It's known to be pretty difficult to treat a lot of fungal infections in the CNS. The agents we have are pretty nasty, with severe side effects.
I'm a hacker not a doctor but I've done some research into water purification, and here is what I've learned: The body is mostly water. The task of removing microorganisms and fungus from water has been well studied. Science knows of effective agents which are proven to purify water of micro-organisms like bacteria and also fungus. Some of these are being utilized in public water decontamination, and others while als…
Let me rephrase this argument as: "The body is mostly water. The task of removing HIV from water has been well studied. Therefore it's easy to remove HIV from the body".
Just to be clear: I have no medical expertise, this is mere conjecture. But fungal infections could perhaps persist in various cells. In neurons. In spoor form. In all sorts of manifestations, where they wouldn't be affected by the same treatment that disinfects water. I don't have any expertise to say one way or the other, but I suspect that if there were a simple solution such as "just treat with Iodine, it'll kill the fungus", this discussion wouldn't be taking place.
