89 doctors.
That is how many RFK Jr. says his son saw before getting properly diagnosed after mold exposure.

He has now spoken publicly about living in a mold-infested home, the impact he says it had on nearly his entire
family, and a problem he believes needs far more attention:

“We’re not getting the information to doctors about this.”

For anyone who has spent months or years going from appointment to appointment without getting the right help, that message hits differently.

What also feels significant is where this conversation is happening now.

Mold exposure is moving beyond patient communities and specialized clinics and onto the national health stage, with the U.S. Health Secretary speaking about it from personal experience.

One family’s story does not settle the science. More national attention, however, can bring more research, better medical education, greater awareness and more patients getting the right help sooner.

89 doctors should never be the path to getting answers.

The things you use every day are often the ones you stop thinking about.

They become part of the routine, so familiar that you rarely stop to ask what might be happening in the places you cannot immediately see.

When it comes to mold prevention, the overlooked details matter.
We rounded up 10 everyday things worth paying a little more attention to.

Finding mold does not automatically mean everything you own has to go.

Some materials can often be cleaned and saved. Others are much harder to remediate once mold has grown beneath the surface. The difference often comes down to how porous the material is, how contaminated it is, and whether it can be thoroughly cleaned and completely dried.

Knowing what to keep is one part of the equation. Reducing the conditions that allowed mold to grow in the first place matters just as much.

Why can two people live in the same moldy home, yet have completely different experiences?

Research in the mold-illness field estimates that around 1 in 4 people carry certain HLA patterns associated with greater susceptibility to illness following exposure to water-damaged buildings.

For some, that susceptibility may be one piece of why mold exposure is followed by persistent, multisystem symptoms, while someone sharing the same environment may feel relatively unaffected.

Same exposure. Different genetics. Different response.

🧩 Why can two people share the same moldy environment and have completely different experiences?
One possible piece of the puzzle is HLA genetics.

HLA genes play a central role in antigen presentation, essentially helping your adaptive immune system recognize pieces of foreign material and coordinate an appropriate response.

They are also extraordinarily diverse, meaning your HLA profile can differ significantly from someone else’s.

In the mold-illness literature, certain HLA-DR/DQ patterns have been proposed as being associated with greater susceptibility following exposure to water-damaged buildings. You may have heard this described as the “1 in 4” statistic.

A negative mold allergy test can be reassuring. It can also be answering a much narrower question than you think.

Mold allergy testing looks for an IgE-mediated allergic response to specific molds. It does not tell you everything about how your body may be responding to a damp or water-damaged environment.

For some people, the picture can be more complex. Certain HLA gene patterns have been associated with susceptibility to mold-related illness, where symptoms may extend beyond the classic sneezing, congestion and itchy eyes of an allergy.

Think brain fog, persistent fatigue, headaches, digestive issues, joint pain and sleep disruption.

The important distinction is this:
Mold allergy asks: “Am I allergic?”
Mold-related illness asks a much broader question: “Could this environment be affecting my health?”

Same exposure. Different biology. Different questions. Different investigation.

A brand-new home can still have a moisture problem.

During construction, lumber and other building materials can be exposed to rain or installed before they are fully dry. Concrete also releases moisture as it cures, and once a tightly sealed, energy-efficient home is finished, excess moisture can become trapped in areas you cannot easily see.

That means mold does not need an old, neglected house. It needs the right moisture conditions, and those can exist before anyone even moves in.

A new home can look spotless and still be worth investigating if there are musty odors, signs of moisture, or unexplained issues that seem to change when you are away.
