An emergency blood shortage has been declared by the American Red Cross due to a significant drop in the national blood supply. The supply fell nearly 25% in June, following a decline in donations after Memorial Day. Hospitals are experiencing increased demand for blood during the summer trauma season, which is exacerbating the shortage.

The Red Cross is distributing more units of blood to hospitals than expected, but the organization is urging eligible donors to give blood to help meet the need. Further details about the shortage and how to donate are available from the American Red Cross.
