"Record-breaking cold and severe winter weather across most of the U.S. has forced the cancellation of American Red Cross blood drives in approximately 30 states — impacting approximately 16,000 blood, platelet and convalescent plasma donations this month," Jessa Merrill, spokesperson for the American Red Cross, said in an emailed statement. "The Red Cross is urging healthy individuals in unaffected areas, especially those with type O blood, to give now."
