Prevalence and Incidence of Hemochromatosis

Prevalance of Hemochromatosis:

more than 1 million Americans (CDC); 5 per 1000 in Caucasians (NIDDK); 1-in-200 to 1-in-300 ... see also overview of Hemochromatosis.

Prevalance Rate:

approx 1 in 272 or 0.37% or 1 million people in USA [Source statistic for calcuation: "more than 1 million Americans (CDC); 5 per 1000 in Caucasians (NIDDK); 1-in-200 to 1-in-300" -- see also general information about data sources]

Undiagnosed prevalence of Hemochromatosis:

1.5 million Americans (Hemochromatosis Foundation) ... see also misdiagnosis of Hemochromatosis.

Undiagnosed prevalence rate:

approx 1 in 181 or 0.55% or 1.5 million people in USA [about data] ... Note: this rate calculation uses the following statistic: 1.5 million Americans (Hemochromatosis Foundation)

Prevalance of Hemochromatosis:

About 5 people in 1,000 (0.5 percent) of the U.S. Caucasian population carry two copies of the hemochromatosis gene and are susceptible to developing the disease. (Source: excerpt from Hemochromatosis: NIDDK)

About prevalence and incidence statistics:

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