The American Red Cross says it has an urgent need for blood donors amid a blood shortage, due in part to fewer blood drives during the July Fourth holiday week.
The Red Cross said Tuesday it had less than a three-day supply of most blood types.
Hundreds fewer blood drives were held during the week of July Fourth than in a normal week, the Red Cross said.
The lack of blood drives compounded a shortfall of more than 24,000 blood donations in June.
