B85: Pediculosis and phthiriasis

B85.1: Pediculosis due to Pediculus humanus corporis

Lice are parasites that are nourished by human blood. Parasites are small creatures that, at least for periods of time, live off other creatures. In humans they can cause illnesses. You can become infected through close physical contact with lice, for example.

Body lice mainly occur in the tropics and where hygiene conditions are poor. Body lice live on textiles near the body, which they only leave to feed on blood. You mainly catch body lice from infected clothing, towels or bedding.

Body lice leave small red bite marks that look like a pinprick. Red bumps can also appear, especially on arms and legs. If the eyelashes are infected, the eye concerned can burn or itch.

Lice can cause severe itching, particularly at night. The skin can become inflamed through scratching. Then the skin can get infected by other pathogens such as bacteria or fungi.
