What is scabies?

Readers Comments 1 Share Your Story

Human scabies is caused by the human itch mite (Sarcoptes scabiei, variation or subtype hominis). This itch mite burrows into the upper layers of skin and lays its eggs in the skin. This itch mite is found worldwide and often causes outbreaks in places where people are living close together, such as dormitories, nursing homes, institutions, or prisons. The rash often includes areas such as the web spaces of the fingers, wrists, beltline, feet, scrotum, and areolas, but other areas may get infected.

Is scabies contagious?

Scabies is contagious. However, it usually requires fairly long skin-to-skin contact with an infested person (for example, carrying a person, sleeping with the person, or sexual partners). Infrequently, it may be contagious through contact with clothing or bedding, but this form of transfer of scabies is thought to be very infrequent. In general, most people who become infested with scabies usually have about 10-15 itch mites on their body. One exception to this rule is a scabies infestation that is seen less frequently called crusted or Norwegian scabies, in which large areas of skin are infected with huge numbers (thousands) of itch mites; a person with this type of scabies is highly contagious.

Although pets can become infested with similar itch mites, they are not usually spread from humans to animals or from animals to humans.

What is the contagious period for scabies?

As long as an individual has about 10 to 15 itch mites on their body and has skin-to-skin contact with an uninfested person, that person is contagious for scabies and can pass the organisms to others. In addition, a person who has recently acquired scabies and is in the incubation period (without symptoms) is also contagious for scabies.
