scenarios projected for coming decades.
