where does the scabies came from?

Scabies is caused by the mite Sarcoptes scabiei. Scabies mites are attracted to the warmth and smell of humans. Female mites burrow into the skin, creating small, threadlike tunnels that you can sometimes see. The mites lay eggs and leave feces in these tunnels.

	Scabies usually is spread by close, intimate contact, such as sleeping in the same bed with or touching someone who has scabies. The scabies mite cannot fly or jump, and it moves very slowly.

	Scabies mites only live for several days away from human skin. During this time, the mites may spread to other people. Mites usually spread through skin-to-skin contact. But they can also spread from contact with clothing, bed linens, and other household and personal items.

	A mite burrows very quickly under the skin, especially in areas where it is rough or wrinkled, such as the elbows, knuckles, and knees. Touching or scratching an area that is infested with mites can spread them to other parts of the body.

	After burrowing under the skin, a female mite lays eggs before she dies. The eggs hatch into larvae several days later. These larvae move to the skin's surface and become adults within about 2 weeks. This cycle continues until the mites are killed.


The scabies mite that infests humans does not live on dogs or other pets. And animal-transmitted scabies mites do not survive or reproduce on humans. But they can live long enough on humans to cause itchy hives or raised bumps that last a few days.
