Sarx (the flesh)
Koptein (to smite or cut)
LATIN SCABERE (TO SCRATCH). TODAY, THE TERM SCABIES REFERS TO THE SKIN LESIONS PRODUCED BY THIS mite.

PATHOPHYSIOLOGY
The larvae leave the burrow to mature on the skin. Fewer than 10% of the eggs laid result in mature mites.
An affected host harbors approximately 11 adult female mites during a typical infestation. The eggs hatch in 3-4 days.
The female mite burrows into the epidermis of the host using her jaws and front legs, where she lays up to 3 eggs per day for
the duration of her 30-60 day lifetime.
After mating, the male mite dies.

Pathophysiology
Individuals who already are sensitized from a prior infestation can develop symptoms within hours.
This reaction is responsible for the intense pruritis, which is the hallmark of the disease.
A delayed type IV hypersensitivity reaction to the mites, their eggs, or scybala (packets of feces) occurs approximately 30 days
after infestation.

Scabies usually is transmitted by direct contact with an affected individual.
Although it has been disputed, it is believed possible to become infested by indirect contact with the personal items or clothing of an affected person because the mite can survive away from the skin for 2-5 days.

In 1848, the Norwegians Danielssen and Boeck described a highly contagious variant of scabies that occurs in immunocompromised patients.
This rare form of scabies occurs in elderly or Because of an impaired antibody response, i.e HIV & AIDS these individuals can be infested with thousands to a couple million mites.
