Household mold linked to 1 in 4 hypersensitivity pneumonitis cases
Medical Xpress / PLOS One ^ | May 21, 2025 | Justin Jackson / Traci N. Adams et al

Investigators report that one in four hypersensitivity pneumonitis cases in their interstitial lung disease registry could be traced back to mold inside patients' homes, identifying chronic exposure to residential mold as a potential source of severe immune-mediated lung condition.

Household exposure has been associated with a range of illnesses, including asthma, chronic rhinosinusitis, and allergic bronchopulmonary mycosis. Physicians are often unable to connect residential environments with patient symptoms, in part due to limited diagnostic tools. Without clear exposure histories or validated testing methods, the role of mold in respiratory disease remains easy to miss.

In the study, researchers retrospectively examined records from patients diagnosed with hypersensitivity pneumonitis to identify those with confirmed residential mold exposure.

Medical records came from a single-center interstitial lung disease registry in Dallas, Texas, where 231 patients had been diagnosed with moderate to definite hypersensitivity pneumonitis between 2011 and 2019. Of the 231 patients, most in their early sixties, 54 had mold exposure inside their Texas residences, with 90% showing fibrotic disease and nearly 41% requiring oxygen support.

Mold resided chiefly in bathrooms, bedrooms, or central air-conditioning systems, usually after chronic pipe or roof leaks. Invasive testing supported the diagnosis in about 86% of cases.

Among 41 patients who eliminated household mold, five achieved more than 10 % gain in forced vital capacity within four months, including four with fibrotic disease, and none experienced significant decline.

Of those who eliminated mold exposure, 12.2% experienced marked improvement in lung capacity within months, including patients with fibrotic disease, traditionally thought less responsive to intervention. No patients worsened following exposure removal. Transplant-free survival reached a median of 97.7 months—comparable to patients exposed to avian antigens or mold outside the home.

Researchers urge clinicians to expand exposure histories and consider environmental assessments in patients with compatible imaging or respiratory symptoms.

Household mold may be the cause of a condition often thought to be viral.

I was working for Toll Brothers over twenty years ago when the ‘’Radon’’ scare was big. Just more hype.

There’s more germs in your dirty laundry hamper than certain molds.

I think central air conditioning causes a lot of problems - people don’t always know what’s going on in those ducts.

Old fashioned radiators were a lot healthier.

We live in one of the moldiest places in the country. It makes everything look like crap and it can be a real pain to clean up if you don’t soak it with bleach first... but the vast majority of varieties are not very dangerous to most people.

Of course I always hate it when I put cheese in or on a meal without realizing that there was mold on it. And it screws up how the meal tastes.

You have to be pretty poor to not fix leaks.

How about house wrap that helps keep out drafts?

Not once is any name given for the mold. Which molds? With every breath you take, you inhale over 5,000 mold spores. The most prevalent fungal spores are Cladosporium, Penicillium,Aspergillus, and Fuasarium, all of which are common indoors. Relax, if your immune system is ok, few if any of those spoers will cause a problem.

Mold can just be cut off of cheese, if you bother to pay attention.

And eating mold doesn’t cause the problems that breathing certain molds can cause.

One thing I’ve noticed about bathrooms: if there’s a window in the bathroom, even if it is never opened but light comes through, there isn’t much mold.

But bathrooms with no windows usually do get mold.

I’m in Southern interior Alabama. There’s no way I’m giving up my air conditioning, even if I cough and hack half to death all summer long.

I’m not saying it’s right for everyone; I know that some regions really need central air conditioning.

But I spent the first 34 years of my life with nothing but radiators for Winter, and plenty of cross ventilation with a fan in a window here and there in the Summer.

When I moved out of there into places with HVAC, I developed all kinds of sinus and allergy crap that I’ve never gotten over.

Not every modern invention is right for every place where it’s employed.

My wife is obsessed with mold, unfortunately. You would not believe what some of the “experts” she follows on the internet say. It is like a “mold cult.” Very frustrating.

The bottom line is that mold as ubiquitous. To prevent it being a problem, all you have to do is keep your residence clean and not allow any prolonged water leaks. It really is that simple.

Yeah but boy you had to be careful around those suckers when they were hot. And how about window weights?

I had one or two of those things crunch my foot.

Mold can just be cut off of cheese, if you bother to pay attention.

And therein lies the problem... sometimes you just don't notice that the cheese has mold on it until you have already added to your burger, sandwich, or other creation. I was taught to trim mold off of cheese when I was a youngster. But my family was on a limited budget, so we usually had Velveeta. When I was a kid Velveeta could last for years, hardly ever got moldy and did not even need to be kept in the refrigerator as long as you stored it correctly. This was because of the way that it used to be processed. They have changed it in more recent times. It doesn't last as long and it can definitely mold. I don't know why... planned obsolescence?

When I was a kid, if we threw out a block of cheddar because it had a little mold on it... my dad would have taken us behind the woodshed. He would even get made if we shaved the too much good cheese off to clean it off.

Some cheeses mold quickly, and others do not, and some cheeses have mold that doesn't mess up the flavor. Some foods are meant to be moldy — and it's safe to eat them; blue cheese's taste and appearance come from a mold related to the strain used to make penicillin. But they are kind of disgusting; they stain things, and help cause things to rot... Most of them completely destroy the taste of many foods. And others like the mold growing on fruits, vegetables, bread and peanut butter can definitely make you sick.

Most molds are microscopic funguses like tiny mushrooms which are also a fungus, or athlete's foot which is also a fungus. Personally, I have never been fond of mushrooms because I know what they are and it just kind of grosses me out.

Mushrooms are very good for you; high in nucleic acids.

I agree, and I do not usually bother to pick them off of Pizzas or out of salads even though they are not appealing to me. But by nature, and the way that mushrooms are usually prepared they are slimy and disgusting. Many bugs and bug parts are actually healthy to eat; I don't choose to eat them either.
