Thanks to the advances of modern medicine, many diseases of the past, such as smallpox and the plague, gradually disappear, but parasites of the skin in people who do not want to assign their positions, even under the pressure of the modern benefits of civilization.
In the science of the parasites who call any agency that get the power to the representatives of another type, and annoy their viability. The man, like that of many other living beings that populate the earth, did not escape the fate of being "forced support" of the representatives of this class.
Unwanted, guests can affect any organ and system, but more often in the countries of europe the people are confronted with the representatives of the helminths, which mostly affect the digestive system, and skin parasites. The last, although the skin, in reality, they can live on the surface of the human body, but to penetrate the skin of the water. To it commonly as head lice, that cause a disease, such as lice, and different types of ticks. Is the most common type of mites, which cause severe.
Head lice are small insects that feed on human blood. Have several types:
The first, as has already become clear from the title, dwell in the scalp. The skin here is quite thin, so that the insects can easily bite and suck blood. Females lay once more of a hundred of eggs (nits, which are covered with the protective sheath and firmly attach to the hair shaft. 7-15 days, depending on how favorable the temperature, the eggs hatch the larvae, capable of sucking the blood after a couple of hours.
Bar of lice live and multiply in the folds of the clothes inside the clothes, going to the skin for a while to the application of the power. The parasites affect the scalp, the pubic part, the genitals, the armpit of the cavities, and sometimes even the eyebrows. They are well hidden, so that you can find not at once.
By themselves, head lice are dangerous to humans, just in case their number rises to several thousands, but can be a vector for serious infectious diseases, as typhoid fever, or give rise to allergic reactions, purulent rashes, furunculosis.
The itchy, tick — even more unpleasant, the representative of the parasites. Microscopic arthropods was installed under the skin in its deep layers, and feeds the men of the epithelium. The tick paves beneath the skin moves, causing unbearable itching.
And the louse of the head and mangy out the tick-transmitted from an infected person to a healthy one. This occurs as with the direct support of a close contact, and through various objects: combs, towels, clothing, etc., Very often you can hear the opinion that the lice and scabies, a disease of underprivileged of the society. It is completely wrong affirmation. People may become infected, and on public transport, in the pool, in the train stations, in camps.
Naturally, the main cause is the breach of hygiene rules, but sometimes situations occur, when the man simply does not have the capacity for regular washing, washing, change of underwear. Therefore, parasites of the skin often come as a surprise to the seasonal workers and the builders, who live in poorly adapted premises, refugees, prisoners, unwed, sick people, which is difficult to take care of.
Among the signs that indicate the presence of parasites, the main ones are itching, human bite marks, scratch, pustular wounds. These symptoms require a careful inspection. The examination of the patient the piojosom in the skin are detected live insects, and in the hair — nits, which are reminiscent of small drops of glue. Scabies mostly affects the creases between the fingers, elbow folds, the breasts, the belly. In the skin look rather mangy out movements, bubbles-papules, area scratch covers lesions become scabs, and the itching can be so strong that the person can't sleep.
If you are suspected of serious it is necessary to immediately consult a dermatologist and pass the designated course of treatment. Lice also requires a responsible attitude. In the pharmacies you can find enough modern media that help to destroy the lice, but without a thorough machining (combing dead lice and nits) there is a risk of return problems. In the case of the man we have identified head lice or parasites under the skin, you must make a solid disinfecting the premises and of the things, boil underwear and bed linen, well ironed with a hot iron on both sides.
The best way of prevention is personal hygiene, you should also avoid contact with carriers of disease, not to use the strange pins and other personal items.
