Many cases are self-treated or treated discreetly by personal physicians, which further adds to the difficulty of producing accurate statistics.It has been reported that the trend of pubic hair removal has led to the destruction of the natural habitat of the crab louse populations in some parts of the world, thereby reducing the incidence of the disease. Etymology and history
Infestation with pubic lice is also called phthiriasis or phthiriasis pubis, while infestation of eyelashes with pubic lice is called phthiriasis palpebrarum or pediculosis ciliarum. Linnaeus was first to describe and name the pubic louse in 1758, when he called it Pediculus pubis. The disease is spelled with phth, but the scientific name of the louse Pthirus pubis is spelled with pth (an etymologically incorrect spelling that was nonetheless officially adopted in 1958). Other animals
Humans are the only known hosts of this parasite, although a closely related species, Pthirus gorillae, infects gorilla populations. References
