Transfusion With Donated Blood and Risk of HIV Infection
Before the test for HIV was developed in March 1985,
HIV was spread to people who received blood or blood
products donated by HIV-infected people. Since 1985, the risk has been almost
eliminated. Blood banks and health professionals:
Do not accept blood from people who are at risk
for HIV infection.
Screen donated blood for HIV.
Treat certain blood products
to destroy HIV if it is present.
Today, the risk of getting HIV from a transfusion of one unit of
blood is extremely low. This low risk does not decrease the importance of
limiting the use of donated blood or encouraging people who know they are going
to have surgery to donate their own blood (autologous donation).
A variety of HIV risk factors can increase your chances of becoming infected with a virus called HIV (human immunodeficiency virus). This infection can lead to AIDS (acquired immunodeficiency syndrome), which makes it more difficult for your body to fight off infection and disease. Some risk factors increase your HIV risk more than others. You can't entirely eliminate risk, but you can do many things to lower your risk and protect yourself.
