I suspect I probably have BE. I had recurrent bouts of bronchitis as a teenager that all but stopped in my 20’s and 30’s. It wasn’t until Covid that I had a true chest infection since then. Last December before my symptoms started I tested positive for Covid and influenza at the same time. In my mind maybe I had MAC and it was just colonized asymptomatic, then the covid flu combo caused my immune system to lose control of it?
