Pubic lice, also known as "crabs," are tiny parasitic insects that infest the coarse hair of the human genital area, including the pubic region, as well as other body hair, such as armpits, chest, and eyelashes. Pubic lice are typically spread through close physical contact, such as sexual activity, but can also be transmitted through sharing clothes, towels, or bedding with an infested person.

Symptoms of a pubic lice infestation may include intense itching in the affected areas, red or blue spots from lice bites, and the presence of small, grayish-white insects in the hair. Pubic lice feed on human blood and can survive for a limited time away from the body, making them easily transmitted through close contact or shared items.

Treatment for pubic lice infestations usually involves over-the-counter or prescription medicated lotions or shampoos that are applied to the affected areas. It is important to follow the instructions for treatment carefully and to wash or dry-clean any clothing, bedding, or towels that may have come into contact with the lice.

Prevention of pubic lice involves practicing safe and hygienic habits, such as avoiding close physical contact with infested individuals, refraining from sharing personal items, and maintaining good genital hygiene. Regular screening for sexually transmitted infections (STIs) and prompt treatment of any infestations can help prevent the spread of pubic lice and protect overall sexual health and well-being.
