I think there's a scale issue here. For such a parasite, the host body is an environment rather than prey. It's analogous to our species' depressingly poor record of considering negative externalities.
If that's the case, then you should be able to easily manage the scale of this event in your life.
By all means, demonstrate it for us!
"Around a year later, the adult worm migrates to an exit site – usually a lower limb – and induces an intensely painful blister on the skin. The blister eventually bursts to form an intensely painful open wound, from which the worm slowly crawls over several weeks. The wound remains painful throughout the worm's emergence, disabling the infected person for the three to ten weeks it takes the worm to emerge."
I have no idea what point you are trying to make or why you are being so sarcastic to me and other people you replied to.
A parasite doesn't stalk and hunt the same way a predator does prey. In this case, the larvae infect tiny fleas, which are then consumed by people and other animals drinking unfiltered water. It doesn't have a brain, as such; just a nerve ring and some sensory hairs that cue it to start eating once it is in the right environment.
I merely seek to laud your refined sense of responsibility and duty, and to express wholehearted agreement that humankind is the most vicious of creatures, unrivaled in the infliction of suffering.
Were you to provide yourself as a host to these poor and unfortunate organisms, you would doubtless attest that their impact upon you pales to insignificance compared with the misery imposed by our species.
