Summer fun and great outdoor weather are approaching. Sunshine is uplifting to most of us after being indoors through a long and challenging winter. By taking specific precautions throughout the summer, you may lessen your chance of getting an NTM infection or experiencing a flare-up. Educating yourself on these suggestions may enable you to truly enjoy your summer and avoid infection.
Below are some excerpts that are taken from the paper Reducing Exposure to Nontuberculous Mycobacteria (NTM), by Joseph O. Falkinham, III, Ph.D. (revised June 11, 2020). Other relevant publications also are referenced.
Flush and run water in unused lines to reduce water age. Water age refers to the time water stays in pipes in houses. The average water age in household plumbing is one to three days. When water stays in your pipes for more than three days it can lead to a loss of disinfectant and may cause NTM and other waterborne germs to grow. Increased water age can occur in plumbing in unused areas of a house (e.g., in an unused bathroom or unoccupied wing of a house). The solution is simple: have someone unlikely to be at risk for NTM disease flush commodes and run water (5 minutes) in taps in unused bathrooms and seldom-used laundry tubs, half baths, and outside faucets.1
Blogger’s note: Many of us will be traveling over the summer months and it is good to remember the above statement. Rental homes may not have flushed the systems for days before your arrival. Let others who do not have NTM lung disease or sensitive immune systems flush the infrequently used faucets, outdoor faucets, gardening hoses, etc. Doing something as simple as this can save you from getting an infection or reinfection while traveling.
Don’t drink water or use ice from a refrigerator. Many refrigerators come with outside taps for chilled water and ice. Do not use them as high numbers of NTM may be collecting in the refrigerator tap water and ice. The tap water coming into the refrigerator collects in a large reservoir and the warmth of the machinery raises the temperature of the water (before cooling), so the reservoir may contain lots of NTM. Use ice trays and bottles that are filled with boiled (10 min) or 0.2 micrometer-filtered water if you want cold water.1
Blogger’s note: My refrigerator water filter was tested years ago by the lab at Virginia Tech — the mycobacterium matched what was in my recent sputum sample.
