Fungi that can eat human beings from inside out could spread as the world heats up: Study
As the world continues to grapple with the consequences of climate change, a new study has revealed a terrifying consequence that could have far-reaching implications for human health. Researchers at Manchester University have found that a common group of fungi, known as Aspergillus, could spread to new regions as the planet heats up, putting millions of people at risk of infection.
Aspergillus is a type of fungus that can cause a life-threatening disease called Aspergillosis, which affects the lungs and other parts of the body. The fungus can enter the body through the lungs, skin, or gastrointestinal tract, and once inside, it can cause severe damage and even death.
The study, published on Research Square, found that certain species of Aspergillus will reach new parts of North America, Europe, China, and Russia as the world heats up. The researchers used climate models to predict the spread of the fungus, and their findings suggest that areas that were previously unaffected by Aspergillosis will now be at risk.
According to the study, the mortality rate for Aspergillosis is between 20% and 40%, making it a serious and potentially deadly infection. The fungus is particularly dangerous for people with weakened immune systems, such as those with cancer, HIV/AIDS, or undergoing chemotherapy.
Aspergillus is a ubiquitous fungus that can be found in soil, decaying organic matter, and even in the air. It is estimated that up to 90% of people have Aspergillus spores in their lungs, but in most cases, the fungus does not cause any harm. However, for people with compromised immune systems, even a small exposure to the fungus can be deadly.
The study’s findings are particularly concerning given the increasing frequency and severity of heatwaves around the world. As temperatures rise, the conditions become more favorable for the growth and spread of fungi like Aspergillus.
“We used climate models to predict the spread of Aspergillus and found that certain species will reach new parts of North America, Europe, China, and Russia as the world heats up,” said Dr. Emma Smith, lead author of the study. “This is a serious public health concern, and we need to take immediate action to protect vulnerable populations.”
The study’s authors are calling for increased research into the causes and consequences of Aspergillosis, as well as improved diagnostic and treatment options. They are also urging policymakers to take action to mitigate the effects of climate change, which is driving the spread of the fungus.
As the world grapples with the consequences of climate change, it is essential that we prioritize public health and take action to prevent the spread of deadly diseases like Aspergillosis. The study’s findings are a stark reminder of the urgent need for action, and it is up to us to take steps to protect ourselves and our communities from the devastating effects of this deadly fungus.
