RT Journal Article SR Electronic T1 Whence ‘zoster’? The convoluted classical origins of a sometimes illogical term JF Medical Humanities JO J Med Humanit FD BMJ Publishing Group Ltd and Institute of Medical Ethics SP 15 OP 18 DO 10.1136/medhum-2016-010926 VO 43 IS 1 A1 G D Schott YR 2017 UL http://mh.bmj.com/content/43/1/15.abstract AB The term ‘zoster’ is nowadays associated with ‘herpes zoster’, the condition resulting from reactivation of the latent varicella-zoster virus which causes shingles. But in antiquity the meaning of ‘zoster’, a Latin word originating from the Greek for a belt or girdle, was variously associated in men with a form of body armour which could enclose just one half of the body; in women with a garment worn around the waist and sometimes called a ‘zona’; and with a place, Zoster, linked mythologically then with the goddess Leto and her zona. Around 48 AD, the Roman physician Scribonius Largus became the first to associate ‘zona’ with ‘herpes’, and to attribute a medical meaning to ‘zona’, here an abbreviation of ‘zona ignea’ (‘fiery girdle’). Although in the past the terms ‘zoster’ and ‘zona’ were sometimes used interchangeably, today only ‘zoster’ remains—even when etymologically illogical in those patients whose zoster rash occurs in body areas other than the trunk.
