Additionally, the spread of A. flavus could rise by 16%, putting an extra 1 million people in Europe at risk of infection.

Fungi are highly adaptable organisms capable of colonizing new environments, with warming temperatures contributing to the emergence of pathogens like Candida auris.

Among the fungi of concern is Aspergillus, a mold that thrives in warm, damp climates and is already present globally, including in the United States, impacting humans, animals, and plants.

Despite their potential threat, fungal pathogens remain under-researched compared to viruses and parasites, with less than 10% of an estimated 3.8 million species described, underscoring the need for greater awareness and intervention strategies.

The study specifically mapped the future spread of three harmful fungi: Aspergillus flavus, Aspergillus fumigatus, and Aspergillus niger, under various climate scenarios projected through 2100.

Researchers from the University of Manchester have found that climate change is significantly increasing the risk of fungal infections, potentially affecting millions more people.

According to the CDC, fungal spores can be inhaled and lead to infections, particularly endangering vulnerable populations with weakened immune systems or existing lung diseases.

Researchers warn that within the next 15 years, significant spread of certain fungal pathogens is expected in Europe due to current emissions projections.

The rise of antifungal resistance, linked to fungicide use in agriculture, along with limited treatment options for infections, raises significant concerns about managing fungal threats.

Lead author Norman van Rhijn noted that environmental factors such as humidity and extreme weather will drive fungal adaptation and spread.

Projections indicate that the spread of A. fumigatus could increase by 77.5%, potentially exposing 9 million people in Europe to this lung pathogen that causes life-threatening infections.
