Prevalence and Incidence of Respiratory diphtheria


About prevalence and incidence statistics: The term 'prevalence' of Respiratory diphtheria usually refers to the estimated population of people who are managing Respiratory diphtheria at any given time. The term 'incidence' of Respiratory diphtheria refers to the annual diagnosis rate, or the number of new cases of Respiratory diphtheria diagnosed each year. Hence, these two statistics types can differ: a short-lived disease like flu can have high annual incidence but low prevalence, but a life-long disease like diabetes has a low annual incidence but high prevalence. For more information see about prevalence and incidence statistics.

Incidence (annual) of Respiratory diphtheria: Approximately 0.001 per 100,000 in USA (DBMD)
Incidence Rate: approx 1 in 100,000,000 or 0.00% or 2 people in USA [about data]
Prevalance of Respiratory diphtheria: Approximately 0.001 cases per 100,000 population in the U.S. since 1980; before the introduction of vaccine in the 1920s incidence was 100-200 cases per 100,000 population. Diphtheria remains endemic in developing countries. The countries of the former Soviet Union have reported >150,000 cases in an epidemic which began in 1990.1
