The patient or his relatives have a history of unclean sexual behavior, or they got sick by staying in a hotel before the onset of the disease. The pathogen of this disease is an ectoparasite, the pubic lice. The body of this type of pubic lice is relatively small, shaped like a wild turtle, and it relies on its large claws to grasp the hair shaft, and then feeds on human blood. The pubic lice are grayish white before eating, and turn rusty after eating.

2 The normal human body temperature is particularly suitable for the growth of pubic lice. Under natural conditions, the average lifespan of female lice is generally 35 days. The larvae and nymphs of pubic lice make a living by sucking human blood, and can physically suck blood 4 to 5 times a day. Pubic lice generally do not leave the pubic area. Only during sexual intercourse will pubic lice leave the original host and infect a new host. Pubic lice, like other lice diseases, can spread infectious diseases such as relapsing fever and typhus.

The most important symptom is that the patient will experience severe itching, which will worsen at night. The patient's skin will have lesions, which are usually scars or scabs, or scattered dark blue bleeding spots.

There will also be dotted dark brown blood stains on the patient's underwear, which is caused by pubic lice sucking blood.
