What is scabies?
Scabies is a skin disease caused by scabies mites. Scabies mites are small bugs, they look like spiders. They burrow into the skin up to about 1 cm long. They lay eggs there.
After 3 days the eggs hatch. The new mites crawl out of the corridors. After 2 weeks they lay new eggs elsewhere in the skin. Scabies is annoying, but it is harmless. It is contagious.
What causes scabies bites?
The females of the scabies mite dig tunnels in the epidermis and lay their eggs in it. These hatch after 3 to 4 days; the bugs are adults within 18 days. The feces, secretions, eggs, and certain substances on the surface of the mite cause an allergic reaction in human skin. This reaction causes itching and other symptoms such as blisters, bumps, bumps, redness, and scaling. With a first infection, the incubation period until this reaction takes about 2 to 6 weeks. With a renewed infection the complaints come on much faster; after 1 to 4 days after infection. In that case, the itching usually comes first and the other skin symptoms later.
How do I get infected with scabies?
For an infection, there must have been skin-to-skin contact that lasted longer than 15 minutes. That is why most infections take place through sexual contact. Shaking hands or touching briefly does not run the risk of becoming infected. The scabies mite can also be transmitted when sleeping in the bed or wearing the clothes of someone who has scabies. The condition is contagious and usually also affects bed or housemates, who must then be treated at the same time.

The symptoms of scabies are often so recognizable that the (skin) doctor can make the diagnosis by eye.

- at the front of the wrists;
- on the elbows and forearms;
- at the navel;
- inside the thighs;
- in the genitals in men and in the nipples in women;
- on the buttocks.
In common scabies, the back, neck, and face are spared. In cases of profuse or hyperkeratotic scabies, the lesions extend to the whole body, including the back.

- The patient should be treated with all family members, as well as people who have shared the same bed or had sexual or prolonged physical contact with the patient, up to 40 days before the rash appears, even if does not have scabies semiology. People who have had any accidental contact with the patient (eg handshake, social embrace, etc.) do not need to be treated.
- For greater safety, bed linen, underwear, and clothing (eg socks, towels, etc.) used by the patient and his environment during the last week before treatment should be washed in a washing machine (500C for 10 ‘) or undergo dry cleaning at high temperature. Respectively, floors and furniture (chairs, armchairs, etc.) should be vacuumed to remove mite-infected household dust, especially in cases of Norwegian scabies.
- The amount of preparation required for a body application is 30 gr or ml for a medium-sized adult or for two small children.
- The patient should apply the drug in a thin layer and evenly over the entire surface of the skin, from the neck down and giving special emphasis to the hands, the folds (interdigital, axillary, gluteal, submaxillary, umbilical), as well as the underarm fingers and toes, after first cutting the nails. The application should be done the night before going to bed.
- The drug should be removed with a warm cleaning bath, after 8 hours in children and 12 hours in adults, according to the instructions of the preparation.

The application of both keratolytic agents and antipsychotic medicine should include the scalp and face (avoiding the areas around the eyes, nose, and mouth), as well as the underside of the fingers and toes. after first cutting the nails.
