NORTH TEXAS (CBSDFW.COM/AP) — The American Red Cross says there’s an urgent need for people to donate blood following the Fourth of July holiday.

Red Cross officials say the organization is facing an emergency blood shortage because donations lagged during the holiday week, with more than 550 fewer blood drives organized than during a typical week.

The organization is seeking donors of all types, especially type O, which is the most in-demand blood type and the one that’s often depleted from hospital supplies in a shortage.
