Climate Change Drives Spread of Deadly Aspergillus Fungus Across Europe

New research warns that rising temperatures could expand the fungus's range by 77% by 2100, exposing millions to severe respiratory and invasive infections.

Mycology student Jina Patton uses a microscope to examine the morphology of a tiny mushroom found during a biodiversity survey in Port Angeles, Washington, on October 17, 2024. Amateur mycologists and mushroom experts alike are stepping up efforts to identify and name the approximately 94 percent of fungi that have yet to be identified out the 2.5 million species of fungi that are thought to exist on earth.

Overview

  • A study co-authored by Norman van Rhijn projects that Aspergillus fumigatus could spread to 77% more territory by 2100, with nine million Europeans at risk of infection.
  • The fungus thrives in warm, damp environments and at human body temperature, making it particularly dangerous for immunocompromised individuals and those with respiratory conditions.
  • Global antifungal resistance is rising due to the widespread use of azole compounds in agriculture and medicine, complicating treatment options for infections.
  • Experts emphasize the urgent need for expanded fungal biodiversity research, improved diagnostics, and the development of new antifungal drugs to address the growing threat.
  • The Wellcome Trust has committed over £50 million to fungal research, as scientists warn that climate change mitigation is critical to limiting the fungus's spread.
