Abstract

The World Health Organization estimates that 170 million persons are infected with HCV worldwide, but only 22 million are from the Americas and Europe, compared to 94 million from Asia. HCV prevalence in the general US population is 1.6 %, but data for Asian Americans are limited. Our goal was to examine HCV prevalence in Asian Americans in a large ethnically diverse patient cohort seeking primary care at a free clinic in Northern California. A total of 1347 consecutive patients were seen from September 2009 to October 2012 and were studied via individual chart review using case report forms. HCV infection was defined as positive HCV antibody (anti-HCV) or HCV RNA by PCR. 699 out of 1347 patients were screened for HCV. Asian Americans comprised 57.2 % of these patients and 29 (4.1 %) patients tested positive for HCV. Of these 29 HCV-positive patients, 22 (75.9 %) were Asian, yielding a prevalence of 5.5 % for Asians and 2.3 % for non-Asians (P = 0.038). The highest HCV prevalence was seen in Vietnamese patients at 7.9 %, and 6.0 % in Chinese patients. Of the HCV-positive Asians, none had a history of intravenous drug use (IVDU), tattoos, or sexual exposure. On multivariate analysis, significant independent predictors for positi...Continue Reading
