A rare disease has such a low prevalence in a population that a doctor in a busy general practice would not expect to see more than one case a year. Rare diseases, including those of genetic origin, are life-threatening or chronically debilitating diseases which are of such low prevalence that special combined efforts are needed to address them. As a guide, low prevalence is taken as prevalence of less than 5 per 10,000 in the Community [1] http://europa.eu.int/comm/health/ph_information/documents/ev20040705_rd05_en.pdf .

Rare diseases will vary from population to population, as a disease that is rare in some populations may be common in another. This is especially true of some genetic and infectious diseases. 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.
