Keep on reading to find out all the important information about Rare Disease Day at a glance, including its big picture, why it’s important, and how you can get involved. We’ll then share its brief history, three interesting facts about it, its future dates, and how you’ll never miss any important awareness event again.

The Most Important Information About Rare Disease Day at a Glance

1️⃣ The big picture: Rare Disease Day raises awareness about rare diseases, which individually affect fewer than 1 in 2,000 people but collectively impact millions globally. With over 7,000 rare conditions identified, the day advocates for improved medical research, diagnosis, and treatment while uniting families impacted by rare diseases and encouraging them to share their stories.

2️⃣ Why it is important: Rare diseases often lack sufficient research, funding, and treatment options, leaving many patients undiagnosed or without proper care. For example, of the 7,000 identified rare diseases, about 95% have no approved treatments, and many go unstudied by researchers, leaving patients reliant on off-label therapies which often create hurdles with insurance reimbursement. Advocacy efforts during Rare Disease Day aim to ensure equitable access to healthcare, raise funds for research, and promote understanding of the unique challenges faced by the rare disease community.

3️⃣ How you can get involved: You can participate in Rare Disease Day by raising awareness, supporting advocacy groups, or organizing events in your community:

1. #LightUpForRare: Get involved in Rare Disease Day by joining the #LightUpForRare campaign, during which iconic landmarks worldwide, including the Colosseum and the Empire State Building, light up in rare disease colors to show solidarity. You can participate by organizing a lighting event in your community or sharing photos and messages of support on social media with the hashtag #LightUpForRare. 
2. Support advocacy groups: Organizations like the Rare Disease Foundation, Global Genes, and the National Organization for Rare Disorders work tirelessly to advocate for rare disease patients. You can donate, volunteer, or attend their events to support their mission.
3. Spread the word: Raise awareness on Rare Disease Day by using the free campaign toolkit. Download social media graphics, videos, posters, and banners to share on your social media platforms. 

A Brief History of Rare Disease Day

When was this event established: Rare Disease Day was launched in 2008 by the European Organization for Rare Diseases to draw attention to rare conditions and their impact. Furthermore, the organization created the observance to highlight the challenges faced by those living with rare diseases and to unite the rare disease community globally.

How has it developed since then: Initially observed in Europe, Rare Disease Day is now a global event with participation from 106 countries. It has become a powerful platform for advocacy, raising funding for rare disease research and inspiring countless initiatives to improve healthcare systems and patient support worldwide. For instance, campaigns have led to the development of national registries for rare diseases and the expansion of orphan drug programs that help get treatments approved for rare conditions.

3 Interesting Facts About Rare Disease Day

1. Zebra symbolism: Medical students are taught, “When you hear hoofbeats, think horses, not zebras,” implying that common conditions are more likely than rare ones. Rare disease advocates have reclaimed the zebra as a symbol of their uniqueness and resilience.
2. The name game: Rare diseases often carry names rooted in their discovery. For example, Angelman syndrome honors physician Dr. Harry Angelman, while Lou Gehrig’s disease (ALS) bears the name of one of its most famous patients, and Marburg virus pays homage to the German town where scientists became ill with the disease’s first-known cases.
3. Rare, diverse, and far-reaching: Rare diseases span the medical spectrum, from well-known conditions like cystic fibrosis and most cancers to lesser-known ones like cat eye syndrome and Krabbe disease. Furthermore, about 72% of rare diseases are genetic and they can affect virtually any part of the body, including the heart, lungs, skin, and bones.
