What is transfusion-transmitted infection?

Transfusion-transmitted infection refers to the transmission of infectious agents such as viruses, bacteria, and parasites through blood transfusions. Transfusion-transmitted infections can occur when the blood of a donor, who may be asymptomatic or undiagnosed with an infection, is transfused into a recipient. The most common transfusion-transmitted infections include hepatitis B and C, human immunodeficiency virus (HIV), and West Nile virus. The risk of transfusion-transmitted infection can be reduced by careful screening of donors and the use of advanced testing methods to detect infectious agents in donated blood.
