What causes pubic lice in men?

Pubic lice is a disease that causes extreme pain to patients, so it is particularly important to find the cause and treatment of pubic lice. Generally, pubic lice are transmitted through sexual contact, direct contact, and indirect contact. Symptoms usually include itching, skin papules, and blue-gray spots. People need to start from the root to avoid the infection of pubic lice. If infected, they need to seek medical treatment in time.

1. Transmission channels

(1) Transmission through sexual contact: Sexual activity often provides an opportunity for pubic lice to find new hosts and infect new hosts, so pubic lice are often spread during sexual promiscuity.

(2) Direct contact transmission: refers to other direct contact transmissions other than sexual contact. Due to limited living conditions, crowded housing, poor hygiene conditions, sleeping in the same bed with patients with pubic lice, and close contact, the disease can also be transmitted.

(3) Indirect contact transmission: Pubic lice and lice eggs are often contaminated by shed pubic hair, underwear, towels, bed sheets, toilets, etc. Other people may be infected by contact with these contaminated items.

2. Symptoms

(1) Skin itching: Pubic lice use their beaks to penetrate the human skin to suck blood, which in turn causes bites and injections of their poisonous saliva into the skin.

The human body sucks blood and excretes feces at the same time, causing paroxysmal itching of the genital skin.

(2) Skin papules: There is local redness and small red spots with blood crusts at the site of pubic lice bites; local allergic reactions often cause raised papules. Some patients with pubic lice may also be infected by scratching, with symptoms of pus, exudate, and scabs.

(3) Blue-gray spots: Blue-gray spots of 0.2 to 2 cm in size can be seen near the affected area. They are painless and itchy, and do not fade when pressed. They can last for several months. These blue-gray spots can also be seen on the chest, abdomen, inner thigh, etc. They may be caused by blood coagulation caused by the saliva of pubic lice during bites.

Symptoms

Pubic lice are not only widespread in rural areas, but also found in many big cities. Because the rash is sometimes not obvious, and many people are not familiar with the disease, or are embarrassed to let doctors check it, it is often delayed or misdiagnosed. In fact, pubic lice will die within 1 or 2 days after leaving the human body, so it is not difficult to cure pubic lice. According to the above symptoms or after discovering its existence with a magnifying glass, the couple can shave the pubic hair with a razor at the same time, burn it, and then boil the underwear, so that it can be cured and prevent reinfection.

The main symptom of early pubic lice is itching of the perineum. Over time, papules and erythema may appear. In the early stage, most people do not pay attention to it or even do not treat it. Patients may accidentally see small black or red spots on their underwear. These are small blood spots where lice suck blood. If lice are found in the pubic area, they should be treated immediately. If pubic lice are not treated for a long time, it may lead to lice. People with a history of contact with patients with pubic lice or who often travel, swim, bathe in public baths, and people with a large number of mobile populations should pay attention to the sudden appearance of the above symptoms. Observe carefully to find lice.
