Can I get hepatitis C through blood transfusions in the us?

Extremely unlikely. Our blood supply in the us has multiple mechanisms to reduce the risk of acquiring hepatitis c through transfusion to less than 1 in 1.6 million. However, tens of thousands of people got hepatitis c through blood transfusions prior to 1992 and so anyone who had a transfusion before 1992 should be tested for hepatitis c.
Yes but rare. Since 1992, the us blood supply has been rigorously tested for many infections including hepatitis c. Getting a blood transfusion since then has been pretty safe. Your risk of contracting hepatitis C is not zero but the risk is low.
