Rare Disease Day 2026

Global definition: A disease affecting ≤ 1 in 2,000 persons in a WHO‑defined region is considered rare.
Number of rare diseases: 6,000–10,000 identified worldwide.
Global burden: 300–450 million people affected.
Genetic origin: ≈ 80 % of rare diseases are genetic; 50–75 % manifest in childhood.
Treatment gap: ~95 % lack approved curative therapies.
India's estimate: 72–96 million people potentially affected.
National Policy for Rare Diseases (NPRD), 2021:
No prevalence‑based definition; diseases grouped by treatability.
Financial assistance up to Rs. 50 lakhs for patients with any of the 63 listed rare diseases at designated Centres of Excellence.
Union Budget 2026‑27:
7 additional rare diseases granted exemption from import duties on personal imports of drugs/medical supplies.
Production Linked Incentive (PLI) Scheme:
Rare diseases included as a focus area for the pharmaceutical sector.

Rare Disease Day was established in 2008 and is coordinated by EURORDIS in partnership with over 70 national patient alliances.
The observance falls on the rarest calendar day (28 Feb or 29 Feb) to symbolically represent the rarity of these conditions.
In India, lack of robust epidemiological data hampers a uniform prevalence‑based definition, leading to a policy‑driven categorisation.

Health equity: The NPRD aims to bridge diagnostic and therapeutic gaps for a large, underserved population.
Financial protection: Rs. 50 lakhs assistance reduces out‑of‑pocket expenditure, aligning with the government's broader goal of universal health coverage.
Budgetary focus: Inclusion of more diseases under duty‑exemption and the PLI scheme signals a strategic push to boost domestic production of orphan drugs, reducing reliance on imports.
Policy integration: Aligns with Ayushman Bharat, National Digital Health Mission, and the Vision for a Healthy India by addressing rare disease management within the larger health ecosystem.

Article 21 – Right to life and health; the state's duty to provide healthcare services.
National Health Policy 2017 (revised 2022) – Emphasises equitable access to healthcare, including for rare disease patients.
The Drugs and Cosmetics Act, 1940 – Provides the regulatory framework for import/export of medicines; duty‑exemption provisions under the budget modify this framework for rare disease drugs.
