Scabies is an easily spread skin condition caused by a mite known as the Sarcoptes scabiei. It is a common condition among the skin conditions which can cause severe itching. Scabies mites can be seen with a magnifying glass or microscope. The scabies mites crawl but are unable to fly or jump. They are immobile at temperatures below 20 C, although they may survive for prolonged periods at these temperatures. Scabies can affect anyone at any age (including a baby or child). Although scabies can be bothersome, the infestation can usually be treated effectively.
