@mtmteach, I am happy to hear that you are catching this disease in the early stages. Your dr is right, avoid ill people, and wash your hands immediately after being in public places to avoid picking up germs that cause colds and flues. AVOID hot tubs, and indoor swimming pools! They can be loaded with mac. Wish I had known that. We had a hot tub for years and were in it every night.....pretty sure that is where I got my mac infection. I wish my drs that diagnosed with bronchiectasis many years back had said "Don't get into hot tubs", but they didn't.
