PHILADELPHIA (CBS) — The Red Cross is sounding the alarm about the nation’s blood supply, saying it’s dangerously low. Surging COVID-19 cases, severe weather, declines in donor turnout, canceled blood drives and staffing issues are all contributing to the shortage.

Plus, donated blood has a short shelf-life and supplies must be constantly replenished.

Centers across the country are reporting less than one day’s supply of certain types of blood.
