Aspergillosis, caused by a mold or fungus, can turn life-threatening, particularly for immunocompromised people. It may also impact crops, animals, and ecosystems. While most healthy people are unaffected by inhaling its spores, experts in the new research published in pre-print (not yet peer-reviewed) on Research Square, warn that a warming climate could expand its reach, causing a rise in infection rates, and strain medical systems.
The study also mentions the projected year when the fungus prevalence will grow drastically. According to researchers, the deadly infection may rise by 77% by the year 2100, exposing millions of people in Europe to the infection.
'The study indicates that some global climate change scenarios will result in changes of habitat ranges for certain lung and systemic
,' Jacob Glanville, CEO of Centivax, a San Francisco biotechnology company, told Fox News.
'Given that Aspergillus is prevalent in the environment and ongoing changes in climate favor growth of Aspergillus in the environment, it is likely that levels of human exposure will continue to increase, as will diseases of plants, crops and animals,' Cornelius Clancy, MD, associate chief of the VA Pittsburgh Health System and opportunistic pathogens at the University of Pittsburgh told Fox News Digital.
Who is at risk?
Aspergillus spores aren't a threat for healthy people, but for those who are immunocompromised.

People who are receiving chemotherapy may face a risk of the spores affecting their lungs and causing Aspergillus pneumonia or other lung infections, which can spread in the blood to other organs, according to Clancy.
'If your immune system is intact, then these spores are usually removed by immune system cells in the airways and lungs and disease does not occur," Clancy said.
But for people whose immune systems respond excessively to proteins in the spores, infection can cause reactions ranging from allergy-like symptoms to invasive disease.
'In persons who are immunosuppressed, such as those receiving cancer chemotherapy, there is a risk of spores invading the lungs and causing Aspergillus pneumonia or other lung infections, which can then spread in the blood to other organs,' Clancy cautioned.
Elderly or asthmatic
Older people or people with pre-existing respiratory diseases like asthma may be at a higher risk of complications from the fungal infection.
According to mayoclinic, some people with asthma or cystic fibrosis have an allergic reaction to aspergillus mold. Signs and symptoms of this condition, known as allergic bronchopulmonary aspergillosis, may include fever, a cough that brings up blood or plugs of mucus, and worsening asthma.
Some fungi may also become resistant to drugs over time, according to experts.
Immunosuppressed people should be the most cautious group as per experts and they must talk to their healthcare experts for protective measures.

3 'City-Killer' Asteroids Could Strike Earth In Weeks, Say Scientists
At least three large asteroids, powerful enough to destroy an entire city, could be on a collision course with Earth in the coming weeks, a new study has warned. Published in the journal Astronomy and Astrophysics, the study highlights the threat posed by three space rocks-named 2020 SB, 524522, and 2002 CL1-which currently share an orbit with Venus. According to the international research team led by Valerio Carruba from Sao Paulo State University in Brazil, these asteroids are hidden in the Sun's glare, making them nearly impossible to detect with telescopes on Earth. While their current paths don't bring them close to Venus, researchers caution that even a minor gravitational disturbance could shift their orbits toward Earth, with potentially catastrophic consequences. If one were to strike, the impact could create a crater more than 3 kilometres wide and release energy up to a million times greater than the atomic bomb dropped on Hiroshima, Fox News reported. "These co-orbital asteroids are protected from close encounters with Venus, but not with Earth," the researchers said, as quoted by The Daily Galaxy. The objects are especially dangerous because their position relative to the Sun acts like a cosmic blind spot, making last-minute detection extremely difficult. The Rubin Observatory in Chile, which monitors such threats, would have just two to four weeks' notice before any potential impact. The study suggests that only a dedicated space-based mission near Venus could effectively detect these hidden, potentially hazardous asteroids.

Climate change may fuel spread of fungi that could 'eat you from inside out'
As Covid-19 cases begin to rise again in parts of the world, including India, there's another silent but serious health threat emerging, this time from the fungal kingdom. The rising global temperatures could accelerate the fungi capable of eating you from inside out. A new climate modelling study by researchers at the University of Manchester shows that rising temperatures could dramatically alter the spread of Aspergillus, a group of airborne fungi known to cause severe respiratory infections in humans and widespread damage to crops. Published on the preprint platform Research Square, the study titled Climate change-driven geographical shifts in Aspergillus species habitat and the implications forplant and human health maps how the geographical range of three major Aspergillus species could expand significantly by year 2100, exposing millions more people to the risk of infection, especially across Europe and Asia. Why are Aspergillus fungi a growing concern? The Aspergillus genus includes several common environmental fungi found in soil, compost, and air. While generally harmless to healthy people, they can cause aspergillosis, a serious respiratory infection, in those with weakened immune systems. These fungi are also notorious for spoiling crops and producing dangerous mycotoxins. But here's the real problem — they're evolving. Rising global temperatures and widespread use of agricultural fungicides are helping these pathogens become more heat-tolerant and resistant to antifungal drugs, leaving doctors with fewer tools to treat infections. How rising temperatures increase fungal risks Using global climate models and species distribution tools, the University of Manchester team simulated how suitable habitats for Aspergillus fungi will shift under three scenarios, including low, intermediate, and high warming. Impact in a low warming scenario (below 2°C): Minimal changes in habitat range for Aspergillus species, and the spread is relatively contained. Impact in intermediate warming (2.5–3°C by 2100): Noticeable spread of fungal pathogens into new regions, especially in the Northern Hemisphere. Impact in high warming (around 4°C by 2100): Significant and rapid expansion of Aspergillus habitats, particularly A. flavus and A. fumigatus, into Europe, North Asia, and North America, putting millions at increased risk. ALSO READ | Why scientists are especially alarmed by these findings Antifungal resistance: A. flavus, in particular, is already resistant to many existing treatments. Lack of medical tools: There are no vaccines, diagnostics are limited, and antifungal options are few. Dr Norman van Rhijn, lead author of the study, explains in a statement, 'We've already seen the emergence of Candida auris due to rising temperatures, but this is just the beginning. These maps show how fungal pathogens will likely impact most areas of the world in the future. Raising awareness and developing effective interventions is essential.' Fungi are shifting toward the Northern Hemisphere According to the study, the biggest changes will happen in the Northern Hemisphere. Europe and North Asia: Projected to see the largest increase in fungal suitability due to milder climates becoming warmer. Africa and South America: Paradoxically, these regions could become too hot for fungi like A. flavus to survive — threatening ecosystems that rely on fungi to decompose organic matter and regulate the carbon cycle. The study shows a striking poleward shift: fungi are moving north, where millions more people could be exposed. Climate change threatens food security via fungal spread The study highlights that A. flavus and A. niger are major crop pathogens, especially for maize, rice, and grapes. The research warns of: Reduced habitat suitability in current crop-growing zones Increased risk of contamination in new areas Food insecurity due to loss and spoilage of yields Antifungal resistance is also being driven by overuse of fungicides in agriculture, which compromises both plant and human health. Why fungal threats are difficult to fight Unlike bacteria, fungi are biologically closer to humans, meaning antifungal drugs often have toxic side effects. Plus, only a tiny fraction of the estimated 1.5 to 3.8 million fungal species have been studied, and less than 10 per cent have been sequenced genetically. How to prepare for a warming-driven fungal threat According to the study and public health experts: Accelerate climate action to limit warming and slow fungal spread Invest in fungal diagnostics, surveillance, and treatments Improve awareness among healthcare workers and the public Develop sustainable farming practices to reduce fungicide-driven resistance Fungi may not make daily headlines like viruses do, but they are quietly becoming one of the most dangerous climate-driven health threats of our time. As global warming accelerates their spread and evolution, ignoring them is no longer an option. For more health updates, follow #HealthWithBS

What is Aspergillus? The deadly fungus spreading rapidly and can eat humans 'inside out'
An increase in global temperatures might result in the Aspergillus fungus that causes many annual deaths affecting greater areas, the new research reveals. Many types of Aspergillus spread in the world and can infect people, pets and plants, as scientists at Manchester University explain. According to both The Lancet and CNN, the study is being reviewed at present by a group of international experts. What is Aspergillus? In many parts of the globe, Aspergillus is recognised as a common group of fungi. It causes aspergillosis, which can be fatal, and primarily affect the lungs. Researchers used several types of modelling and forecasting techniques to track where Aspergillus would spread in the future. As part of the research, scientists found that there were specific Aspergillus species that will expand in the future as the climate crisis intensifies. These species will expand into new parts of Canada, the U.S., Europe, China, and Russia. In comparison, viruses and parasites have received more attention from researchers than fungi, says Norman Van Rijn, one of the authors of the study. He predicts these are expected to impact the major areas of the world. Why is this infection so deadly and who is at risk? An estimated figure is that fungal infections every year claim the lives of more than 2.5 million individuals. It's possible the number is even higher since not all data is available. As with many fungi, Aspergillus appears in soils as tiny filamentous structures. Subsequently, they create many spores that travel with the air. Every day, humans take in these air pollutants. Usually, most people do not have any issues with their health because their immune system can deal with most threats. That's different for individuals suffering from asthma, cystic fibrosis or COPD. Patients who have had cancer or organ transplants are high at risk due to weakened immune system. According to Van Rijn, if your immune system can't get rid of the spores, the fungus begins to grow. 'The fungus starts to grow and basically kind of eat you from the inside out, saying it really bluntly,' van Rijn said. Aspergillus flavus, which favours hot and tropical places, could see its range grow by 16% if we keep relying on fossil fuels, according to the study. Candida species can cause really serious infections and are still resistant to some drugs. For this reason, the infection can spread among a wide range of food crops, making it a serious problem for food security too.
