The health threats we face are numerous and often unpredictable. Among them, pathogenic mushrooms are generally not the first of which we think. However, recent research shows that they could become a major threat in the years to come. Indeed, the overall increase in temperatures seems to promote their proliferation. While some mushrooms are harmless, even beneficial, others have the potential to cause serious infections, both in humans and in agricultural ecosystems. This text explores the implications of this growing threat.
Pathogenic mushrooms: a silent threat
In the collective imagination, great health threats often come from viruses or natural disasters. However, pathogenic fungi, although less publicized, represent a real danger. As Norman Van Rhijn, a researcher at the University of Manchester, indicates, these organizations are often overlooked, despite their destructive potential. Fungal pathogens could affect large regions of the globe in the near future, especially due to the increase in global temperatures.
The diversity of mushrooms is immense. It is estimated that only 10% of known fungal species have been described. Among them, some are harmless and even consumed commonly, while others are able to cause serious infections. The evolution of climatic conditionssuch as extreme humidity or weather events, promotes the adaptation and spread of these fungi, thus increasing their potential impact on human health and agriculture.

Climatic scenarios and their impacts
Scientists have studied various climatic scenarios to understand how the rise in temperatures could influence the proliferation of pathogenic fungi. The results are worrying. For example, the “Aspergillus flavus”, a mold producing dangerous mycotoxins, could see its spread increase by 16% in a few years if one continues to massively use fossil energies.
In the worst case, this could expose one million additional people in Europe to these infections. These thermotolerant mushrooms Prospered in hot and humid climates, which makes them particularly resistant to climate change. In addition, other species such as the “Aspergillus fumigatus” could extend their distribution area of 77.5%, endangering 9 million additional people.

The health and ecological consequences
Infections caused by pathogenic fungi can be severe, especially in immunocompromised people. The effects on human health are therefore a major concern. However, the ecological consequences should not be overlooked. Mushrooms play a key role in the decomposition of organic matter, an essential process for the health of ecosystems.
In some regions, especially in Africa, certain crucial species for this decomposition may not survive the extreme temperatures. This loss could cause ecological imbalancesaffecting biodiversity and soil fertility. A chain reaction could then start, threatening food security and local livelihoods.

Prevention and awareness: necessary actions
Faced with these threats, prevention and awareness is essential. Developing effective interventions against fungal pathogens is crucial to reduce their potential impact. This includes finding solutions to limit the spread of these fungi, as well as strategies to protect the most vulnerable populations.
Awareness of the general public and political decision -makers is also essential to guarantee a coordinated and effective response. Without a concerted actionpathogenic fungi could become a major health and ecological threat. Researchers highlight the importance of integrating these issues into public health and ecosystem management policies.
While we continue to cope with the challenges posed by climate change, pathogenic mushrooms remind us that many threats still remain to be discovered. How are we going to adapt our societies to deal with these emerging dangers and preserve our health as well as that of our planet?
