Abstract. To identify areas endemic for hepatitis C virus (HCV), we attempted to predict the prevalence of antibody to HCV (anti-HCV) in a community by the prevalence of elevated levels of alanine aminotransferase (ALT). The results of health examinations of 2,273 women Ն 40 years old in five townships in central Taiwan were analyzed. The overall prevalence of elevated ALT levels was 11.6%. A township (20.3%) and 10 villages were identified as having a high prevalence (17.9−40.0%) of elevated ALT levels. Five communities with variant rates of elevated ALT levels, which ranged from 8.0% to 27.3%, were selected for correlation with the prevalence of anti-HCV among adults (Ն 40 years old). The prevalence of anti-HCV, which ranged from 10.1% to 72.1%, were obtained by community screenings and/or hospital-based studies. The correlation equation used was the prevalence of anti-HCV (%) ס 3.33 × (prevalence of elevated ALT levels (%) -5.7%) (r 2 ס 0.94, P < 0.01). Using this method, areas endemic for HCV can be identified by determining the community prevalence of elevated ALT levels.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
