Prevention
Well it is VERY 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.
When in the hospital, staff should use gloves and gowns when treating patients who have a suspicious rash and itching.
