Climate Change Could Spread Deadly Aspergillus Fungus Worldwide

A new study using climate models warns that Aspergillus fungi, including A. fumigatus, could expand their geographic range as temperatures rise, increasing risk of invasive infections in people and mycotoxin-related crop losses. The spread is amplified by azole resistance driven by overlapping use of antifungicides in agriculture and medicine. Experts call for coordinated monitoring, better diagnostics, and stronger climate action to limit spread and mitigate health and agricultural impacts.
