Everybody knows that the world is filled with creepy, microscopic parasites.
But a new Kurzgesagt YouTube video explains how a particular group of parasites are meaner and more disgusting that you ever could have imagined..
Neglected Tropical Diseases—or NTDs—are a special group of parasites that prevail from tropical and subtropical areas of the world.
They affect more than one billion people according to the World Health Organization and mainly affect populations in poverty with inadequate sanitation.
They also happen to be devastating—feasting on baby brains, damaging intestines, and keeping victims bedridden for months.
These are truly things straight out of your nightmares.
