Etymology: "Typhuses" is simply the plural of "typhus," so the story belongs to the singular. The name comes from Ancient Greek "tûphos," meaning "fever" or "stupor," a word that itself derives from "túphō," "to smoke." The link seems to be that a fever clouds the mind and dulls the senses, much like smoke obscures the air. Modern scientists later adopted the Greek term in New Latin, the scholarly Latin of early modern and modern science, to name the disease. The plural form appears when writers need to speak of more than one kind of the illness, such as the louse-borne epidemic form and the flea-borne murine form, each caused by a different bacterium. In that sense, "typhuses" is less a grammatical oddity than a reflection of medicine's growing ability to separate related diseases that once shared one name.

Synonyms: typhoid fevers, typhus infections
