Blood transfusion? Hep B Or Hep C?

Most common disease or infection transmitted by blood transfusion??
Hep B Or Hep C?

Hepatitis C virus (HCV) is mostly transmitted through exposure to infective blood. This may happen through transfusions of HCV-contaminated blood and blood products, contaminated injections during medical procedures, and through injection drug use. Sexual transmission is also possible, but is much less common.
