No. Donor blood will stay in your system for only about 4 months, coz the life duration of an erythrocyte or red blood cell is only 120 days, when it will be degraded in the spleen. Your body produces red blood cells constantly from the bone marrow every single day, so the donor blood will constantly be diluted until the donor cells die after 4 months. When you receive a blood transfusion, it is merely to tide you over that critical period, because at that time, your body has lost too much blood and exceeded the limit to which it can reproduce the amount of blood lost.
Hope this helps. :D

no the blood does not stay forever. Red blood cells, the cells that carry oxygen, have a life span of 120 days. so your body is continually creating new red blood cells as your old red blood cells continually get old and degrade. so the red blood cells from a transfusion couldn't last any longer than 120 days.

No, it will degrade and die and be replaced like all the other blood in your body.
The lasting things are the viruses because they replicate themselves in other cells and keep going.
