@macjane Jane, Hello. I too live in Michigan, at least in the summer (Arizona in the winter)—on a small lake in Hartland Township about 30 miles north of Ann Arbor. I was recently diagnosed with a mild case of MAC at the University of Michigan Medical Center. My infectious disease doctor told me that it is very unusual for someone in Michigan to have MAC and suspects I got it in Arizona (or Colorado, where I lived for 27 years). I’d love to know where/how you think you got MAC. Where in Michigan do you live? Do you have city or well water? (I have well water in an area of prairie fens.) Have you recently lived anywhere other than Michigan?
Thanks and good luck, Lori
