The species of lice that infest humans are essentially three:
- Pediculus humanus corporis (or Pediculus humanus humanus, body or clothing louse);
- Pediculus humanus capitis (head or scalp louse);
- Phthirus pubis(pubic louse, also commonly known as "crab").
Lice infestations are called "pediculosis".
it can also occur indirectly, for example, through hairs left on sheets, clothes, towels or even on the toilet seat. In addition, the pubic louse - in addition to the groin and perianal area - can also infest eyelashes and eyebrows.
The scalp louse, on the other hand, lives on the head, locating itself in the nape area and in the areas behind the ears and on the temples. This type of louse is especially common in school-age children.
The most common lice in our country are those of the scalp and pubis.
thus injecting their saliva. The saliva released by the insect bite causes small skin lesions accompanied by discomfort, irritation and above all an intense, continuous and annoying itch. This pushes the guest to scratch, thus favoring the appearance of scratching lesions. The formation of these lesions can favor the onset of bacterial superinfections which, in turn, can cause folliculitis, furunculosis and skin sores (this phenomenon occurs mainly in body lice infestations).The symptoms of pediculosis vary according to the type and location of the infestation, but itching and irritation are common to all forms of pediculosis.
Furthermore, the clothing louse can be a vector of causative agents of serious infectious diseases, such as trench fever, epidemic recurrent fever and exanthematous typhus. However, these pathologies are prevalent mostly in less developed countries where hygienic conditions are very poor.
