Pediculosis

Pediculosis is an infestation of lice that causes severe itching in humans. Constantly scratching itchy areas of the skin can lead to the development of a secondary bacterial infection.

Head lice or human head louse (pediculosis humanis var. capitis) is very common among schoolchildren. Infection with it does not necessarily indicate poor personal hygiene, as it can occur when a sick child comes into contact with a healthy one. This type of lice is relatively easy to kill using malathion or carbaryl lotions.

Body or body louse (body lice or pediculosis corporis) is more common among tramps and refugees. To combat it, the help of social services is usually required.

Infection with pubic louse (pubic lice) of the Phthirus pubis species usually occurs through sexual contact. This species is destroyed in the same way as the head louse.

Pediculosis, also known as lice infestation, is a common problem caused by insects known as lice. It can affect various parts of the body, including the head, body, and pubic hair area. Pediculosis is accompanied by intense itching, and constant scratching of the itchy areas can lead to the development of a secondary bacterial skin infection. In this article, we'll look at the three main types of lice—head, body, and pubic—and how to control them.

The head lice, or human head louse (pediculosis humanis var. capitis), is the most common type of louse. It is common among schoolchildren, and infection with it does not indicate poor personal hygiene. Head lice are spread through close contact between people, especially when sharing personal care items such as combs, hats or hair. Symptoms of a head lice infestation include severe itching on the scalp, eggs (nits) in the hair, and presence of lice. Treatment for head lice includes the use of special lotions containing malathion or carbaryl, as well as combing the hair with a special comb to remove lice and nits.

Body lice (body lice or pediculosis corporis) are commonly found in people living in poor hygienic conditions, such as tramps or refugees. Body lice are transmitted through direct contact with contaminated clothing or bedding. Clothing is an ideal environment for body lice to reproduce and survive. Symptoms of body lice include intense itching, red rashes, and possible signs of a secondary infection. Management of body lice requires a collaborative effort among social services to provide affected people with access to clean clothing, bedding, and showering.

Pubic lice infection usually occurs through sexual contact, although it can also be transmitted through direct contact with contaminated clothing or bedding. The pubic louse, known as Phthirus pubis, lives in the pubic hair area and can also affect other hairy areas such as the armpits, eyebrows and eyelashes. Symptoms of lice in the pubic area include intense itching, eggs, and lice in the pubic area. Treatment for pubic lice includes using special medications designed to kill the lice, as well as shaving or removing infested hair.

In general, to prevent head lice, it is important to maintain good personal hygiene and avoid close contact with infected people or their personal belongings. If you suspect a lice infestation, it is important to take immediate steps to treat and prevent the infection from spreading.

Lice can not only be a physical nuisance, but also cause social stigma and psychological problems, especially in children. Therefore, it is important to educate the public about the causes and prevention of head lice to ensure the health and well-being of all people.

In conclusion, head lice is a common problem caused by lice infestation. Head, body and pubic lice can cause intense itching and discomfort. However, with proper treatment and preventative measures, this condition can be successfully managed. If you suspect a lice infestation, it is recommended that you consult a medical professional for diagnosis and appropriate treatment.

Pathogenesis.

Depending on the habitat of lice, there are several types: head lice, body lice, pubic lice, etc. The most common are head lice. The main organ in a woman’s life is the eggs. They are located on the hair of the head, hanging freely from the anus. When swallowed, some of the eggs die, others move along the esophagus, are thrown out of the stomach by cilia and are swallowed back. Some of the eggs reach the intestine, where some of them die, while the other part lays eggs on the surface of the intestine. Body lice and pubic lice lay eggs primarily on the human body. Hookworms lay eggs in the soil. For hookworms and other nematodes, the soil and the irrigated vegetables used by some people, mainly spinach, are important. The main route of lice infection is direct contact, but indirect contact can also occur when they get on common objects. Normally they do not enter the body mechanically. Transmission occurs to a greater extent during sleep or after bathing. The appearance of pediculosis is facilitated by household and social conditions that contribute to its spread (unsanitary conditions, harsh climate).
