Climate change and antimicrobial resistance.

Climate change is linked to increased antimicrobial resistance (AMR), with rising temperatures and extreme weather events potentially exacerbating this global health threat.

• Why it matters: Understanding whether climate change directly causes AMR increases is crucial for developing effective public health strategies and mitigating future risks.
• What they did: The review examines ecological and epidemiological evidence, focusing on how climate-related factors like temperature and weather events may influence pathogen prevalence and antimicrobial use, involving analysis of existing studies.
• The result: Findings suggest climate change may intensify AMR by increasing infectious disease prevalence and antimicrobial demand, but further research is needed to clarify causal relationships and inform policy responses.
