Origin

Late Middle English (denoting the venom of a snake): from Latin, literally 'slimy liquid, poison'. The earlier medical sense, superseded by the current use as a result of improved scientific understanding, was 'a substance produced in the body as the result of disease, especially one capable of infecting others'.

A virus was originally the venom of a snake, and was an English borrowing of a Latin word meaning ‘slimy liquid’ or ‘poison’, that is also the source of virulent (Late Middle English). Early medical practitioners used the word for a substance produced in the body as the result of disease. The modern meaning dates from the late 19th century. The computer virus dates from the early 1970s.
