Men infected with pubic lice can cause pubic lice disease, which can be cured, but there is a possibility of recurrence if they do not pay attention to hygiene and come into contact with pubic lice or lice eggs again. Pubic lice disease is mainly transmitted through sexual intercourse, and indirectly transmitted by bedding, clothing and hats, and other living items, mainly due to the repeated biting and sucking of blood by pubic lice, causing symptoms such as itching of the skin of the perineum. This can result in scratches and scabs on the skin, or scattered patches of blue bleeding petechiae. Pubic lice can be cured with proper treatment and sterilization of supplies, and the prognosis is generally good. If you suffer from pubic lice, you should go to a regular hospital as soon as possible for examination and treatment, disinfect your personal belongings in time, and check with your sexual partners at the same time to avoid cross-infection.
