Etymology: "Septicaemias" is simply the plural of "septicaemia," the medical term for blood poisoning caused by bacteria circulating in the bloodstream. The noun is the form doctors use when speaking of several distinct cases or types of the condition at once. The base word "septicaemia" is built from Greek roots. The first element comes from "sēptikos," meaning "making putrid" or "causing decay," which in turn derives from "sēpein," "to rot." The second element, "-aemia," comes from Greek "haima," "blood," and appears in many medical terms, such as anaemia and leukaemia. Put together, the name literally describes a condition of putrefying blood. The term is a modern coinage built from these classical elements, not a word that ancient Greek physicians used for this disease. Its plural follows the regular English pattern of adding "-s," so the form is used whenever a writer needs to refer to more than one such infection.
