The aim of the study is to
prevalence of different HBV serologies and HCV infection in VAs.
This study was
based on the data collected by testing for Hepatitis B surface
anti-hepatitis B core antibody (HBcAb IgG), anti-HBs antibody
anti-HCV antibody (anti-HCV) in a series of community screening in
Orange County, California.
In 1,405 VA participants, the mean age
