Today is World Blood Donor Day. In Belarus, a unified database of people who participate in blood transfusion is being created. The list includes about 100 000 volunteers. About 20% of these people are under 30. Blood can be donated up to 5 times a year. After the donation procedure, all donors receive a portion of nutrients to restore the body and can to take a day off. The goal of the World Health Organization for all countries is to obtain all their blood supplies from voluntary unpaid donors by 2030.
