A recent study suggests that a dangerous fungus is likely to spread into new regions of Europe, triggered by rising temperatures associated with climate change. This fungus, known as Aspergillus, poses serious health risks, potentially affecting millions annually as it moves into northern areas of Europe, and other parts of Asia and the Americas.
Norman van Rhijn, a research fellow at Manchester University, co-author of the study, expressed concerns about a tipping point for fungal pathogens that thrive in various environments, including homes. He mentioned that fungal infections could lead to millions of deaths globally each year.
One such infection is Aspergillosis, which affects the lungs and can spread to other organs in the body. Van Rhijn pointed out the significant impact this could have, stating, “We’re talking about hundreds of thousands of lives… In 50 years, where things grow and what you get infected by is going to be completely different.”
Interestingly, Aspergillus isn’t entirely harmful; it plays beneficial roles in food production, such as in the fermentation of soy sauce and sake. However, the spores can be hazardous, especially for individuals with asthma, cystic fibrosis, or other compromised immune systems.
The study indicates that Aspergillus fumigatus could expand its reach across an additional 77 percent of the area by 2100, a result of ongoing fossil fuel usage. This expansion could put around nine million people in Europe at risk. The species is adept at thriving in high temperatures, such as the 37°C (98.6°F) of the human body.
Professor Elaine Bignell from the MRC Centre for Medical Mycology at Exeter University commented on how the fungus’s natural habitat has possibly given it an edge in colonizing human lungs. Additionally, another variety, Aspergillus flavus, typically found on crops, could invade new territories in parts of northern China, Russia, Scandinavia, and Alaska by 2100, jeopardizing local ecosystems as some regions in Africa and Brazil may become inhospitable.
Darius Armstrong-James, a professor of infectious diseases at Imperial College London, emphasized the serious health and food security risks posed by these organisms.
