Pubic lice are parasites that live on human hair and are commonly found in the genital area. The main transmission routes include sexual contact, direct contact, and indirect contact. Sharing a bed or having close physical contact with someone infected with pubic lice may also lead to infection. The primary symptoms include severe itching of the external genitalia and visible active lice or white lice eggs at the base of pubic hairs. Before treatment, hair in the affected areas should be shaved off and burned, contaminated clothing should be disinfected by boiling, and bed sheets and pillowcases should also be properly sanitized. Under a doctor's guidance, sulfur ointment can be applied for treatment, which typically results in recovery within about one week. Sexual partners should also receive treatment simultaneously.

Medications should only be used under medical supervision; self-medication should be avoided to prevent adverse effects. Wear loose, comfortable clothing, preferably made of cotton. Regularly change and wash bed linens and bedding, and expose them to direct sunlight.
