Officials say blood donors are urgently needed across Virginia.
Virginia Blood Services says a decline in blood donations around the Fourth of July holiday has caused a nationwide blood shortage. The group is projecting a shortfall of 1,700 donations per week in its service area this month.
Virginia Blood Services says there is currently only a two-day supply of O-negative blood. The group says that's half the ideal supply of the universal blood type, which is especially important this time of year when there are increased accidents and trauma cases.
Officials are also looking for platelet donations, which last on the shelf just five days.
