How many people have rare diseases? According to the National Institutes of Health (NIH), there are approximately 7,000 rare diseases affecting between 25 and 30 million Americans. This equates to 1 in 10 Americans, or one on every elevator and four on every bus.
With only four diagnosed patients in 27 years, ribose-5-phosphate isomerase deficiency is considered the rarest known genetic disease.
A rare disease is a health condition of low prevalence that affects a small number of people compared with other prevalent diseases in the general population. It is estimated that globally around 6000 to 8000 rare diseases exist with new rare diseases being reported in the medical literature regularly.

Malaria, pneumonia, diarrhoea, HIV and tuberculosis are preventable and treatable. But they are still killing children in large numbers. Major causes of death among children vary by age. Children under 5 are especially vulnerable to infectious diseases like malaria, pneumonia, diarrhoea, HIV and tuberculosis.
Regulators, scientists, clinicians and patient advocacy groups often cite ~7,000 as the number of rare diseases, or between 5,000 and 8,000 depending on the source (see Related links below). Why do estimates of the number of rare diseases vary so widely?
The European Union defines a disease or condition as rare if it affects fewer than 1 in 2,000 (1) people within the general population. Currently, there are over 6,000 (2) known rare diseases and new conditions are being described through medical literature on a regular basis.
Rare Diseases by the Numbers
1 in 2 people diagnosed with a rare disease are children. 3–15 years is a common timeline for diagnosis. 95% of rare diseases lack an FDA-approved treatment. People with rare diseases face 3–5 times higher medical costs than people with non-rare diseases.
NCATS Director Joni Rutter estimates that there are more than 7,000 rare diseases, but fewer than 600 have an FDA-approved treatment.
Cause 1: Ischaemic heart disease
Ischaemic heart disease was the leading single cause of deaths in Australia, responsible for 17,331 deaths in 2021, about one in 10 of total deaths that year. Males were more prone to the disease, accounting for 10,371 (59.8%) of the deaths compared to 6,960 (40.2%) for females.
Biosecurity has played a critical role in reducing risk and shaping our nation to become one of the few countries in the world to remain free from the world's most invasive pests and diseases.
Foot-and-mouth disease (FMD), African swine fever (ASF) and Lumpy skin disease (LSD) are animal diseases and are not present in Australia. They do not pose human health concerns. Avian influenza (bird flu, AI) is a global disease of birds and some strains may affect humans.
Cholera, bubonic plague, smallpox, and influenza are some of the most brutal killers in human history. And outbreaks of these diseases across international borders, are properly defined as pandemic, especially smallpox, which throughout history, has killed between 300-500 million people in its 12,000 year existence.
