Causes
A microscopic mite called the human itch mite (Sarcoptes scabiei var. hominis) burrows into the upper layer of a person's skin, where it lives and lays two to three eggs each day.

Clinical manifestations
-
Itching, often severe and usually worse at night
Thin, irregular burrow tracks made up of tiny blisters or bumps on your skin

Pathophysiology
Larvae migrate to the skin surface and burrow into the intact stratum corneum to make short burrows, called molting pouches
Larvae molt into nymphs, which molt once into larger nymphs before becoming adults.
-
The female makes a serpentine burrow using proteolytic enzymes to dissolve the stratum corneum of the epidermis, laying eggs in the process
The female S scabiei var hominis mite lays 60-90 eggs in her 30-day lifespan, although less than 10% of the eggs result in mature mites.
Transmission of impregnated females from person-to-person occurs through direct or indirect skin contact.
Nursing management

Nursing intervention
