Mosquitoes, Microbes, and a Warming World: The Infectious Disease Threats Reshaping Global Health
A report from the Institut Pasteur highlights the growing threat of infectious diseases driven by climate change, antibiotic resistance, and the spread of invasive species like the tiger mosquito. It emphasizes the burden of respiratory infections and the risks posed by locally acquired tropical diseases in Europe.
Why it matters
It underscores the urgent need for global health surveillance and adaptation strategies as environmental shifts alter disease transmission patterns.
Infectious diseases kill nearly 15 million people each year, and the forces driving their spread are accelerating. A comprehensive threat assessment published by the Institut Pasteur in France paints a sobering picture of converging risks: mosquito-borne viruses pushing into new geographies, antibiotic resistance silently eroding treatment options, and a changing climate rewriting the rules of disease transmission worldwide.
The assessment, updated in August 2026, draws on the Institut Pasteur’s role as a national and global reference center for infectious disease surveillance. The Paris-based institution monitors a broad portfolio of pathogens on behalf of French health authorities and in coordination with international partners, giving its analysis unusual breadth across both emerging and endemic disease threats.
