"Blood saves lives" theme of World Health Day 2000 CMAJ 2000;162:1031 Raising global awareness about blood safety and the importance of voluntary donors will be the focus of World Health Day on Apr. 7. In promoting the event, the World Health Organization cites an increasing need for safe blood donations. Worldwide, about 75 million units of blood are collected annually, but only 53% are from voluntary, nonpaid donors. About 18 million units are not tested for transfusion-transmissible infections; WHO says that between 5% and 10% of cases of HIV infection are caused by the transfusion of contaminated blood and blood products. WHO hopes to use the day to encourage governments and policymakers to achieve a safe blood supply (www.who.int/pht/blood_safety).
