Scabies (cont.)

What Follow-up Is Needed for a Scabies Infestation?

Itching can last for two weeks or more after successful treatment and does not necessarily indicate that the treatment failed. Repeat examination by a doctor in two weeks is recommended if there is persistent itching after treatment.

Is It Possible to Prevent Scabies?

It is difficult to prevent scabies. If a person is known to have scabies, they should not have close skin-to-skin contact with others until they have been treated. If one member of a household has scabies, all other household members, sexual partners, and close contacts should be treated simultaneously. Clothing, towels, and bedding from an affected person should be washed in hot water and dried in a dryer. If an article cannot be washed this way, it can be stored away from human contact for at least three days to eliminate mites because the mites will not survive longer than three days without contacting human skin.

In the hospital, staff should use gloves and gowns when treating patients who have a suspicious rash and itching.

What Is the Prognosis of Scabies?

Once properly diagnosed, treatment is generally very effective at curing scabies. Extensive scratching can cause abrasions on the skin, which may become secondarily infected with bacteria. Secondary infections are a significant problem in developing countries and the tropics.
