Infestation of Humans
Infestations of crab lice are known as pediculosis pubis or phthiriasis pubis (which, unlike the generic name of the louse, is spelled with a phth). Infestation of the eyelashes is referred to as pediculosis ciliaris or phthiriasis palpebrarum.
The main symptom of infestation with crab lice is itching, usually in the pubic-hair area, resulting from hypersensitivity to louse saliva, which can become stronger over two or more weeks following initial infestation. In some infestations, a characteristic grey-blue or slate coloration appears (maculae caeruleae) at the feeding site, which may last for days.

“To not be afraid in our world is the message that doesn’t derive from reason, but maybe from this mysterious capacity given to humans which we call—not without a little embarrassment—faith.”
—Friedrich Dürrenmatt (1921–1990)
