What to do if you have pubic lice

Pubic lice is a contagious parasitic disease that mainly causes parasites on human pubic hair and the skin around the anus to bite nearby skin, causing itching. Although most common in the genitals, haze is overwhelmingly present. It can survive on human hair. Its body is wider than its head, and its feet are broad so it can crawl among sparse hair. What should I do if I have pubic lice? In addition to pubic hair, pubic lice can also parasitize on hair, eyelashes, beards and manes. Like other species, it uses human blood as food, so the affected parts of the haze may feel itchy from time to time.

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.

Clinical manifestations

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.

examine

There are three characteristics of this disease: itching, rash, and blue bruises. Usually no laboratory examination is required. If necessary, adult pubic lice or eggs can be found under a microscope or magnifying glass and identified.
