Scabies is one of the several other skin conditions that causes itching and rashes. It is contagious and can spread easily through close contact. It can affect people of all ages, gender and ethnic group. A dermatologic condition triggered by sarcoptes scabiei – and eight legged microscopic mite; it can affect the immunocompromised, the elderly and those housed in institutional settings. Itching, rashes, sores and thick crusts are the known symptoms that lead to scabies.

CAUSES:

Intensely pruritic skin infestation caused by the host-specific mite, sarcoptes scabiei var hominis usually transmitted through direct contact with an infested individual.
Mites can survive up to 3 days from human skin. Same is the case with fomites such as infested bedding or clothing - an infrequent source of transmission.

CLINICAL PICTURE:

Common, extremely pruritic eruption consisting of papules, pustules, vesicles, and linear burrows.
Distribution - wrists, finger web spaces, toe webs, umbilicus, genital area, breast [women], axillae. May involve the face and scalp in infants.

Prevalence rates are higher in children and sexually active individuals than others.
