@macjane Sometimes we have to weigh the benefits over the risk. Is the pool a private outdoor pool? If so, that minimizes the bacterial load in it if it is being properly maintained. You can always have it tested by a lab for $150.00. Let me know if that is what you want to do and I will send you the lab info. I have posted links on this thread to connect you all to tests performed by NIH, who I absolutely trust; for you all to read and get the full scoop on what is found in swimming pool water. How infected are you now? Is the pool a possible place where you caught mac in the first place? I joined a gym and take a one hour cardio class (headed there in 5 mins.) I go three times a week. Getting out of the house and joining others helps a great deal with depression. Can you replace swimming for something else?
