It can occur anywhere on the body. Pediculosis pubis is found primarily in pubic hairs but also may extend to the eyebrows, eyelashes and underarms. Pubic lice is spread through sexual intercourse or by contact with clothing, bed sheets, or towels harboring lice. When lice bite, they inject a toxin that causes irritation and a small red spot. Repeated bites can cause inflammation and a rash may appear in severe cases.
Bites can cause severe itching.
Pediculosis can be treated successfully. Your doctor can prescribe a lotion for you to use to kill the lice and nits. If left untreated, you can develop infections from scratching. It can also cause your skin to change color and become scaly and scarred. Avoid contact with a person infected with lice.
