Less than before.: This is probably a lot less common than before due to vaccination for hepatitis b, and more diligent screening. The transmission of hepatitis c via transfusion is currently at a rate of about 1 in 2 million units. Hepatitis b is probably less than that.

According to Pathology Outlines.com, due to serologic testing, risk of transfusion transmitted HBV is now 1:205,000 among repeat donors, and 1:144,000 among all donors in the US as of October 2011. So I see it is higher than Hepatitis C, but a lot less than earlier days.

Very Unlikely: Our blood supply has been carefully screening fro hepatitis c since 1992, and HIV and hepatitis b before that. It is extremely unlikely that anyone will develop an infection from these viruses after blood transfusion in the us.

Both B & C: However, the risk of transmission from a blood transfusion with hepatitis b and c is about 1 in 400, 000 and 1 in 2, 000, 000, respectively. All blood now is tested for the antigen or antibody. Very rare. Hope this helps.
