[[File:Sites of scabies.png|thumb|250п|right|Commonly involved sites of rashes of scabies<ref name=cdc/>]]
The characteristic symptoms of a scabies infection include intense [[pruritus|itching]] and superficial burrows.<ref name=Ray2009 /> Because the host develops the symptoms as a reaction to the mites' presence over time, typically a delay of four to six weeks occurs between the onset of infestation and the onset of itching. Similarly, symptoms often persist for one to several weeks after successful eradication of the mites. As noted, those re-exposed to scabies after successful treatment may exhibit symptoms of the new infestation in a much shorter period—as little as one to four days.<ref name=Markell9 />

=== Svrab ===
In the classic scenario, the itch is made worse by warmth, and is usually experienced as being worse at night, possibly because distractions are fewer.<ref name=Ray2009 /> As a symptom, it is less common in the elderly.<ref name=Ray2009/>

=== Osip ===
The superficial burrows of scabies usually occur in the area of the finger webs, feet, ventral wrists, elbows, back, buttocks, and external genitals.<ref name=Ray2009/> Except in infants and the immunosuppressed, infection generally does not occur in the skin of the face or scalp. The burrows are created by excavation of the adult mite in the [[epidermis (skin)|epidermis]].<ref name=Ray2009/> [[Acropustulosis]], or blisters and pustules on the palms and soles of the feet, are characteristic symptoms of scabies in infants.<ref name="DermNet"/>

</gallery>

In most people, the trails of the burrowing mites are linear or S-shaped tracks in the skin often accompanied by rows of small, pimple-like mosquito or insect bites. These signs are often found in crevices of the body, such as on the webs of fingers and toes, around the genital area, in stomach folds of the skin, and under the breasts of women.<ref name=DermNet>{{cite web |url=http://www.dermnetnz.org/arthropods/pdf/scabies-dermnetnz.pdf |title=Scabies |work=DermNet NZ |url-status=dead |archive-url=https://web.archive.org/web/20090327120135/http://www.dermnetnz.org/arthropods/pdf/scabies-dermnetnz.pdf |archive-date=2009-03-27 }}</ref>

Symptoms typically appear two to six weeks after infestation for individuals never before exposed to scabies. For those having been previously exposed, the symptoms can appear within several days after infestation. However, symptoms may appear after several months or years.<ref name=Bouvresse-2010 />

The most common symptoms are severe itchiness and a pimple-like rash.[2] Occasionally, tiny burrows may appear on the skin.[2] In a first-ever infection, the infected person will usually develop symptoms within two to six weeks.[2] During a second infection, symptoms may begin within 24 hours.[2] These symptoms can be present across most of the body or just certain areas such as the wrists, between fingers, or along the waistline.[2] The head may be affected, but this is typically only in young children.[2] The itch is often worse at night.[2] Scratching may cause skin breakdown and an additional bacterial infection in the skin.[2]

Uvećani snimak šugarca (Sarcoptes scabiei)

Scabies is caused by infection with the female mite Sarcoptes scabiei var. hominis, an ectoparasite.[3] The mites burrow into the skin to live and deposit eggs.[3] The symptoms of scabies are due to an allergic reaction to the mites.[2] Often, only between 10 and 15 mites are involved in an infection.[2] Scabies is most often spread during a relatively long period of direct skin contact with an infected person (at least 10 minutes) such as that which may occur during sex or living together.[3][10] Spread of the disease may occur even if the person has not developed symptoms yet.[11] Crowded living conditions, such as those found in child-care facilities, group homes, and prisons, increase the risk of spread.[3] Areas with a lack of access to water also have higher rates of disease.[4] Crusted scabies is a more severe form of the disease.[3] It typically only occurs in those with a poor immune system and people may have millions of mites, making them much more contagious.[3] In these cases, spread of infection may occur during brief contact or by contaminated objects.[3] The mite is very small and usually not directly visible.[3] Diagnosis is based on the signs and symptoms.[5]

A number of medications are available to treat those infected, including permethrin, crotamiton, and lindane creams and ivermectin.[7] Sexual contacts within the last month and people who live in the same house should also be treated at the same time.[11] Bedding and clothing used in the last three days should be washed in hot water and dried in a hot dryer.[11] As the mite does not live for more than three days away from human skin, more washing is not needed.[11] Symptoms may continue for two to four weeks following treatment.[11] If after this time symptoms continue, retreatment may be needed.[11]

Scabies is one of the three most common skin disorders in children, along with ringworm and bacterial skin infections.[12] As of 2015, it affects about 204 million people (2.8% of the world population).[8] It is equally common in both sexes.[13] The young and the old are more commonly affected.[5] It also occurs more commonly in the developing world and tropical climates.[5] The word scabies is from лат. scabere, 'to scratch'.[9] Other animals do not spread human scabies.[3] Infection in other animals is typically caused by slightly different but related mites and is known as sarcoptic mange.[14]

Znaci i simptomi

Commonly involved sites of rashes of scabies[15]

The characteristic symptoms of a scabies infection include intense itching and superficial burrows.[16] Because the host develops the symptoms as a reaction to the mites' presence over time, typically a delay of four to six weeks occurs between the onset of infestation and the onset of itching. Similarly, symptoms often persist for one to several weeks after successful eradication of the mites. As noted, those re-exposed to scabies after successful treatment may exhibit symptoms of the new infestation in a much shorter period—as little as one to four days.[17]

Svrab

In the classic scenario, the itch is made worse by warmth, and is usually experienced as being worse at night, possibly because distractions are fewer.[16] As a symptom, it is less common in the elderly.[16]

Osip

The superficial burrows of scabies usually occur in the area of the finger webs, feet, ventral wrists, elbows, back, buttocks, and external genitals.[16] Except in infants and the immunosuppressed, infection generally does not occur in the skin of the face or scalp. The burrows are created by excavation of the adult mite in the epidermis.[16] Acropustulosis, or blisters and pustules on the palms and soles of the feet, are characteristic symptoms of scabies in infants.[18]

In most people, the trails of the burrowing mites are linear or S-shaped tracks in the skin often accompanied by rows of small, pimple-like mosquito or insect bites. These signs are often found in crevices of the body, such as on the webs of fingers and toes, around the genital area, in stomach folds of the skin, and under the breasts of women.[18]

Symptoms typically appear two to six weeks after infestation for individuals never before exposed to scabies. For those having been previously exposed, the symptoms can appear within several days after infestation. However, symptoms may appear after several months or years.[19]
