Environmental Risks Explained by an expert -showers, swimming, hiking
This was posted today by a noted expert in NTM regarding risks and aerosols on another NTM & Bronchiectasis site. (ntminfo.org)
For those of you asking about enjoying the outdoors, rest assured that your risk of infection from your surroundings is low because of SPACE - in open air any germs are well-diluted by huge volumes of air.
His post:
"Yes, with the fact that MAC and NTM are everywhere, the concern is that there is no safe place.
Well, the important fact to remember is space. Showering in a bathroom exposes someone to a high density of NTM aerosolized from water to air by the showerhead. Further, staying in the misty bathroom means the exposure duration is longer.
Outside, NTM mists from waterfalls and rapids are diluted by the large volume of outside air. The same holds true for a hot tub. Outside hot tubs of spas are okay because the mist from the tub or spa is diluted by the outdoor air. An indoor spa or hot tub exposes one to an NTM mist in a closed space for a long period of time.
Swimming in lakes and streams is okay as long as you don't swallow lots of water and have gastric reflux (GERD), again as the aerosols from the water are diluted by the vast volume of air.
Outside rambles are fine, as long as one doesn't find themselves in an enclosed space, like a cave or grotto by waterfalls."

That is why we like to travel with our camper - we are in total control of our environment!
The cool mist vaporizers make tiny droplets and when the water evaporates, it leaves a dust which is the precipitate of minerals that were dissolved in the water. Boiling water to create steam causes a phase change to steam, and the precipitates should be left behind. Distilled water is boiled to create steam, and the steam is cooled to phase change back to liquid water.
That makes a lot of sense.
Interesting that you raise that question. I believe I have had BE/MAI a good few years before I was diagnosed and am of the belief '"the straw that broke the camels back" was blowing dry leaves away from the house foundation in 2021. I didn't normally do that myself but it was Covid and my help couldn't come to to do it as he normally did for me.
Diagnosed with BE in 2022 after having lost 35 pounds and my PCP finally understood, after a year or so of saying SOMETHING IS WRONG WITH ME, yes there is something wrong with you. He ordered the CScan and then called me in to the office to explain the result and held my hand as he told me BE.

In the mid 80's I contracted mycoplasma pneumonia and legionella pneumonia at the same time. My PCP at the time saved my life. I believe it leaves a 'scar' and eventually one does develop the BE that may not become full blown until later years. At least I believe that is what happened for me....BE delayed until late in my life....30 years after the pneumonias and having lived life with all that we are subjected to.

The CDC came to the small GA town where i was in school. they believed the number of us in NYC who became so acutely ill were infected by contaminated water storage on the roof of the reataurant - aka legionella. It was a very long recovery for someone in their 20’s.
What is BE?
BE is shorthand for Bronchiectasis, a lung disease characterized by "stretching out" and calcification of the bronchioles, so they are unable to function properly to remove mucus from the lung.
Like Barbara (@blm1007blm1007) it is likely my bronchiectasis developed after years of repeated bronchitis and pneumonia infections that were not well-treated as well as exposure to a number of toxic environments as a kid & young adult. All of this was probably made worse by asthma that I didn't take seriously enough, leading to long-term undertreatment.
How dreadful! I have been prone to pneumonia since that event and have had lung cancer a couple of years ago. I wear masks a lot and get every vaccine i can sign up for - pneumonia, RSV, covid, flu - and counting. Interestingly i am not prone to bronchitis and virtually never cough.
Here in NYC we have the street cleaning trucks that come around with their big rotating brushes which kick up an enormous dust cloud of every awful thing imaginable. I have actually run when I have seen them coming on days I don't have a mask handy.
In 2012 I contracted Pseudomonas, I have no idea how. The Dr kept thinking I was having asthma problems. I didn't look sick for most of the time until the end. Finally after 5 Dr.s and the last being an infectious Dr he knew what it was. First question, how long have you been hoarse? I told him a year and that it felt like I was breathing through a thick web or a thick piece of cheese cloth. He knew what it was. Confirmed with sputum samples and got rid of it. By the end of the year my lungs were so damaged from the year long episode with Pseudomonas that all of the little hairy things in the lungs were either deformed and destroyed. I could no longer move mucus out of my lungs. That led to many other infections, one after another. Finally I got an airway clearance device but by that time I think I had already had so many infections and so much scarring, Bronchiectasis had arrived. If I had have found the correct Dr with the Pseudomonas sooner, I do not believe that I would have the lung issues that I have today.
