Scientists Warn of Deadly Fungi Spread Due to Climate Change

A new scientific study from the University of Manchester warns of the increasing threat of fungi, particularly Aspergillus, due to climate change. Fungal infections cause over 2.5 million deaths annually worldwide.

Aspergillus, a common fungus in the environment, is usually harmless to individuals with healthy immune systems. However, it can be fatal for patients with asthma, cystic fibrosis, COPD, cancer, organ transplants, or a history of Covid-19 or influenza.

According to Norman van Rhijn, a researcher at the University of Manchester, the fungus can grow and attack the body if the immune system fails to neutralize it. Mortality from aspergillosis ranges from 20% to 40%.

The study focuses on the species Aspergillus flavus and Aspergillus fumigatus. Aspergillus flavus is expected to expand to regions such as northern China, Russia, and the USA, while Aspergillus fumigatus is expected to increase its spread by 77.5% by 2100, potentially exposing 9 million people in Europe.

Researchers emphasize the need for increased preparedness and funding to address the fungal threat, as there are limited categories of antifungal drugs and increasing resistance.

Professor Justin Remais reported a 5% increase in aspergillosis cases in the USA between 2013 and 2023. Professor Elaine Bignell highlights the underestimated threat to public health and the need for better epidemiological monitoring.
