Medically reviewed by University of Illinois. The most common signs and symptoms of scabies are intense itching pruritus , especially at night, and a pimple-like papular itchy rash. The itching and rash each may affect much of the body or be limited to common sites such as the wrist, elbow, armpit, webbing between the fingers, nipple, penis, waist, belt-line, and buttocks.
The rash also can include tiny blisters vesicles and scales. Scratching the rash can cause skin sores; sometimes these sores become infected by bacteria. Tiny burrows sometimes are seen on the skin; these are caused by the female scabies mite tunneling just beneath the surface of the skin. These burrows appear as tiny raised and crooked serpiginous grayish-white or skin-colored lines on the skin surface.
Because mites are often few in number only mites per person , these burrows may be difficult to find. They are found most often in the webbing between the fingers, in the skin folds on the wrist, elbow, or knee, and on the penis, breast, or shoulder blades. The head, face, neck, palms, and soles often are involved in infants and very young children, but usually not adults and older children.
Scabies usually is spread by direct, prolonged, skin-to-skin contact with a person who has scabies. Contact generally must be prolonged; a quick handshake or hug usually will not spread scabies. Scabies is spread easily to sexual partners and household members.
Scabies in adults frequently is sexually acquired. Scabies sometimes is spread indirectly by sharing articles such as clothing, towels, or bedding used by an infested person; however, such indirect spread can occur much more easily when the infested person has crusted scabies.
Diagnosis of a scabies infestation usually is made based on the customary appearance and distribution of the rash and the presence of burrows. Whenever possible, the diagnosis of scabies should be confirmed by identifying the mite, mite eggs, or mite fecal matter scybala. This can be done by carefully removing a mite from the end of its burrow using the tip of a needle or by obtaining skin scraping to examine under a microscope for mites, eggs, or mite fecal matter.
It is important to remember that a person can still be infested even if mites, eggs, or fecal matter cannot be found; typically fewer than mites can be present on the entire body of an infested person who is otherwise healthy. However, persons with crusted scabies can be infested with thousands of mites and should be considered highly contagious. On a person, scabies mites can live for as long as months. Off a person, scabies mites usually do not survive more than hours.
Products used to treat scabies are called scabicides because they kill scabies mites; some also kill eggs.
Always follow carefully the instructions provided by the doctor and pharmacist, as well as those contained in the box or printed on the label. When treating adults and older children, scabicide cream or lotion is applied to all areas of the body from the neck down to the feet and toes; when treating infants and young children, the cream or lotion also is applied to the head and neck. The medication should be left on the body for the recommended time before it is washed off.
Clean clothes should be worn after treatment. In addition to the infested person, treatment also is recommended for household members and sexual contacts, particularly those who have had prolonged skin-to-skin contact with the infested person. All persons should be treated at the same time in order to prevent reinfestation. Scabies: more than just an irritation.

I Accept Show Purposes. Common Causes There is only one actual cause of scabies, and that is mite infestation; the adult female is the culprit. The Mite The female mite burrows deep in the skin of an infected human host, laying eggs that hatch as larvae.
They are more difficult to see on dark skin, but you should be able to feel them. The scabies rash usually spreads across the whole body, apart from the head.
However, older people, young children and those with a weakened immune system may develop a rash on their head and neck. Many other things can cause itchy skin and rashes in babies and children.
Scabies is not usually a serious condition, but it does need to be treated. A pharmacist will recommend a cream or lotion that you apply over your whole body. It's important to read the instructions carefully.
