Cancrum Otis: A severe, destructive, eroding ulcer of the cheek and lip. In the last century it was seen in delicate, ill-fed, ill-tended children between the ages of two and five. The disease was the result of poor hygiene. It was often fatal. The disease could, in a few days, lead to gangrene of the lips, cheeks, tonsils, palate, tongue, and even half the face; teeth would fall from their sockets. Synonyms: canker, water canker, noma, gangrenous stomatitis, gangrenous ulceration of the mouth.
Canker: An ulcerous sore of the mouth and lips, not considered fatal today. Synonym: aphthous stomatitis. See cancrum Otis.

In the early-nineteenth century it was called cynanche trachealis.

Synonyms: roup, hives, choke, stuffing, rising of the lights.
Debility: Abnormal bodily weakness or feebleness; decay of strength. This was a term descriptive of a patient's condition and of no help in making a diagnosis. Synonym: asthenia.
Diphtheria: An acute infectious disease acquired by contact with an infected person or a carrier of the disease. It was usually confined to the upper respiratory tract (throat) and characterized by the formation of a tough membrane (false membrane) attached firmly to the underlying tissue that would bleed if forcibly removed. In the nineteenth century the disease was occasionally confused with scarlet fever and croup.
Dropsy: A contraction for hydropsy. The presence of abnormally large amounts of fluid. Congestive heart failure

In the mid-nineteenth century, hives was a commonly given cause of death of children three years and under. Because true hives does not kill, croup was probably the actual cause of death in those children.
Hospital fever: See typhus.
Hydrocephalus: See dropsy.
Hydrothorax: See dropsy.
Icterus: See jaundice.
Inanition: Exhaustion from lack of nourishment; starvation.
Infection: In the early part of the last century, infections were thought to be the propagation of disease by effluvia (see above) from patients crowded together. "Miasms" were believed to be substances which could not be seen in any form--emanations not apparent to the senses. Such miasms were understood to act by infection.
Inflammation: Redness, swelling, pain, tenderness, heat, and disturbed function of an area of the body. In the last century, cause of death often was listed as inflammation of a body organ--such as, brain or lung--but this was purely a descriptive term and is not helpful in identifying the actual underlying disease.

Jaundice: Yellow discoloration of the skin, whites of the eyes, and mucous membranes, due to an increase of bile pigments in the blood. Synonym: icterus.

Spotted fever: See typhus.
Summer complaint: See cholera infantum.
Suppuration: The production of pus.
Teething: The entire process which results in the eruption of the teeth. Nineteenth-century medical reports stated that infants were more prone to disease at the time of teething. Symptoms were restlessness, fretfulness, convulsions, diarrhea, and painful and swollen gums. The latter could be relieved by lancing over the protruding tooth. Often teething was reported as a cause of death in infants. Perhaps they became susceptible to infections, especially if lancing was performed without antisepsis. Another explanation of teething as a cause of death is that infants were often weaned at the time of teething; perhaps they then died from drinking contaminated milk, leading to an infection, or from malnutrition if watered-down milk was given.
Tetanus: An infectious, often-fatal disease caused by a specific bacterium that enters the body through wounds. Synonyms: trismus, lockjaw.

The spelling has been left as is, you will see that the way we spell names today was not necessarily the way it was spelled years ago.
Credits: Many years ago when I first started genealogy research, I put out an inquiry about a disease and was sent this list. To the person that furnished it I wish to thank. This disease list has helped me tremendously and others that I have shared it with.
