World Rare Disease Day 2025 – Theme, Importance, Quiz

World Rare Disease Day is celebrated on 28 February annually. If we read through the US’s Orphan Drug Act of 1983, it describes Rare disease as any disease affecting fewer than 200,000 people. Sadly, at this point, many of these rare diseases are without cures or treatment due to the significant absence of people available to participate in scientific studies.  Across the globe, people with rare diseases struggle to receive a proper diagnosis and get treatment. Every year, EURORDIS (The European Organization for Rare Disorders), organizes the Rare Disease Day to increase awareness about the rare medical conditions and to comfort both patients and their family.

World Rare Disease Day 2025 History

In the United States, a rare disease is defined as a condition that affects fewer than 200,000 people in the US. This definition was created by the US Congress during the 1983 Orphan Drug Act. In Europe, a disease defined as rare when it affects fewer than 1 in 2,000 people. The World Health Organization (W.H.O.) has suggested that a rare disease should be defined as one with a frequency of less than 6.5 – 10 per 10,000 people. So every country defines a rare disease most appropriate in the context of its own population, the health care system and resources.

In India, there has no standard definition for rare diseases. Considering our population, ORDI (Organization for Rare Disease in India) suggests a disease be defined as rare if it affects 1 in 5,000 people or less. Rare diseases are also known as orphan diseases because drug companies were not interested in adopting them to develop treatments. There are more than 7000+ Rare Diseases are reported across the globe, and 1 in 20 Indians, around 70 million is affected by one of these RDs.
