Why in news?
The Union Health and Family Welfare ministry recently approved the National Policy for Rare Diseases 2021.
What are rare diseases?
- Rare diseases are broadly defined as diseases that infrequently occur in a population; three markers are used:
- the total number of people with the disease
- its prevalence
- the availability/non-availability of treatment options
- WHO defines rare disease as often debilitating lifelong disease or disorder with a prevalence of 1 or less, per 1000 population.
- However, different countries have their own definitions.
- It is defined in a way to suit their specific requirements and in context of their own population, health care system and resources.
- As per an estimate, there are 7,000 known rare diseases with an estimated 300 million patients in the world.
- Of this, 70 million are in India.
- They include inherited cancers, autoimmune disorders, congenital malformations, Hirschsprung’s disease, Gaucher disease, cystic fibrosis, muscular dystrophies and Lysosomal Storage Disorders (LSDs).
