Every two seconds someone in the U.S. needs blood. To help meet the constant demand for lifesaving blood donations and prevent blood shortages this winter, the American Red Cross is urging individuals and organizations to host a blood drive.  Right now, the Red Cross needs about 6,500 additional groups across the country to host blood drives in December, January and February. In the Carolinas Blood Services Region, about 350 more blood drive hosts are needed. During the winter, there is often a decrease in the number of blood drives, which can contribute to blood shortages.
