Current awareness of chronic viral hepatitis infections in the United States remains suboptimal, according to study results published in the Journal of Viral Hepatitis.
The researchers used the National Health and Nutrition Examination Survey (NHANES) 2013-2016 to determine the current awareness rate of chronic viral hepatitis in the United States. The study included survey participants who underwent serology testing for chronic viral hepatitis (n=11,488). The researchers defined chronic hepatitis B virus (HBV) infection by serum hepatitis B surface antigen (HBsAg), HBV exposure by serum antibody to hepatitis B core antigen (anti-HBc), and hepatitis C virus (HCV) infection by HCV RNA.
The results indicated that 33.9% of participants were aware of their chronic HBV infection, 11.7% were aware of their past HBV exposure, and 55.6% were aware of their HCV infection.
