Symptoms of pubic lice

Pubic lice are a type of parasite that often live in the pubic hair and anus of the human body. They will bite the skin of the body, causing itching symptoms in the patient. In addition, they can also spread some diseases, which is quite harmful to human health. Because it is an infectious disease, if you are married, you should treat the couple together, pay attention to the use of some topical medications for treatment, and pay attention to the cleanliness of the private parts.

Symptoms of pubic lice

The patient or his/her spouse has a history of unclean sexual contact, or stayed away from home before the onset of the disease. The main sites of disease are the pubic hair area and around the anus, and can also be seen in the armpit hair and chest hair areas. Common subjective symptoms are severe itching, especially at night, which is mainly limited to the pubic area, but can also affect the perianal area, lower abdomen, armpits, eyelashes and calves. The spouse or sexual partner may have similar symptoms.

Grayish-white sand-like particles (lice eggs) and slowly-moving pubic lice can be seen attached to the pubic hair. The pubic lice may half burrow into the skin and half remain outside the skin. The skin lesions are scratches and blood scabs, or scattered blue hemorrhagic ecchymoses, which are commonly seen on the inner thigh, lower abdomen and waist.

This is because when pubic lice suck blood, their saliva enters the blood and denatures the hemoglobin. After the pubic lice are killed, these blue spots may persist for several months. There are often dotted brown blood stains on the patient's underwear, which are caused by bleeding from the blood-sucking sites of pubic lice. Excessive scratching can lead to secondary folliculitis, impetigo and furunculosis bacterial infection.

Causes

This disease is an infectious disease. The patient or his/her spouse may have a history of unclean sexual contact or may have stayed away from home before the onset of the disease. The pathogen of pubic lice is an external parasite - pubic lice. Pubic lice are small, turtle-like creatures that use their large claws to grasp hair shafts.

Pubic lice feed on human blood. Before feeding, they are grayish white, and after feeding, they turn rusty. The host's body temperature is suitable for the growth of pubic lice. Under natural conditions, the average lifespan of female lice is 35 days. Both the larvae and adults of pubic lice feed on human blood, 4 to 5 times a day. Pubic lice generally do not leave the pubic hair area. They only leave their original host and infect new hosts during sexual intercourse. Pubic lice, like other lice diseases, can also spread infectious diseases such as relapsing fever and typhus.
