Around the world, more than 112 million units of blood are needed every year. Because blood and blood components are perishable, the supply must be replenished regularly by donors in the community where they are needed. Every two seconds, someone in the United States needs blood. The biggest blood shortages in the United States occur in December and January after the holidays, and in June and July over the summer.
