There are 100 days of summer and the American Red Cross urges eligible donors to choose their day to give blood and help ensure a sufficient blood supply.Summer is a difficult time to collect enough blood to meet patient needs, a press release from the Red Cross said. Nearly 90% of donors surveyed this past spring said they planned to take a vacation this summer, potentially making them less available to give. In addition, many schools that host blood drives are out of session during the summer. But the need for blood donations is constant. Every two seconds someone in the United States needs blood.Donors of all blood types \u2014 especially those with types O negative, A negative and B negative \u2014 are needed. The Red Cross must collect 15,000 blood donations every day to meet the needs of patients at approximately 2,600 hospitals and transfusion centers nationwide.To make an appointment to give blood, download the Red Cross Blood Donor App, visit redcrossblood.org or call 1-800-RED CROSS (1-800-733-2767).
