1. A method for producing a sustained reduction in the viral load of Hepatitis C virus (HCV) in blood from a patient undergoing hemodialysis comprising:

  • (a) identifying a patient infected with HCV in need of hemodialysis;

    (b) removing blood from said patient;

    (c) transferring said blood or a portion thereof to a lectin affinity device comprising;

    (i) a processing chamber configured to receive said blood or portion thereof, said chamber having lectin disposed therein such that said lectin binds HCV viral particles in said blood or portion thereof, and wherein said device is configured to retain said lectin and bound HCV viral particles in said chamber, and(ii) a porous membrane configured to permit passage of viral particles through the pores of said membrane such that said viral particles contact said lectin and said membrane excludes substantially all blood cells from passing through said pores, such that said blood cells do not contact said lectin,wherein said transferring further comprises transferring said blood or portion thereof to said chamber such that said HCV viral particles contact said lectin and are bound thereto;

    (d) removing said blood or portion thereof from said chamber, and(e) returning said blood or portion thereof to said patient.
