Medical Definition of diphtheria. : an acute febrile contagious disease typically marked by the formation of a false membrane especially in the throat and caused by a bacterium of the genus Corynebacterium (C. diphtheriae) which produces a toxin causing inflammation of the heart and nervous system.
The case-fatality rate for diphtheria has changed very little during the last 50 years. The overall case-fatality rate for diphtheria is 5%â10%, with higher death rates (up to 20%) among persons younger than 5 and older than 40 years of age.Before there was treatment for diphtheria, the disease was fatal in up to half of cases. The incubation period of diphtheria is 2-5 days (range, 1-10 days).Diphtheria can involve almost any mucous membrane. For clinical purposes, it is convenient to classify diphtheria into a number of manifestations, depending on the site of disease:iphtheria once was a major cause of illness and death among children. The U.S. recorded 206,000 cases of diphtheria in 1921, resulting in 15,520 deaths.
