@pled I might be the exception in this group, but I have no issue with sitting near an outdoor pool, and even swimming in one. The contaminants (NTM, etc) are well diluted by the huge volume of outdoor air and carried away on the breeze. I have regularly been in outdoor pools, lakes and the ocean since my diagnosis and treatment almost 6 years ago, and have never gotten sick from this activity. I do stay away from hot tubs, which is sad because in cool weather we used to socialize in one regularly.
On the other hand, I avoid indoor pools completely because of the concentrated vapor in the air, and the limited air exchange. My grandkids don't like this because they love to use the Y pool in cool weather, but Dad and Mom just have to take them.
