Abstract
Although 800,000-2 million persons in the United States have chronic hepatitis B virus (HBV) infection(1), only an estimated two-thirds of them have a diagnosis. We examined the reasons HBV-infected participants in the CheCS had been tested. CheCS is an observational cohort study created to assess the natural history and clinical encounters of chronic viral hepatitis in the United States. Of 3,358 patients aged ≥18 years who met the inclusion criteria for chronic hepatitis B virus (HBV) infection (2), 2,725(81.2%) were sampled randomly for survey. After the exclusion of 450 patients who died or could otherwise not be contacted, the remaining 2,275 (67.7%) patients were surveyed by U.S. mail or telephone.
