I posted this in the kidney transplant group but I am posting here also. This is something we should all be aware of.

I just read this today and wanted to alert all of the post-transplant patients to it, although I think it could benefit everyone. Apparently when you are flying and use the toilets you are better off not washing your hands at all, rather than using the airplane water! Carry sanitizer.
I knew to not drink the coffee made with the water on airplanes but it never occurred to me that the water could be so bad that even washing hands could be bad. Our last flight was coming home from Denver on JetBlue in August. Thankfully none of us had any ill effects.
