Scabies is a parasitic, contagious infection of the skin that can spread quite quickly both from one area of the skin to another and from one person to another by simple skin to skin contact. It is caused by very tiny, almost invisible without a magnifying device, mites. These mites live on the skin and cause it to irritate and itch. They also lay eggs and multiply so you need to get rid of them quick if you don't want all your skin to become infected.
