What Is Rare Disease Day?

Rare Disease Day takes place on the last day of February each year. The main objective of Rare Disease Day is to raise awareness amongst the general public and decision-makers about rare diseases and their impact on patients’ lives.

Building awareness of rare diseases is so important because 1 in 20 people will live with a rare disease at some point in their life. Despite this, there is no cure for the majority of rare diseases and many go undiagnosed. Rare Disease Day improves knowledge amongst the general public of rare diseases while encouraging researchers and decision-makers to address the needs of those living with rare diseases.


Raising Awareness Of What It Means To Be Rare

There are over 300 million people worldwide living with a rare disease. Together across borders, and across the 6000+ rare diseases we work towards more equitable access to diagnosis, treatment, care, and social opportunity.

Our key message for Rare Disease Day 2021 is that:

Rare is many.
Rare is strong.
Rare is proud.
