Zymotic Diseases

Zymotic Diseases, the acute specific diseases which are regarded as being caused by the growth and multiplication within the system of a ferment or leaven. The term "zymotic death rate" is applied to the death rate from "seven principle zymotic diseases" (smallpox, measles, scarlet fever, diphtheria, whooping cough, fever, and diarrhoea). The zymotic death rate (mean annual death rate per thousand living) in England and Wales during the ten years (1871-80) was 3.26.

“If God give thee not only earth but heaven, that thou shouldest rule over sun, moon, and stars, and have rule over the highest of the sons of men, it would not be enough to satisfy thee, except thou hadst God himself.”
–Jeremiah Burroughs, The Rare Jewel of Christian Contentment
