Muscular Dystrophy: Rare Disease

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 Muscular Dystrophy, or a subtype of Muscular Dystrophy, affects less than 200,000 people in the US population.

Incidence (annual) of Muscular Dystrophy:

500 - 600 male newborns are diagnosed with muscular dystrophy each year in the US, Duchenne and Becker types, Genetics Home Reference website ... see also overview of Muscular Dystrophy.

Incidence Rate:

approx 1 in 544,000 or 0.00% or 500 people in USA [Source statistic for calcuation: "500 - 600 male newborns are diagnosed with muscular dystrophy each year in the US, Duchenne and Becker types, Genetics Home Reference website" -- see also general information about data sources]

Incidence extrapolations for USA for Muscular Dystrophy:

500 per year, 41 per month, 9 per week, 1 per day, 0 per hour, 0 per minute, 0 per second.

Incidence of types of Muscular Dystrophy:

About prevalence and incidence statistics:

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