Rock River Valley Blood Center says blood supply in bad shape

ROCKFORD, Ill. (WIFR) -- The Rock River Valley Blood Center says its supply of blood would not even last one day.

The center says supplies for A-negative, O-negative, B-negative and B-positive are very low. The extreme cold, the peak of cold and flu season plus holiday travel are being blamed for the low numbers and putting donor traffic almost at a standstill.

A similar shortage is being felt at blood centers across the country. The American Red Cross says it is in critical need of O-negative and B-negative blood.

To donate, you must be in good health and at least 17 years old, or 16 years old with parental consent. Donors should also weight at least 110 pounds.
