Is There a Link Between COVID & Mold Illness?
Since 2020, many people have experienced strange, lingering symptoms after COVID-19. Fatigue. Brain fog. Shortness of breath. Chest tightness. These symptoms are often labeled as “long COVID.”
But what if it’s something else?
For some people, the real issue may not be long COVID at all. It could be mold illness—also called mold toxicity—especially if they live or work in a building with hidden water damage.
In this post, we’ll explore how COVID and mold exposure may be connected—and why mold illness could be the missing piece in your recovery.
1. Mold Illness and COVID Share the Same Symptoms
One of the biggest reasons mold illness gets overlooked is because it looks a lot like long COVID. Here are symptoms they share:
- Extreme fatigue
- Brain fog
- Chest tightness or shortness of breath
- Mood swings or anxiety
- Digestive issues
- Low immune function
If you’ve had COVID and still feel unwell months later, it’s possible mold exposure is making things worse—or that mold is the root cause of your symptoms.
2. COVID Weakens the Immune System
COVID can suppress your immune system. That makes it harder for your body to fight off toxins—including mycotoxins, which are poisonous substances released by mold.
If you live in a house with mold and get COVID, your body may become less able to detox from mold toxins. This can lead to new symptoms or make existing ones worse.
3. Mold Exposure Increased During the Pandemic
During lockdowns, most people spent more time at home than ever before. Many homes were not built to handle this.
- People used more water (showers, cooking, dishes), raising humidity.
- Windows stayed closed, limiting fresh air.
- Leaks went unnoticed.
- Mold grew behind walls, under floors, and in HVAC systems.
This created a perfect storm for mold exposure—especially in homes with past water damage or poor ventilation.
4. Functional Medicine Doctors Are Noticing a Pattern
Many integrative and functional medicine clinics are seeing a rise in mold illness diagnoses—especially in people struggling with “long COVID” symptoms.
Some doctors now include mycotoxin testing and home mold evaluations in their long COVID protocols.
If traditional treatments haven’t helped you recover, it may be time to test for mold.
5. What You Can Do If You Suspect Mold Illness
If this sounds like your story, here are steps you can take:
- Test your home for mold, even if you don’t see it or smell it.
- Get a mycotoxin test to see if mold is in your body.
- Support your body’s detox pathways. This includes binders, hydration, and drainage.
And here’s something that has helped many people—including us:
Try a Parasite Cleanse
Mold and parasites often go hand in hand. Mold weakens the body, and parasites thrive in that environment. Some parasites even hold onto mold toxins, making it harder to heal.
We recommend the Parafy Parasite Cleanse from Roger’s Hood Apothecary. It’s an all-natural, filler-free herbal blend that helps detox parasites and supports recovery from mold illness. It made a huge difference in our own healing journey.
Final Thoughts
COVID and mold illness are deeply connected. For many people, long COVID symptoms may actually be caused—or worsened—by mold exposure. The good news is that mold illness is treatable, especially when caught early.
If you’re feeling stuck in your recovery, don’t ignore your environment. Sometimes, the air you breathe can hold the answers your body’s been trying to give you all along.
