Pubic lice, an infectious parasitic infectious disease, is generally caused by sexual transmission, direct transmission, or indirect infection. For example, if one party has louse yin, it may be transmitted to other people after sexual contact, or if the patient lives in a poor environment, it can be transmitted to others by contacting some bedding, or by contacting some articles or clothes. If the patient is infected with pubic lice, it is recommended that the patient should go to a regular hospital for examination, and then treat symptomatically according to the examination results. In daily life, patients should pay attention to personal hygiene and try not to share personal belongings or towels with others.
