Rare Disease Day is February 28. The last day of February each year shines a light on the many types of rare diseases and the millions of people living with one. Research is making progress but more is needed. Because rare diseases are diverse, it requires international scientific cooperation to lead to developing better diagnostic tools, treatments and cures, as well as improved health and social care for patients and their families. Rare Disease Day is aimed at raising awareness about these diseases and challenges and to encourage more progress be made.
