Rare disease - Prevalence

As a guide, low prevalence is taken as prevalence of less than 5 per 10,000 in the community [1].

The NIH's Office of Rare Diseases states that, "an orphan or rare disease is generally considered to have a prevalence of fewer than 200,000 affected individuals in the United States" [2].

For example, cystic fibrosis is a rare genetic disease in most parts of Asia but is relatively common in some Eurasian populations. Many infectious diseases, such as tropical diseases, are rare outside a given geographic area.
