Every year on 14 June, countries around the world celebrate World Blood Donor Day (WBDD). The event, established in 2004, serves to raise awareness of the need for safe blood and blood products, and to thank blood donors for their voluntary, life-saving gifts of blood.
World Blood Donor Day is one of eight official global public health campaigns marked by the World Health Organization (WHO), along with World Health Day, World Tuberculosis Day, World Immunization Week, World Malaria Day, World No Tobacco Day, World Hepatitis Day, and World AIDS Day.
Transfusion of blood and blood products helps and save millions of lives every year. It can help patients who suffering from life-threatening conditions live longer and with higher quality of life, and supports complex medical and surgical procedures.
It also has an essential, life-saving role in maternal and perinatal care. Access to safe and sufficient blood and blood products can help reduce rates of death and disability due to severe bleeding during delivery and after childbirth.
In many countries, there is not an adequate supply of safe blood, and blood services face the challenge of making sufficient blood available, while also ensuring its quality and safety. An adequate supply can only be assured through regular donations by voluntary unpaid blood donors.
The WHO's goal is for all countries to obtain all their blood supplies from voluntary unpaid donors by 2020. In 2014, 60 countries have their national blood supplies based on 99-100% voluntary unpaid blood donations, with 73 countries still largely dependent on family and paid donors.
World Blood Donor Day brings a precious opportunity to all donors to celebrate and commemorate the birthday anniversary of Karl Landsteiner (a scientist who won the Nobel Prize for his discovery of the ABO blood group system).
