Mysophobic

 is a quirk Wasteland 2: Director's Cut.

Description
Ever since you got measles as a child, you've been obsessed with keeping healthy. You've researched every single cure under the sun to make sure you can fight off the endless advance of disease, and keep yourself meticulously clean. You see dirt, grime, and germs everywhere you look, especially on other people. That means you're more effective at using healing items, but you're also so paranoid about others infecting you that you refuse to squander any treating your own injuries.

Illiterate
Oddly enough it appears that characters with Mysophobia are also Illiterate and are unable to read any skill books themselves. They must have skill books read aloud to them by another party member.
