During an identified scabies outbreak, staff members who have been providing care to an identified case should not be rotated to other resident care units until 24 hours after completion of the staff member's scabicidal treatment. The case should also be isolated from other residents for 24 hours.
Common Symptoms
Severe itching (pruritus), especially at night, is the earliest and most common symptom of scabies. A pimple-like (papular) itchy (pruritic) “scabies rash” is also common. Itching and rash may affect much of the body or be limited to common sites such as: Between the fingers.

Parasites - Scabies
Human scabies is caused by an infestation of the skin by the human itch mite (Sarcoptes scabiei var. hominis). The microscopic scabies mite burrows into the upper layer of the skin where it lives and lays its eggs. The most common symptoms of scabies are intense itching and a pimple-like skin rash.
