Disease Report on Scabies Scabies is a very unpleasant skin disease to acquire. This disease is also known as the human itch mite. In the medical field, it is known as Sarcoptes scabiei var hominis. Scabies have been around for centuries. Scabies was first documented in a letter written by Dr. Giovan Cosimo Bonomo on July, 18, 1687, to Francesco Redi2.
