Rare Disease Day is observed on the last day of February. In 2026, it falls on February 28. This global event raises awareness for the over 300 million people living with a rare condition, defined in the United States as a disease affecting fewer than 200,000 people. By centering the observance on the rarest day of the year—February 29 during leap years—the holiday highlights the unique challenges, such as delayed diagnoses and limited treatment options, faced by patients and their families.

History of Rare Disease Day
The first Rare Disease Day was launched in 2008 by EURORDIS, a non-governmental alliance of patient organizations in Europe. The organizers chose February 29 because its rarity mirrors the nature of the conditions being highlighted. In non-leap years, the event is held on February 28 to ensure the message of support remains annual. The goal was to create a unified international voice for patients who often felt invisible within the broader healthcare system due to the scarcity of their specific conditions.
The movement crossed the Atlantic in 2009 when the National Organization for Rare Disorders (NORD) partnered with EURORDIS to organize events across the United States. Since then, the observance has expanded to over 100 countries. It has evolved from a grassroots awareness campaign into a powerful advocacy tool that influences policy, such as the Orphan Drug Act, and encourages pharmaceutical companies to invest in research for “orphan” diseases that might otherwise be neglected. 1
Why is Rare Disease Day important?
This day is critical because it addresses the “diagnostic odyssey” that many patients endure. On average, it takes several years and multiple consultations with specialists for a rare disease patient to receive an accurate diagnosis. By raising public and professional awareness, the holiday encourages earlier detection and reduces the isolation felt by those with ultra-rare conditions. It serves as a reminder that while a specific disease may be rare, the total number of people affected globally is significant.
The holiday also focuses on the need for equitable access to healthcare and specialized therapies. Currently, only about 5% of rare diseases have a treatment approved by the FDA. Rare Disease Day brings together researchers, clinicians, and policymakers to discuss the development of gene therapies and other innovative medicines. It emphasizes the importance of international data sharing, as the small number of patients for any single rare disease often requires global collaboration to conduct successful clinical trials.
- It advocates for the millions of people worldwide living with a rare condition.
- The day promotes the development of orphan drugs and specialized medical treatments.
- It helps reduce the social stigma and isolation associated with invisible illnesses.
- The holiday encourages healthcare providers to consider rare diagnoses in complex cases.
- It provides a platform for patient organizations to lobby for better legislative support.
How to Observe Rare Disease Day
One of the most visible ways to observe this day is by participating in the “Show Your Stripes” campaign. The zebra is the official symbol of the rare disease community, and wearing striped clothing or accessories helps start conversations about the challenges of the “medical zebra.” Many iconic landmarks, such as the Empire State Building and the Colosseum, are lit in green, blue, pink, and purple—the official colors of the holiday—to show global solidarity with patients.
Advocacy and education are also central to the day’s activities. Individuals can attend virtual or in-person seminars hosted by medical institutions to learn about recent breakthroughs in genetics and personalized medicine. Sharing personal stories or educational infographics on social media using the official holiday hashtag is a powerful way to reach a wider audience. Many people also choose to donate to research foundations or volunteer for organizations that provide emotional and financial support to families navigating the complexities of a rare diagnosis.
- Wear striped clothing to honor the zebra symbol of the rare disease community.
- Attend a local or national advocacy event to hear from patients and researchers.
- Share an educational video about the impact of rare diseases on social media.
- Donate to a non-profit organization that funds research for orphan diseases.
- Contact your local representatives to discuss policies that support rare disease patients.
