Hepatitis C virus (HCV) has become the most significant cause of chron
ic liver disease of infectious etiology in the United States. The reco
gnition that HCV can be transmitted perinatally or through blood trans
fusions warrants particular attention by the pediatrician. The America
n Academy of Pediatrics recommends screening infants born to HCV-infec
ted mothers and persons with risk factors for HCV infection such as in
jection drug use, transfusion of greater than or equal to 1 U of blood
or blood products before 1992, or hemodialysis should be screened for
anti-HCV. Also, persons who received clotting factor concentrates bef
ore 1987, when effective inactivation procedures were introduced, also
should be screened. Guidelines for counseling families of HCV-infecte
d children are provided.
