Without every single blood donation of approximately 3.8 million people who donate blood at the Red Cross, this supply would be impossible. The German Red Cross needed daily 15,000 blood donations. It is therefore important that especially young people as new and regular blood donors are won. But not only in Germany attention will be paid the blood and all blood donors on June 14, but around the world. So, in addition to the International Federation of Red Cross and Red Crescent Societies (IFRC), the World Health Organization (WHO) and the international society for transfusion medicine (ISBT), engaged the International Federation of blood donation organizations (FIODS) on this day and points to the importance of blood donation.
