@sueinmn I just posted an article of study that Jennifer is referring to this past week. Did you see it? It is not the first study I have read about the connection between bathrooms being the possible source of mac infection. Studies showed that the dna of the mac found in showerheads did match the dna taken from a sputem sample of the patient. We cannot totally avoid mac exposure, but we can reduce the viral load and do things to minimize the exposure. I am like you; live with common sense and do the things you are doing to stay well. I am not going to make myself crazy trying to avoid it altogether.

@sueinmn Here is one article about the mac connection to the bathroom. https://academic.oup.com/cid/article-abstract/45/3/347/359377
