B85.3: Phthiriasis

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.

Pubic lice infect pubic hair around the genitals and rectum. However, hair on the chest, in the armpits and on the face can also be affected. You can become infected by pubic lice through sex. However, you can also catch them from objects of shared use, such as clothing, towels or bedding.

Pubic lice can cause bluish-gray or red spots on the stomach, buttocks and thighs.

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.
