Pubic lice, also known as crab lice, are tiny parasitic insects that infest the coarse hair in the genital area. They are about the size of a pinhead and can cause itching and discomfort. These lice are spread primarily through close physical contact, including sexual activity, but can also be transmitted through infested clothing, bedding, or towels. Treatment for pubic lice typically involves over-the-counter or prescription topical insecticides. It's important to wash all clothing and bedding in hot water to eliminate any remaining lice or eggs. Maintaining good hygiene and avoiding sharing personal items can help prevent future infestations.
