Is the blood supply safe in the United States?
The nation’s blood supply is safer today than it has ever been and is as safe as modern science and medicine can make it. A person cannot contract the virus that causes AIDS by donating blood. In fact, the risks of contracting a bloodborne disease through transfusion pale in comparison to the risks of not receiving a transfusion. The chance of contracting the virus that causes AIDS through a blood transfusion is 1 in 676,000 units of blood.
