Armpits, groin, scrotum, buttocks, navel, waist, and ankles can be involved. The face and neck are usually spared. In infants, the rash can involve the face and scalp. The rash usually looks the same on both sides of the body. Cause of Scabies Scabies mite Scabies comes from skin-to-skin contact with someone who has scabies.
After contact, a person will come down with scabies rash in 4 to 6 weeks. Itching is the first symptom. The most common symptoms of scabies are intense itching and a pimple-like skin rash. The scabies mite usually is spread by direct, prolonged, skin-to-skin contact with a person who has scabies. Scabies is found worldwide and affects people of all races and social classes. Scabies can spread rapidly under crowded conditions where close body and skin contact is frequent. Institutions such as nursing homes, extended-care facilities, and prisons are often sites of scabies outbreaks.
Child-care facilities also are a common site of scabies infestations. Crusted scabies is a severe form of scabies that can occur in some persons who are immunocompromised have a weak immune system , elderly, disabled, or debilitated. It is also called Norwegian scabies.
Persons with crusted scabies have thick crusts of skin that contain large numbers of scabies mites and eggs. Persons with crusted scabies are very contagious to other persons and can spread the infestation easily both by direct skin-to-skin contact and by contamination of items such as their clothing, bedding, and furniture. Persons with crusted scabies may not show the usual signs and symptoms of scabies such as the characteristic rash or itching pruritus.
Persons with crusted scabies should receive quick and aggressive medical treatment for their infestation to prevent outbreaks of scabies. If a person has never had scabies before, symptoms may take weeks to develop.
In a person who has had scabies before, symptoms usually appear much sooner days after exposure. 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.
