  • n. A period of invasion of a week or less, characterized by a gradually increasing temperature, with morning remissions and evening exacerbations, want of appetite, thirst, dry and coated tongue, frequent pulse, headache, often nose-bleed, usually constipation, often slight diarrhea, slightly tympanitic abdomen, with perhaps some tenderness and gurgling in the right iliac region, some enlargement of the spleen, perhaps slight delirium at night, and some bronchitis.
  • n. A period of continued pyrexia (fever) in which the temperature ceases to rise, and in which its daily variations are less. This period (fastigium) lasts for a week or two. The want of appetite, thirst, dry tongue, frequent pulse, headache, and bronchitis continue or are increased. The tympanitis, splenic enlargement, and delirium become more pronounced. Three or four soft yellow stools are passed daily. About the beginning of this period an eruption of small, pink, slightly raised spots appears on the skin, especially of the back and abdomen.
  • n. A period of defervescence, in which the fever gradually disappears and all the symptoms improve. This may last about a week. Cases vary much from this typical progress, and may be marked in addition by intestinal hemorrhage, perforation of the intestinal wall with collapse and peritonitis, thrombosis of the larger veins, especially the femoral, pneumonia, lobular and (rarely) lobar, or meningitis. Relapses (after a normal temperature has been reached) and recrudescences (before the fever has entirely disappeared) are not very uncommon. The mortality varies, but the average of recent reports is not far from 10 per cent. The main anatomical features are inflammation of Peyer's patches and of the solitary glands of the small and sometimes of the large intestine, with inflammation of the mesenteric lymphatic glands. Persons between fifteen and thirty years of age seem to be most frequently attacked. A previous attack produces a certain but not complete protection. The contagium seems to be given off from the sick mainly by the stools. The contamination of food and drink seems to be the most important mode of ingress. Personal contact does not materially increase exposure. Typhoid fever is now believed to be caused by a microscopic parasitic organism or bacillus, in length about one third the diameter of a red blood-corpuscle, in thickness about one third of its length, with rounded ends, mobile, forming spores at a temperature between 30° and 42°C., but not at lower temperatures, and forming minute brownish-yellow colonies on gelatin, which it does not soften. For synonyms, see phrases above.
  • n. A smith; an artisan.

Middle English, from Old English fefor and from Old French fievre, both from Latin febris.

From Middle English, from Old French fievre, reinforced by native Old English fēfor, from Latin febris ("a fever"), from ferveō ("to be hot, burn, boil"); or perhaps literally 'a trembling', akin to Greek φέβεσθαι (febesthai, "to flee affrighted"), φόβος (phobos, "flight, panic fear, fear, terror").
