Climate Change Expected to Expand Deadly Aspergillus Fungus Across Northern Hemisphere

A recent study from the University of Manchester warns that rising global temperatures due to climate change are enabling the spread of dangerous fungi, particularly Aspergillus species, into new regions such as North America, Europe, China, and Russia. Aspergillus fumigatus, which thrives in temperate climates, could expand its range by up to 77% in Europe by 2100, potentially exposing up to nine million additional people to aspergillosis, a life-threatening lung infection with a high mortality rate. Meanwhile, Aspergillus flavus, which prefers hotter conditions and is resistant to many antifungal treatments, may increase its spread by 16%, threatening human health and food security by contaminating crops with harmful toxins. Experts highlight that fungal infections have been historically under-recognized despite their severity and that there is a significant lack of data on fungal pathogen presence and infection rates. Warmer temperatures create more hospitable environments for these fungi, raising concerns about preparedness and the need for better public health responses. The growing threat of fungal pathogens underscores the importance of addressing climate change and improving research and monitoring efforts.
