It is now considered outdated and inaccurate information about domestic infection scabies.pathogen transmission from person to person occurs in the majority of cases by direct contact with the patient's skin.More often - during sexual intercourse.Next on the degree of risk of infection followed by co-sleeping, contact games, sports and a handshake.As a result, the highest incidence of scabies
Domestic way of infection is highly unlikely due to the nature of the physiology of the scabies mite.Firstly, it requires at least half an hour to penetrate the skin.Second, without human mite does not live long: at 210C and a humidity of 40-80%, it dies within a half-day.Moreover, the higher temperature and drier the air the faster this occurs.Finally, to get scabies, it is necessary that the fertilized female mite crawled from one person to another, and ticks are active only at night.
Because scabies mite nocturnal life most characteristic symptom of the disease is nocturnal Sanchez (itching).Happy mite does not bother his master.However, at night, during the period of maximum activity of ticks begins uncontrollable itching, sometimes leading to insomnia.
since "make another" tick to a new owner before the first symptoms can take up to 4 weeks.After a while it becomes visible characteristic itch moves - slightly elevated above the skin line of whitish-gray color from 1 mm to 1 cm in length.Tick barely visible as a dark spot in the front end of a blind turn.There are cases of scabies in which the moves are not possible to detect visually.
itching and inflammation of the skin in scabies - an allergic reaction to the saliva, feces and eggs of mites.However, if the scratching joins a bacterial infection, the itch moves in place pustules develop.

when handling patient complaining of itching in the first rule is scabies.Especially if in a family or in a group is not the first call on a similar occasion.
Diagnosis is based on the results of microscopic analysis of scrapings from the affected areas.The analysis is performed in any STI clinic or dermatologist.The purpose of the diagnosis - to detect scabies mite.However, there are cases when the first time it can not be done.Then the doctor may refer the patient to a second analysis by scraping from the other site.
Scabies is treated quickly and successfully with the help of acaricides.Repeated disease is only possible in cases of recontamination (re-infestation) or undertreated patient.It is enough to just follow the instructions and a number of simple rules to get rid of the tick as soon as possible.
In the case of re-infection reaction to the mite appears already during the day, because the body is already familiar with the proteins produced by the parasite.Interestingly, after the treatment is generated immunity to scabies hampering reinfection.
