As there are many frightening parasites which use mammals to include humans as their hosts, proper education of what is out there lurking in the waterways and of other creatures which humans ingest, it is better to learn before your departure prior to embarking upon your journey, and going it all the wiser and prepared, as opposed to learning of you’ve become an unwilling host and breading chamber / vessel to parasites hatching and feasting with you. The world of which horrifying nightmares are made into. And many mammals to include humans residing in third world countries live their daily lives with being human hosts to some frightening creepy tiny beasts. People have returned home to the states from adventures abroad only to discover sheer pain and bizarre physical sicknesses only to seek out professional medical help, having their flesh sliced open and having hideous parasitical worms and or larva extracted from their bulging erupting flesh. And that in some cases involved parasitic worms infesting their eyes. In this case, ignorance is bliss, until you eat an infected raw Asian crab, or drink un boiled or un treated water from a stream. Aside from the crime, it’s the knowledge of Parasites which keeps me in the United States. There are some frightening parasites’ and diseases out there, which are far more frightening than Candiru.
