The CDC Is Finally Talking About Mold: Here’s What They Found
Mold Is Getting More Attention
If you've been following the mold conversation for a while, you've probably seen the headlines: the CDC is finally talking about mold.
A new CDC report, recently covered by the Associated Press, looked at invasive mold disease and what researchers are seeing in hospitals. The timing is especially relevant as flooding and extreme weather events create conditions where mold can grow in environments we frequent, including our homes.
So, what did researchers find? And what does this mean for those of us who have been asking questions about mold and health? Let's break it down.
What Did the CDC Find?
The CDC looked at potential cases of invasive mold disease across four hospitals in Atlanta between 2020 and 2024. Researchers identified 449 cases.
The lungs were the most commonly affected area, accounting for 68% of cases. Researchers also identified infections involving the sinuses, skin, central nervous system, and other areas of the body. Aspergillus was the most commonly identified mold among cases where the specific mold was known.
The report also found that many of the people affected had factors that made them more vulnerable to invasive mold disease.
For most of us, that isn't the situation we're talking about when we discuss mold in our homes, workplaces, or other everyday environments. But it does give us something important:
More research. More data. More reason to keep asking questions.
Why Flooding Matters
One of the reasons this report is getting attention is its connection to flooding.
When buildings get wet, mold can grow quickly. The CDC notes that mold can grow in homes and buildings after flooding if they aren't properly dried within 24 to 48 hours. Flooding can also increase exposure to mold and other fungi, particularly for people who may be more vulnerable.
And mold isn't always easy to spot. It can grow behind walls, underneath flooring, around HVAC systems, or in other areas affected by moisture.
Alight's education on mold in homes covers some of the places hidden mold can show up and why paying attention to your environment matters.
If you suspect mold in your home or another environment where you spend a lot of time, addressing the source of moisture is an important place to start.
What About Brain Fog and Fatigue?
This is where the conversation gets especially interesting.
Brain fog. Fatigue. Trouble concentrating. Feeling like you're running on empty even after getting a full night's sleep.
These are some of the symptoms frequently reported in the mold health space. Alight's Mold Essentials resources specifically discuss signs such as these in the context of environmental concerns.
Of course, these symptoms can have many causes. But if you're experiencing them alongside a known or suspected environmental exposure or for a prolonged amount of time, it may be worth looking at the bigger picture.
That's where Alight takes a different approach.
Education Comes First
If there's one thing we want you to take away from this new CDC report, it's this: Keep learning.
Mold is complicated, and there isn't a one-size-fits-all approach. Our goal at Alight is to provide you with the resources you need to make informed decisions about your health, without feeling overwhelmed.
Our educational resources (mycotoxin guides, blogs, and quick reference sheets) are all designed to give you a place to start. We cover topics like mold exposure, mycotoxins, gut health, PANS/PANDAS, environmental wellness, and the different systems that may be involved.
You don't need to have every answer at once. Start with what you're experiencing, learn what you can, and use that information to have a more informed approach.
Knowledge gives you a better place to start.
The Conversation Is Changing
For a long time, people navigating mold concerns have had to dig through conflicting information to find answers. Now, we're seeing more research and more attention directed toward the relationship between mold and health.
We share this because the conversation is always evolving. New research helps us better understand the many different ways mold can interact with human health, and knowledge gives you a better place to start.
Frequently Asked Questions About Mold and the New CDC Research
What did the CDC's new mold research find?
The CDC examined potential cases of invasive mold disease across four Atlanta hospitals between 2020 and 2024 and identified 449 cases. The lungs were the most commonly affected area.
Why is flooding connected to mold concerns?
Flooding can create the moisture conditions mold needs to grow. The CDC recommends taking precautions after flooding, particularly for people who may be more vulnerable to invasive mold infections.
Can mold exposure cause brain fog and fatigue?
Brain fog and fatigue are commonly discussed in the mold health space, but they can have many potential causes. If you're experiencing persistent symptoms alongside a suspected environmental exposure, consider discussing your concerns with a qualified healthcare professional.
