According to estimates, about 1.5 billion people--about a quarter of the earth's population--are hosts to the Ascaris lumbricoides
parasitic worm. Ascaris worms can grow to be 18 inches in length, and use their host's windpipe and esophagus to migrate between the small intestine and the lungs. A single human host may support dozen of large worms, which can be contracted by contact with fecal matter, animals, or undercooked pork. Under some circumstances (the worms dislike anesthesia, for example) one or more worms may exit from the mouth (a horrifying image
), or the anus (one of the most disgusting images I have ever seen
, and not safe for work, obviously). Here, the removal of a worm is caught on video
Too disgusting to post? Almost. But 1.5 billion people have got these in their bodies right now. That's what's grosser than gross.
