Climate change fuels spread of dangerous Aspergillus fungus

Rising temperatures and changing climate patterns are enabling the fungus Aspergillus to spread to new geographic regions and proliferate in areas where it was previously rare or absent. Aspergillus poses dual threats: it contaminates crops like wheat, corn, and nuts, causing significant agricultural losses, and it can trigger serious respiratory and systemic infections in humans, particularly in immunocompromised individuals. The geographic expansion of this fungal pathogen creates both food security risks and public health concerns that experts warn could intensify without mitigation efforts. Climate change is altering the temperature and moisture conditions that favor Aspergillus growth, making regions previously thought inhospitable to the fungus now vulnerable to infestation.
