My understanding is that parasite eggs can live outside the host for months if not longer (surviving long winters, etc) and can be smaller than the eye can see. They’re effectively unavoidable and that a healthy immune system keeps them in check.

I am really struggling to see any interest in the subject and very little data. From what I’ve seen doctors are fairly dismissive even when the patient brings it up (although this appears to be mostly hearsay but again to little data on what would seem to be a fascinating subject for researchers).

Anyway, thanks for your time.
