Scientists at the University of Manchester have conducted a study that suggests climate change will allow certain Aspergillus species, a group of fungi causing aspergillosis, to spread further across North America, Europe, China, and Russia. The research, currently under peer review, comes as fungal infections pose a growing threat to public health.
Fungal infections, estimated to kill around 2.5 million people annually, are becoming increasingly resistant to antifungal medications. Climate change is expected to allow Aspergillus species to thrive in new regions, with some predicted to shift towards the Arctic and expand their range by up to 77.5%.
The study found that Aspergillus flavus could expand its range by 16% under high fossil fuel use scenarios, while Aspergillus fumigatus is predicted to increase its potential range in Europe by 77.5%. This may expose an additional 9 million Europeans to the risk of infection.
While some regions may become too hot for certain fungi, others may be exposed to increased heat and humidity due to climate change, making them more susceptible to infection. Extreme weather events can also spread spores over long distances, posing a significant threat to public health.
The research highlights the need for further study on fungal diseases and their impact on human health in the face of climate change.
