What type of pediculosis refers specifically to an infestation of the scalp with lice?

Pediculosis capitis specifically refers to an infestation of the scalp with lice. This condition is commonly known as head lice. Head lice are small, parasitic insects that live on the scalp and feed on human blood, leading to itching and irritation. The term "capitis" comes from the Latin word for head, which directly indicates the location of the infestation.

In contrast, the other terms refer to different types of lice infestations: Pediculosis corporis involves body lice, which infest clothing and can lead to secondary bacterial infections; Pediculosis pubis refers to pubic lice, which typically affect the genital area; and Pediculosis totalis is not a widely recognized form and does not refer to a specific type of lice infestation. Thus, the use of "capitis" makes it explicitly clear that the issue is with lice in the scalp region.
