The Blood Center of Wisconsin says donors are urgently needed.
The center provides blood to 56 hospitals in the Badger State -- and it's been getting fewer donations because the flu season is running longer than normal, and heavy snow earlier this month kept people from getting out. As a result, the Blood Center has had less than a one day supply of "O" negative blood for about the past week -- and most other types of blood have had two day supplies for the last month. The center tries to have three day supplies on hand. The Blood Center of Wisconsin is based in Milwaukee, with locations in Manitowoc, Marshfield, and La Crosse as well as the Milwaukee metro.
