; also sometimes known as the seven-year itch) is a contagious skin infestation by the mite Sarcoptes scabiei. The most common symptoms are severe itchiness and a pimple-like rash. In a first-ever infection, the infected person usually develops symptoms within two to six weeks. During a second infection, symptoms may begin within 24 hours. These symptoms can be present across most of the body or just certain areas such as the wrists, between fingers, or along the waistline.
As such, Open Access can be defined as an instrument ultimately used for public welfare to stimulate the growth of global science, as well as maintain the quality of scientific achievements at the same time. Scabies is one of the commonest dermatological conditions, accounting for a substantial proportion of skin disease in developing countries. Globally, it is estimated to affect more than 200 million people at any time, although further efforts are needed to assess this burden. Prevalence estimates in the recent scabies-related literature range from 0.2% to 71%. In Europe in the late 19th through mid-20th centuries, a sulfur-bearing ointment called by the medical eponym of Wilkinson's ointment was widely used for topical treatment of scabies. The contents and origins of several versions of the ointment were detailed in correspondence published in the British Medical Journal in 1945.

Areas with a lack of access to water also have higher rates of disease. It typically only occurs in those with a poor immune system and people may have millions of mites, making them much more contagious. In these cases, spread of infection may occur during brief contact or by contaminated objects. The mite is very small and at the limit of detection with the human eye. It is not readily obvious; factors that aid in detection are good lighting, magnification, and knowing what to look for.
While this treatment is necessary to kill scabies, home remedies can help control and prevent their spread.

Searches for these signs involve either scraping a suspected area, mounting the sample in potassium hydroxide and examining it under a microscope, or using dermoscopy to examine the skin directly. Scabies outbreaks have occurred among patients, visitors, and staff in institutions such as nursing homes, long-term care facilities, and hospitals. Such outbreaks frequently are the result of delayed diagnosis and treatment of crusted scabies in debilitated, immunocompromised, institutionalized, or elderly persons. The characteristic itching and rash of scabies can be absent in such persons, leading to frequent misdiagnosis and delayed or inadequate treatment and continued transmission. Scabies often is not recognized until it begins to appear among staff and other patients at the institution.
In high-income economies, cases are sporadic, yet outbreaks in health institutions and vulnerable communities contribute to significant economic cost in national health services. Human scabies is a parasitic infestation caused bySarcoptes scabiei var hominis. The microscopic mite burrows into the skin and lays eggs, eventually triggering a host immune response that leads to intense itching and rash. Treatment should involve the entire household, and any others who have had recent, prolonged contact with the infested individual. Options to control itchiness include antihistamines and prescription anti-inflammatory agents.

Clean the room of patients with crusted scabies regularly to remove contaminating skin crusts and scales, which can contain many mites. All staff and visitors should wear gloves and gowns on entering the single room or when having direct contact with patients suspected or confirmed to have scabies. All staff and visitors should wear gloves and gowns on entering the single room, or when having direct contact with patients suspected or confirmed to have scabies. Guidelines for preventing transmission vary depending on the type of scabies, the number of cases, and the degree and duration of skin exposure that a person has had to an infested person. Bedding, clothing and towels used by infested people any time during the 3 days before treatment should be machine washed and dried using the hot water and hot dryer cycles, or be dry-cleaned.
Scabies is contagious and can spread quickly in areas where people are in close physical contact. The hallmark symptoms of scabies include a rash and intense itching that gets worse at night. Continuous scratching of the infected area can create sores that become infected. If this occurs, additional treatment with antibiotics for the skin infection may be recommended.

Keratolytic cream A topical keratolytic cream may also be used to help reduce the crusting of the skin and aid in the absorption of the topical permethrin or benzyl benzoate. Benzyl benzoate 25% Benzyl benzoate may be used as an alternative topical agent to permethrin. Lower concentrations may be used in children (10% or 12.5%). Sulfur (5%-10%) ointment Sulfur in an ointment base is safe for topical use in children, including infants under 2 months of age. The odor and cosmetic quality may make it unpleasant to use . Scabies usually is spread by skin-to-skin contact with a person who has scabies.
Skin-to-skin contact with scabies patients should be avoided for at least 8 hours after treatment. In addition, an institution-wide information program should be implemented to instruct all management, medical, nursing, and support staff about scabies, the scabies mite, and how scabies is and is not spread. Epidemiologic and clinical data should be reviewed to determine the extent of the outbreak and risk factors for spread. Human scabies is caused by an infestation of the skin by the human itch mite (Sarcoptes scabiei var. hominis).
