 The first Rare Disease Day was coordinated by the European Organisation for Rare Diseases (EURORDIS) and held on February 29, 2008 in numerous European nations and in Canada through the Canadian Organization for Rare Disorders.The date was chosen because February 29 is a "rare day," and 2008 was the 25th anniversary of the passing of the Orphan Drug Act in the United States.Individuals observing Rare Disease Day took part in walks and press conferences to raise public awareness of rare diseases, organized fundraisers, and wrote en masse to government representatives; health-related non-profit organizations across numerous countries also held events, gatherings, and campaigns.
