SCABIES - A SKIN DISEASE CAUSED BY AN ALMOST INVISIBLE ORGANISM, THE "ITCH MITE" (SARCOPTES scabiei). Crowded conditions and/or poor hygiene make it very easy for the mite to grow and spread.
HOW DO YOU GET SCABIES?
Scabies can be acquired very easily because it is a highly contagious condition. Scabies often spreads among school children quite rapidly, due to their close contact. In addition, family members, roommates and sexual partners are all candidates for spread of an infestation.
Usually scabies spreads by direct contact with another person who is infested. Even handholding games among children, or simply shaking hands, can result in scabies being transmitted from one individual to another. Exchanging clothing or sharing a bed or towels is also a means of spreading scabies. The scabies mite does not "jump" from one person to another and does not survive more than 3-4 days without skin contact.
WHAT HAPPENS?
The male and female mite mate on the skin surface. Then, the female burrows into the outermost layer of skin where she lays one to three eggs daily. In a few days the eggs hatch, and the larvae travel to the surface of the skin. The larvae become mites, and the cycle begins again.
The male mite dies after mating; the female dies after her egg-laying is completed, usually five weeks after reaching adulthood.
It is extremely difficult to see the female mite without the aid of a magnifying glass (length is 1/60 of an inch). The male is slightly smaller. However, linear zigzag burrows just below the surface of the skin are often visible to the naked eye. Usually, a grayish-white thread on the surface of the skin marks her trail. If your doctor suspects scabies, he/she will look for these characteristic trails in the spaces between the fingers, the back of the hands, elbows, armpits, breasts, groin, penis, along the belt line, on the back or the buttocks.
