Thanks to modern medicine many diseases of the past, such as smallpox and plague, are gradually disappearing, but skin parasites in humans does not want to give up their positions even under the onslaught of the modern pleasures available to us civilization.
Types of skin parasites in humans
Scientific parasites are called all organisms that get their power at the expense of members of other species, and thus prevent its viability. People, like many other living beings who live on earth, not escape the fate of being "forced provider" representatives of this class.
Unwanted guests can hit all the organs and systems, but most often in Europe people face the representatives of the worms, which are mainly striking in the gastrointestinal tract, and skin parasites. The latter, although called skin, really can only live on the surface of the human body, but also to penetrate the skin. They usually carry lice, that cause diseases, such as lice, fleas and mites. The most common is the species of mites causing scabies.
Lice — small insects that eat human blood. They have several varieties:
- The head lice.
- The pubic bone.
Firstly, as the name implies, live on the scalp. The skin here is relatively thin, so the insects can easily bite and suck blood. Females lay eggs at one time more than hundreds of eggs — comb, which is covered with a protective sheath and firmly attached to the hair. 7-15 days, depending on how favorable the temperature, the eggs hatch, the larvae can absorb the blood after a couple of hours.
Head lice live and increases the folds of underwear and clothing, passing through the skin in just a short time to exercise. The parasite stops hair pubic part of, the genitals, the armpits and sometimes eyebrows. They are well camouflaged, so they can be found far not at once.
The lice themselves are dangerous to humans only if their number reaches several thousand, but they can be carriers of serious infectious diseases, like typhoid, or cause allergic reactions, purulent dermatitis, abscesses.
Itch mites — more unpleasant representative of the parasite. This is a microscopic arthropod settles under the skin deep layers, and feeds the people the epithelium. The mite lays eggs under the skin moves, causing intolerable itching.
Ways of infection, symptoms, prevention, treatment
Lice and scabies mites are transmitted from an infected person healthy. This happens both directly in close contact with, and through various objects: combs, towels, clothing, etc., it is often possible to hear opinion that the lice and scabies — a disease of malfunctioning members of society. This is a completely invalid statement. You can get infected and public transportation, swimming pool, the stations, camps.
Of course, the main reason is that the failure to comply with health regulations, but sometimes there are situations when a person simply does not have opportunities for regular washing, wash, change clothes. Therefore, the skin parasites are affected by several seasonal employees and construction workers live in poorly adapted premises, refugees, prisoners, the lonely, the sick people, which is difficult to treat itself.
Among the signs of parasites, the most important are intense itching, biting, scratching, pustular sores. These symptoms require careful study. On examination, the patient lice on the skin found live insects, and the hair — nits, resemble small drops of glue. Scabies mainly affects the folds between the fingers, the elbow, chest, stomach. On the skin are very visible itch moves, bubbles-papules, place the scratching covered with crusts, and the itching can be so severe that a person can sleep.
If you suspect mange, you should immediately contact your dermatologist and undergo a full prescribed course of treatment. Lice also requires a responsible attitude. Pharmacies find enough modern tools, which help to destroy the lice, but without a thorough mechanical processing (combing the dead lice and nits) is the risk of a return of the problem. If the person you find lice or parasites under the skin, you need to do thorough sanitation of the premises and things, boil underwear and bed linen, well-ironed it with a hot iron on both sides.
The best way of prevention is personal hygiene and avoid contact with carriers of disease, do not use other people's pins and other personal belongings.
