A new study warns that climate change is fuelling the spread of deadly fungal infections globally. Two major fungal pathogens, Aspergillus fumigatus and Aspergillus flavus, are set to expand their geographical range faster across Europe and other regions as warming continues.
According to researchers from the University of Manchester, A fumigatus could expand its range by 77% by 2100 under high-emission scenarios, potentially exposing an additional nine million people in Europe. The fungus causes aspergillosis, a severe and often fatal lung infection.
Meanwhile, A flavus is projected to spread over 16% more land globally, threatening both human health and food security, particularly in regions already vulnerable to climate stress. The fungus infects crops and produces carcinogenic aflatoxins.
Climate modelling reveals that changes in environmental factors, such as humidity and extreme weather events, will drive fungal adaptation and spread. Fungal infections are harder to treat and resistant to many existing drugs, making them a growing public health concern.
Experts warn that the spread of fungal infections may be accelerated by extreme weather events, which can disturb spores and create ideal conditions for fungal proliferation. However, some parts of Africa may become too hot for certain fungi to survive.
The study’s findings come amid growing concern that fungal infections could spark a major public health crisis in coming decades. To address these challenges, researchers are calling for increased funding for fungal disease research and better preparedness strategies.
