Limited Information
Because rare diseases affect so few people, there is often less information available about symptoms, progression and treatment options.
Understanding rare diseases and supporting patients
Access educational resources, disease information and external support networks for patients and caregivers navigating rare conditions.
A rare disease diagnosis can feel isolating, but resources, information and support networks are available for patients and families.
A disease is considered rare when it affects fewer than 1 in 2,000 people. While each individual rare disease affects a small number of people, there are more than 7,000 known rare diseases - which means collectively, they touch the lives of millions.
Living with a rare disease comes with unique challenges that can feel overwhelming. Understanding these challenges is the first step toward addressing them.
Because rare diseases affect so few people, there is often less information available about symptoms, progression and treatment options.
The lack of awareness can lead to delayed or incorrect diagnoses, sometimes taking years before patients receive the right answers.
Many rare diseases have inadequate or no approved treatments, leaving patients and families searching for solutions.
Where treatments do exist, access can be inconsistent, varying by country, region or healthcare system.
