@jannah I am in the same boat. My family has a vacation home that is located directly across the road from a large coastal estuary. I have hiked along the estuary, kayaked in it, all before MAI diagnosis of course. Now I am not sure it is even safe for me to go and stay at the house. Of course I live in the SF Bay Area, and the bay is one huge body of brackish water (which I confess I had no sense of before my MAI diagnosis). For decades I ran along the Bay, every day, for exercise. It is certainly a question in the back of my mind as to whether that is how I picked up my MAI infection … no way to know which makes judgement calls around possible exposure sources so challenging.
