While health and climate science recognize a clear linkage between infectious diseases and effects of climate change, outbreaks and disasters are frequently framed as standalone crises in public discourse. Drawing on public policy image framing literature, this paper examines effects of crossover in climate change and infectious disease discourse on policy outcomes in global infectious disease. Employing Factiva coding, I conduct a statistical analysis of infectious disease discourse and its effect on the global health policy agenda between 1990 and 2019. I find a positive relationship between climate change framing of infectious disease and global policy outcomes, significant at the 0.1 level, alongside qualitative evidence that securitized and environmental framings may have mutually reinforcing effects in elevating infectious disease on the global policy agenda.
