A rare disease is a health condition that affects fewer than 1 in 2,000 people. Although each condition is uncommon, there are over 7,000 recognised rare diseases, meaning many families live with complex and often misunderstood medical needs.
Rare diseases may affect physical health, development, learning, or communication, and often require specialist care.
Some conditions may remain undiagnosed for years (“syndromes without a name”). Regardless of diagnosis, children are entitled to appropriate educational and healthcare support.
