Rare Disease Day is an observance held on the last day of February to raise awareness about diseases that most people will not know of, as well as to improve access to treatment.
It’s important for average people to get more informed about the ways that rare diseases affect individuals and create a space where there are more opportunities to show support and perhaps even help in some ways!
How to Celebrate Rare Disease Day
EURORDIS (The European Organization for Rare Diseases) says that treatment for many rare diseases is insufficient, and some people’s quality of life is greatly hindered by inequality, simply because people have never heard of their disease, or do not understand the disease and the patient’s needs.
Show support for Rare Disease Day by observing the day with some of these ideas:
Share Rare Disease Experiences
Each year, people affected by rare diseases are encouraged to share pictures and their stories with the world. The Rare Disease Day website offers opportunities for folks from all over the globe to learn more about each other by posting their own stories and reading other people’s stories.
The website contains hundreds of stories in many languages, creating a worldwide community of people with rare diseases who can feel more seen and heard.
Attend a Rare Disease Day Event
Get connected with people in the local community or across the planet by joining in with events for Rare Disease Day, whether online or in real life.
Check out the Rare Disease Day website for more information about events that are taking place in many countries and a wide range of languages.
Host a Rare Disease Day Event
Those who are interested in raising awareness and promoting the stories of those who have rare diseases may be interested in hosting an event in their local community or online.
Whether it is an informal gathering of friends to raise awareness and support, a book club where a biography of a person with a rare disease is discussed, or an informational gathering with a medical professional as a guest speaker, the opportunities are almost endless.
The Rare Disease Day website offers plenty of resources including downloadable kits, info-packs, posters and many other tools!
Rare Disease Day Timeline
The United States enacts the Orphan Drug Act
The Orphan Drug Act became law, creating tax credits, grants, and seven years of market exclusivity to spur the development of treatments for rare diseases affecting fewer than 200,000 people in the U.S.
European Union adopts Orphan Medicinal Products Regulation
The European Parliament and Council approve Regulation (EC) No 141/2000 on orphan medicinal products, establishing incentives and a formal EU framework for developing drugs for rare conditions.
EU Orphan Regulation 141/2000 enters into force
Regulation (EC) No 141/2000 takes effect, enabling centralized designation of orphan medicines and coordinated support across member states for therapies targeting rare diseases.
EU issues “Rare Diseases: Europe’s Challenges” communication
The European Commission publishes a strategy document on rare diseases, calling for better coordination, national plans, and improved access to diagnosis, information, and care.
Council recommends national plans for rare diseases
The Council of the European Union adopts a recommendation urging member states to develop national plans for rare diseases by 2013 to strengthen the organization of care and research.
European Reference Networks framework established
Directive 2011/24/EU on patients’ rights in cross‑border healthcare is adopted, creating the legal basis for European Reference Networks that later connect expert centers on many rare diseases.
Launch of the first European Reference Networks
The European Commission formally launches 24 European Reference Networks, linking hundreds of specialized centers to share expertise and improve diagnosis and treatment for patients with rare and complex diseases.
History of Rare Disease Day
Since 2008, EURORDIS has been putting in place social networks to help support individuals with rare diseases and their families, as well as coordinating events for Rare Disease Day at an international level.
The first time the event was celebrated, the day took place in leap year, so it was observed on February 29. In non leap years, the day is celebrated on February 28.
The reason the month of February was chosen for this celebration is because it is also a “rare” month, in that it sometimes has an extra day at the end.
So the common theme offers a nod to the uniqueness of the people who experience rare diseases by placing it on a unique and special day.
Each year, the celebration of the day looks a little different too. For instance, in 2010, Rare Disease Day featured balloon releases, marathons, auctions and tree planting events to raise awareness.
These types of events can be sponsored by all sorts of different communities, health care centers, hospitals, charitable foundations and so much more.
Starting 2011, Rare Disease Day began sponsorship by the National Institutes for Health (NIH), specifically by the National Center for Advancing Translational Sciences (NCATS).
The hope is that the collaboration between a wide variety of scientists, researchers, medical professionals and others will bring more attention to rare diseases with the hope of finding treatments and cures.
Rare Disease Day: Key Facts That Put “Rare” in Perspective
Rare diseases are often thought of as isolated and uncommon, but the facts tell a much broader story. Definitions vary from country to country, thousands of different conditions exist, and when viewed together, rare diseases affect hundreds of millions of people worldwide.
Understanding how they are defined, how many people they impact, and why research and policy matter helps explain why rare diseases are a global health priority rather than a fringe issue.
Different Countries Define “Rare” in Very Different Ways
What counts as a rare disease depends on where a person lives.
In the United States, a condition is considered rare if it affects fewer than 200,000 people nationwide, while the European Union generally uses a threshold of no more than 5 in 10,000 people and some countries, like Japan, set yet another numerical cutoff.
These differing definitions affect which conditions qualify for special research incentives and reimbursement support, so the same diagnosis can be “rare” in one jurisdiction and not in another.
Collectively, Rare Diseases Are Not Rare at All
Individually, each rare disease affects a small number of people, but taken together they are a major global health issue.
More than 7,000 identified rare diseases impact an estimated 300 million people worldwide, which is roughly 5 percent of the global population, and over 25 million people in the United States alone. This “paradox of rarity” is why health agencies increasingly treat rare conditions as a public health priority rather than one-off exceptions.
Most Rare Diseases Start in the Genes and in Childhood
Around 70 to 80 percent of rare diseases are believed to have a genetic origin, and the majority of those appear during childhood.
Many are severe, chronic, and multi-system conditions that shorten life expectancy, which is why rare diseases are a leading cause of death in infants and young children in high‑income countries, despite each condition being individually uncommon.
The “Orphan Drug” Act Transformed Industry Interest in Rare Conditions
Before the U.S. Orphan Drug Act of 1983, pharmaceutical companies largely ignored rare diseases because potential markets were so small.
The law created tax credits, fee waivers, and seven years of market exclusivity for drugs targeting rare conditions, and it triggered a dramatic change: the FDA has now granted thousands of orphan drug designations and approved hundreds of rare-disease therapies, compared with only a handful before the act existed. Similar “orphan” frameworks later spread to Europe and other regions.
Patients Commonly Endure Years in a “Diagnostic Odyssey”
People with rare diseases often spend years cycling through specialists and tests before getting a name for their condition.
compiled by rare disease organizations show that many patients wait four to six years or longer for an accurate diagnosis and often receive multiple misdiagnoses along the way, which can delay appropriate care, genetic counseling, and access to clinical trials.
Whole-Genome Sequencing Can Cut Diagnosis Times from Months to Days
Advances in DNA technology are starting to shorten the rare disease diagnostic odyssey.
In a randomized clinical trial of critically ill infants and children, rapid whole-genome sequencing delivered a genetic diagnosis in a median of 13 days, compared with 107 days using standard testing approaches.
Because whole-genome sequencing reads nearly all of a person’s DNA, it can reveal disease-causing variants that traditional tests and even exome sequencing miss.
The Vast Majority of Rare Diseases Still Lack Approved Treatments
Despite progress in orphan drug development, most rare disease patients still have no specific therapy.
Advocacy and research groups estimate that about 95 percent of rare diseases currently have no FDA-approved treatment, leaving clinicians to rely on symptom management, off-label use of existing drugs, or participation in experimental trials.
This treatment gap is one reason rare diseases remain an area of intense scientific and policy focus.
