Outdated Disease Names: Identify the Illnesses That Affected Your Ancestors

By Susan Wenner
Decipher your ancestors' health maladies with these modern versions of archaic medical terms.

Did your ancestor suffer from King’s evil, St. Vitus dance, painter’s colic or—God forbid—bloody flux? If so, you may be conjuring up images of Great-great Grandpa suddenly coming down with a royal case of devilishness or bawling as he put a new coat of paint on the barn. But archaic medical terms have evolved since the days of yore.

Many old terms for diseases and ailments have been replaced by modern medical names. King’s evil, for example, is swollen neck glands (caused by tuberculosis). St. Vitus dance, sometimes called chorea or viper’s dance, was the term for nervous twitches. Painter’s colic, also known as Devonshire colic and dry bellyache, is lead poisoning. And bloody flux was another name for dysentery. To help you make sense of the ailments and diseases you find mentioned in your family medical records, here are some common antiquated terms and what they mean by today’s standards (keeping in mind that the diagnosis may not have been accurate):

  • ablepsia: blindness
  • acute angina: sore throat
  • apoplexy: paralyzed by stroke
  • bad blood, Lues disease, French or great pox: syphilis
  • Bethlehemite: mentally ill person
  • biliousness: jaundice caused by liver disease
  • black death, camp fever or ship’s fever: typhus
  • brain fever: meningitis
  • child bed fever: infection following childbirth
  • cholelithiasis: gall stones
  • congestive fever or chills: malaria
  • consumption, African consumption, lung sickness or galloping consumption: tuberculosis
  • coryza or catarrhal: cold or allergies
  • costiveness: constipation
  • croup: laryngitis, diphtheria or strep throat
  • dengue: infectious fever common in East Africa
  • dyspepsia: heartburn, indigestion or symptoms
  • falling sickness or caduceus: epilepsy
  • fatty liver: cirrhosis
  • green sickness or fever: anemia
  • grippe, grip or lagrippe: influenza (the flu)
  • infantile paralysis: polio
  • lumbago: back pain
  • lung or winter fever: pneumonia
  • mormal: gangrene
  • neuralgia: general term for discomfort (example: neuralgia in the head is a headache)
  • puerperal exhaustion: death due to childbirth
  • putrid fever, chin cough, bladder in throat, malignant sore throat or kruchhusten: diphtheria or whooping cough
  • quinsey: tonsillitis
