Families outside Nashville are sharing accounts of loved ones battling histoplasmosis, a rare fungal illness, as Tennessee health officials investigate an outbreak impacting over 30 people, with at least one confirmed death. These personal stories highlight the challenges in diagnosis and treatment, with many families emphasizing the importance of specific testing and advocating for comprehensive care. The Centers for Disease Control and Prevention indicates histoplasmosis, often found in soil, can lead to serious health complications and is frequently misdiagnosed. State health officials have yet to identify a definitive source for the outbreak but advise caution in activities involving soil and potential exposure to bird or bat droppings.

New research predicts a significant expansion of Aspergillus fungi, responsible for the life-threatening aspergillosis, into new regions due to climate change. This expansion, modeled using computer simulations, will affect North America, Europe, China, and Russia, increasing the risk of infection for millions. The study highlights the urgent need for increased research and preparedness, given the high mortality rate of aspergillosis and the limited antifungal treatments available. Furthermore, the rising temperatures may also increase the fungi’s temperature tolerance, making infections more likely. This underscores the growing threat posed by climate change-driven increases in fungal pathogens.

Climate change research reveals that the deadly fungus *Aspergillus*, a cause of lung disease, is poised to expand its reach across Europe and beyond by 2100 due to rising temperatures. This expansion could expose millions to infection, particularly those with compromised immune systems. The fungus thrives in warm environments, and its spread is linked to increased fossil fuel use. Experts warn of significant threats to human health and food security as a result of this fungal expansion.
