Face melting has finally moved beyond Nazis and thieving Frenchmen.
In reality, mucocutaneous leishmaniasis takes a lot longer to act (months, years or even decades), and it begins in the most offensive way possible: with insect poop. The infection is spread through a poorly mannered sand fly that bites you and then proceeds to thank you for the meal by taking a dump in the wound. So already we're starting with the kind of action that would make Hannibal Lecter crinkle his nose and say, "Jesus, man, what is wrong with you?"
Ladies and gentlemen, the tampon that destroys lives.
But that's just how the parasite gets inside you -- that's when the scene really gets nasty. The parasite starts going after mucus cavities, like your mouth and your nose. What it's doing is essentially planting TNT in all those places, preparing to blow them to hell.
The first thing you notice, a long time after the initial shit-bite, is painful ulcers in the infected places. If you're lucky, you're left disfigured for life -- if you're not, your nose collapses into your mouth and your entire face caves in like a punctured inflatable.
