Rare Disease Day is observed globally on 28th February (or 29th February in leap years, symbolically the rarest day) to underscore the unique challenges faced by this community.

  • Objective: It aims to achieve equity in social opportunities, healthcare, and access to diagnosis and therapies for rare disease patients.
  • Origin and Coordination: Established in 2008, it is coordinated by EURORDIS (European Organisation for Rare Diseases) in partnership with over 70 national alliance patient organisations.

Rare Disease

  • About: There is no single universal definition of a rare disease. It is primarily determined by prevalence, with a global/emerging consensus defining it as affecting ≤ 1 in 2,000 persons in a WHO-defined region.
  • Childhood and Genetic Link: A significant 50–75% of these conditions manifest during childhood or at birth, and approximately 80% are of genetic origin (e.g., Lysosomal storage disorders). The remaining include rare cancers, autoimmune conditions, and infectious diseases.
  • Global Context and Treatment Gap: Globally, there are 6,000–10,000 identified rare diseases, affecting an estimated 300–450 million people. Critically, ~95% of rare diseases currently lack approved curative treatments, posing a major public health challenge.
  • India's Position: India lacks a formal prevalence-based definition due to limited epidemiological data. Instead, the National Policy for Rare Diseases (NPRD), 2021, categorizes (Group 1, Group 2 and Group 3) disorders based on treatability and clinical experience, not strict numerical thresholds.
    • Despite the lack of a definition, an estimated 72–96 million people in India are affected by rare diseases
  • Policy Support in India: Under the NPRD 2021, financial support of up to Rs. 50 lakhs is provided to patients suffering from any of the 63 included rare diseases at designated Centres of Excellence.
