What Is NTM?
NTM are found in nature’s water and soil. There are more than 180
species of NTM. Most do not cause disease except in people with a weak
immune system. People at risk breathe in the organisms from misty
water (for example, in a shower or hot tub) or from soil. If not treated,
many people may get a worsening lung infection.
