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. Close Contact Close and prolonged skin contact with someone who has scabies is most often to blame.

Lifestyle Risk Factors These choices or circumstances can increase the odds that you will be exposed to scabies or that it will be transmitted.

Occupation Caregivers who come into close contact with people, such as in hospital setting, may acquire the infection, even if good hygiene is practiced. 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.

Retreatment may be necessary if itching continues more than weeks after treatment or if new burrows or rash continue to appear. Anyone who is diagnosed with scabies, as well as his or her sexual partners and other contacts who have had prolonged skin-to-skin contact with the infested person, should be treated. Treatment is recommended for members of the same household as the person with scabies, particularly those persons who have had prolonged skin-to-skin contact with the infested person.

All persons should be treated at the same time to prevent reinfestation. If itching continues more than weeks after initial treatment or if new burrows or rash continue to appear if initial treatment includes more than one application or dose, then the time period begins after the last application or dose , retreatment with scabicide may be necessary; seek the advice of a physician.

Animals do not spread human scabies. However, the animal mite cannot reproduce on a person and will die on its own in a couple of days. Scabies is spread by prolonged skin-to-skin contact with a person who has scabies. Scabies sometimes also can be spread by contact with items such as clothing, bedding, or towels that have been used by a person with scabies, but such spread is very uncommon unless the infested person has crusted scabies.

Scabies is very unlikely to be spread by water in a swimming pool. Except for a person with crusted scabies, only about scabies mites are present on an infested person; it is extremely unlikely that any would emerge from under wet skin. Although uncommon, scabies can be spread by sharing a towel or item of clothing that has been used by a person with scabies. Scabies mites do not survive more than days away from human skin.

Items such as bedding, clothing, and towels used by a person with scabies can be decontaminated by machine-washing in hot water and drying using the hot cycle or by dry-cleaning. Items that cannot be washed or dry-cleaned can be decontaminated by removing from any body contact for at least 72 hours. Because persons with crusted scabies are considered very infectious, careful vacuuming of furniture and carpets in rooms used by these persons is recommended.

Back To Top. The rash and itching of scabies can persist for several weeks to a month after treatment, even if the treatment was successful and all the mites and eggs have been killed. Your health care provider may prescribe additional medication to relieve itching if it is severe. Symptoms that persist for longer than 2 weeks after treatment can be due to a number of reasons, including:. If itching continues more than weeks or if new burrows or rash continue to appear, seek the advice of a physician; retreatment with the same or a different scabicide may be necessary.

The doctor can examine the person, confirm the diagnosis of scabies, and prescribe an appropriate treatment. Sleeping with or having sex with any scabies infested person presents a high risk for transmission. The longer a person has skin-to-skin exposure, the greater is the likelihood for transmission to occur. Although briefly shaking hands with a person who has non-crusted scabies could be considered as presenting a relatively low risk, holding the hand of a person with scabies for minutes could be considered to present a relatively high risk of transmission.

However, transmission can occur even after brief skin-to-skin contact, such as a handshake, with a person who has crusted scabies. In general, a person who has skin-to-skin contact with a person who has crusted scabies would be considered a good candidate for treatment. To determine when prophylactic treatment should be given to reduce the risk of transmission, early consultation should be sought with a health care provider who understands:.
