Prevalence and Incidence of Duchenne Muscular Dystrophy

Duchenne Muscular Dystrophy: Rare Disease

Duchenne Muscular Dystrophy is listed as a "rare disease" by the Office of Rare Diseases (ORD) of the National Institutes of Health (NIH). This means that Duchenne Muscular Dystrophy, or a subtype of Duchenne Muscular Dystrophy, affects less than 200,000 people in the US population.

Incidence (annual) of Duchenne Muscular Dystrophy:

about 1 in 3000 males1. ... see also overview of Duchenne Muscular Dystrophy.

Incidence Rate:

approx 1 in 6,000 or 0.02% or 45,333 people in USA [Source statistic for calcuation: "about 1 in 3000 males1." -- see also general information about data sources]

Incidence extrapolations for USA for Duchenne Muscular Dystrophy:

45,333 per year, 3,777 per month, 871 per week, 124 per day, 5 per hour, 0 per minute, 0 per second. [Source statistic for calculation: "about 1 in 3000 males1." -- see also general information about data sources]

Prevalance of Duchenne Muscular Dystrophy:

All are X-linked and affect mainly males --- an estimated 1 in 3500 boys worldwide. (Source: Genes and Disease by the National Center for Biotechnology)

About prevalence and incidence statistics:

The term 'prevalence' of Duchenne Muscular Dystrophy usually refers to the estimated population of people who are managing Duchenne Muscular Dystrophy at any given time. The term 'incidence' of Duchenne Muscular Dystrophy refers to the annual diagnosis rate, or the number of new cases of Duchenne Muscular Dystrophy 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.
