Rare Disease Day is the globally-coordinated movement on rare diseases, working towards equity in social opportunity, healthcare, and access to diagnosis and therapies for people living with a rare disease. By Sharing your colours via social media, events, illuminating buildings, monuments and homes, by sharing experiences online and with friends, by calling on policy makers and shining the light on people living with a rare disease, collectively we aim to change and improve lives of the 300 million people worldwide.
