typhoid (adj.)

1800, literally "resembling typhus," from typhus + -oid. The noun is from 1861, a shortened form of typhoid fever (1845), so called because it originally was thought to be a variety of typhus. Typhoid Mary (1909) was Mary Mallon (d.1938), a typhoid carrier who worked as a cook and became notorious after it was learned she unwittingly had infected hundreds in U.S.
