Fungal thermal adaptation Fuels Human Pathogenic Fungal Diseases

Fungal diseases are a growing global health threat due to the increasing number of immunocompromised individuals and the emergence of drug-resistant fungal strains. Global warming has been profoundly reshaping the epidemiology of human fungal diseases, leading to a wider geographic distribution of pathogenic fungi (e.g., <em>Aspergillus</em>, <em>Cryptococcus</em>, and<em> Candida</em> species), increased virulence, and enhanced resistance to antifungal drugs. These phenomena are driven by the core mechanism whereby global warming enhances fungal thermal tolerance, equipping fungi with the ability to overcome mammalian thermal defenses, a key barrier to pathogenicity in humans. In this review, we have discussed how climate warming can exacerbate some major human fungal diseases (aspergillosis, cryptococcosis, and candidiasis) and also foster the development of drug-resistant strains. Furthermore, it examines emerging challenges and outlines strategic interventions on how to overcome them. Urgent action is needed to address the increasing threat of fungal diseases that will be caused by climate change. Such actions include enhanced surveillance, improved diagnostic tools, and novel antifungal therapies. These will be important to reduce the rising disease burden of human fungal diseases in a warming world.
