Resumen

The transmissibility of viral hepatitis by blood products has been recognized for decades.^{20 Beeson P. Jaundice occurring one to four months after transfusion of blood or plasma JAMA 1943 ; 121 : 1332

A serum antigen (Australia antigen) in Down's syndrome, leukemia, and hepatitis Ann Intern Med 1967 ; 66 : 924-931

In 1989, Choo et al discovered the elusive causative agent, named hepatitis C virus (HCV), using serum isolated from a patient with NANB hepatitis.^{39 Choo Q.-L., Kuo G., Weiner A.J. , y al. Isolation of a cDNA clone derived from a blood-borne non-A, non-B viral hepatitis genome Science 1989 ; 88 : 359-362

An assay for circulating antibodies to a major etiologic virus of human non-A, non-B hepatitis Science 1989 ; 244 : 362-364

This article reviews the prevailing knowledge of the hepatitis C virus, which afflicts millions worldwide in what has been called “the silent epidemic.”
