CLIMATE CHANGE FUELS THE SPREAD OF DEADLY ASPERGILLUS FUNGUS

As climate change intensifies, the risk of fungal infections is quietly rising—led by Aspergillus, a once-contained mold now expanding into new territories. A University of Manchester study warns that warming temperatures could significantly increase the fungus’s global footprint by 2100, putting millions more at risk of aspergillosis, a severe lung infection. Aspergillus fumigatus, the most dangerous species, is becoming more drug-resistant due to widespread agricultural use of azole fungicides.

Compounding the threat, fungal diseases often mimic other respiratory illnesses, delaying diagnosis and treatment. Vulnerable populations—including those with weakened immune systems or chronic respiratory conditions—are especially at risk. Climate-linked disasters like floods and tornadoes also help spread spores across wider regions. As Aspergillus adapts to higher temperatures, formerly cooler regions such as northern China, Russia, and Canada could face increased exposure. Urgent action is needed: better surveillance, faster diagnostics, and stronger antifungal treatments are critical to meet this growing public health threat.
