Researchers Warn of Fungi: Researchers warn that dangerous fungi like Aspergillus fumigatus, which can “eat you from the inside out,” are spreading to new regions—thanks to rising global temperatures and shifting climate patterns. These fungi, which can cause serious respiratory diseases, are moving into parts of the U.S., Europe, and Asia where they previously couldn’t survive. And now, public health experts say we need to pay attention before it’s too late.
This isn’t science fiction. It’s happening now. And while most healthy folks aren’t in immediate danger, vulnerable people—like those with weakened immune systems or lung conditions—could be at serious risk.

The warning about fungi that can “eat you from the inside out” isn’t clickbait. It’s a real and growing public health issue driven by climate change, global travel, and environmental disruption. But with awareness, protective habits, and continued research, we can stay ahead of these stealthy pathogens.
Whether you’re a doctor, a parent, or just someone who enjoys a fall hike, now’s the time to be informed. Because the more we know about Aspergillus, the better we can fight it.
What Are These Fungi, and Why Are They Dangerous?
Let’s break it down. Aspergillus is a genus of fungi found pretty much everywhere: in dirt, leaves, air vents, compost piles, and even some foods. Usually, our immune systems squash it without a second thought. But when you’re run down, on chemo, or have a chronic condition, it can get into your lungs and wreak havoc.
Here are the main villains:
- Aspergillus fumigatus: thrives in temperate areas; responsible for most cases of invasive aspergillosis.
- Aspergillus flavus: more common in warmer climates; produces mycotoxins and resists antifungal drugs.
- Aspergillus niger: causes ear infections and sometimes lung problems; can also spoil stored food.
These fungi spread by releasing microscopic spores. You can breathe them in without realizing it. For most, that’s no big deal. But for folks with health issues? It can be life-threatening.
How Climate Change Is Helping These Fungi Spread
Here’s the deal: as global temperatures rise, the habitats suitable for Aspergillus fungi are expanding. According to researchers at the University of Manchester, by the year 2100:
- A. fumigatus‘s range could increase by 77%
- A. flavus could expand its range by 16%, reaching into Europe and Asia
That means more people will be exposed in places where these fungi were never a problem before.
“Fungi are adapting to survive higher body temperatures, making them more likely to infect humans,” notes Dr. Norman van Rhijn, co-author of the study.
Add in more storms, floods, and wildfires—which spread spores through water and smoke—and you’ve got the perfect storm for fungal expansion.
Signs and Symptoms to Watch Out For
Common Types of Aspergillosis:
- Allergic Bronchopulmonary Aspergillosis (ABPA):
- Affects people with asthma or cystic fibrosis
- Causes wheezing, coughing, and shortness of breath
- Chronic Pulmonary Aspergillosis (CPA):
- Develops over months or years
- Leads to lung cavities, coughing blood, and weight loss
- Invasive Aspergillosis (the scary one):
- Spreads rapidly from lungs to brain, heart, or kidneys
- Often fatal if not treated quickly
Symptoms of Concern:
- Persistent cough or wheezing
- Fever that doesn’t go away
- Coughing up blood
- Chest pain
- Shortness of breath
If you have a weakened immune system and develop these symptoms, get checked ASAP.
Who Is Most at Risk?
While healthy folks usually don’t have to worry, certain people are more vulnerable:
- Cancer patients undergoing chemotherapy
- Organ transplant recipients
- People with HIV/AIDS or autoimmune diseases
- Elderly adults
- People with chronic lung conditions (asthma, COPD, TB)
“Aspergillus can go from harmless to lethal depending on your health and the environment,” says Dr. Jenna Thomas, infectious disease specialist.
What Can You Do To Protect Yourself?
1. Avoid Dusty Environments
Spores love compost piles, leaf blowers, and construction sites. Wear a N95 mask if you need to be in dusty places.
2. Keep Indoor Air Clean
Use HEPA filters in your HVAC system or air purifiers to trap spores indoors.
3. Watch for Mold Indoors
Aspergillus can grow in damp corners, bathrooms, or behind walls. Keep things dry and clean.
4. Take Extra Care If You’re Immunocompromised
Avoid gardening or yard work without protection. Keep your care team in the loop if you’re feeling off.
5. Get Tested if You Feel Sick
Early detection can save your life. Blood tests, CT scans, or tissue biopsies may be used to diagnose invasive aspergillosis.

FAQs On Researchers Warn of Fungi
Q: Is aspergillosis contagious?
A: No. It can’t spread from person to person. You get it from breathing in spores from the environment.
Q: Can it be treated?
A: Yes. But treatment can be tricky due to drug-resistant strains, especially in A. flavus. Common meds include voriconazole and amphotericin B.
Q: Is this like the fungus in HBO’s The Last of Us?
A: It’s not Cordyceps, but yeah—it’s real-life fungal disease that can be deadly. And yes, it’s spreading.
Q: Should I avoid travel or seafood?
A: No need to panic. But take precautions if you’re in high-risk areas or part of a vulnerable group.
Q: Are other fungi also spreading?
A: Yes. Candida auris and Cryptococcus are two other fungal threats on WHO’s radar. But Aspergillus is especially aggressive.
Global Efforts to Combat the Threat
The World Health Organization has named Aspergillus flavus a critical fungal threat. Research is ramping up around the globe to:
- Develop new antifungal medications
- Improve early diagnostics
- Monitor environmental fungal levels
The U.S. CDC also maintains a fungal threat surveillance program and provides resources for hospitals and clinicians.
