词源

The common-noun sense that functions as a hypernym over the names of various specific diseases predates the sense naming one specific disease in deer. The latter sense appears to have evolved through misparsing in which the former was misinterpreted as being the latter; but it is now an established term for that specific disease (thus, a fait accompli).
