Scabies

Scabies is an ancient disease. Archeological evidence from Egypt and the Middle East suggests that scabies was present as early as 494 BC. The first recorded reference to scabies is believed to be from the Bible (Leviticus, the third book of Moses) ca. 1200 BC. Later in fourth century BC, the ancient Greek philosopher Aristotle reported on "lice" that "escape from little pimples if they are pricked"; scholars believe this was actually a reference to scabies.

Nevertheless, it was Roman physician Celsus who is credited with naming the disease "scabies" and describing its characteristic features. The parasitic etiology of scabies was later documented by the Italian physician Giovanni Cosimo Bonomo (1663–99 AD) in his famous 1687 letter, "Observations concerning the fleshworms of the human body." With this (disputed) discovery, scabies became one of the first diseases with a known cause.
