Over 6,000 rare diseases are characterised by a wide range of conditions and symptoms that can vary not only between diseases but also among individuals with the same condition.

Seventy-two per cent of rare diseases are genetic, and nearly one in five cancers is classified as rare.

Some common symptoms may overlap with those of rare diseases, which can make diagnosis challenging and delay access to appropriate care. These conditions can impact daily life due to their long-term, evolving nature.

In many cases, there are limited treatment options, highlighting the need for continued research and support for individuals and families affected.

Rare Disease Day raises awareness for the 300 million people worldwide living with a rare disease, along with their families and carers.

The long-term goal of the Rare Disease Day campaign is to ensure equitable access to diagnosis, treatment, healthcare, social support, and opportunities for those affected by rare diseases.

Significant progress continues through joint international advocacy efforts for universal health coverage (UHC), a key part of the United Nations’ Sustainable Development Goals (SDGs). These efforts aim to create equitable health systems that address the needs of people with rare diseases, ensuring no one is left behind.

Rare Disease Day provides an opportunity to advocate for rare diseases as a human rights priority at local, national, and international levels, promoting a more inclusive society.

Since its launch in 2008, with events in just 18 countries, Rare Disease Day has grown into a global movement, now observed in over 100 countries.
