Every third Saturday in September, since 2015, World Marrow Donor Day has been celebrated.
Initially, it was celebrated in four European countries, where the activities of the World Association of Bone Marrow Donors were gaining momentum. However, the importance of the problems solved due to the presence of a single register of bone marrow donors, that is, a database of donors who, if necessary and if the genotype matches, are ready to become donors for a patient in need of transplantation, has led to the fact that the action to celebrate the Day of the bone marrow donor has received an international coverage and has been supported in different parts of the Earth. Today, the holiday is celebrated in more than 50 countries around the world.
The World Marrow Donor Association is an alliance of organizations and individuals working on behalf of bone marrow donors and people who need or have had a bone marrow transplant.
