Rare diseases are health conditions that affect a small percentage of the population, often defined as fewer than 200,000 people in the United States. These diseases can be genetic, infectious, or autoimmune, and many have no known cure. Because they are so uncommon, patients often face challenges in getting accurate diagnoses and effective treatments.
Research on rare diseases is crucial, as it can lead to better understanding and potential therapies. Organizations like the National Organization for Rare Disorders (NORD) work to raise awareness and support for those affected, helping to connect patients with resources and information about their conditions.
