That’s well below the seven-day supply needed by area hospitals.

“This is something happening nationwide. The number of donations are down. And the good news is when we ask the good folks of Delmarva, who live in the state of Delaware and surrounding areas, they tend to respond. It’s not something we take lightly but when it gets to this point, we have to ask for help,” said Tony Prado.
