The current global blood shortage of approximately 40 million units every year, focused primarily in developing countries, is making these conditions difficult to address. More than half of the 108 million blood donations collected worldwide every year come from developed countries where only 18 percent of the world's population lives, leaving 82 percent of the world with a lack of blood they may need for various medical treatments.
