scary fact

There is a parasite called Dracun culiasis, or more commonly "Guinea worm" that can enter your leg through drinking infected water. You won't notice anything until ~1 year later, when a small portion breaks the skin to release larvae. At this point, it's a meter long.

A. Meter. Long.

And it has to be extracted centimeter by disgusting centimeter.

NTDs are the stuff of nightmares.
