Indications for Testing Among Reported Cases of HCV Infection From Enhanced Hepatitis Surveillance Sites in the United States, 2004–2010

Abstract

Centers for Disease Control and Prevention has recommended a 1-time HCV test for persons born from 1945 through 1965 to supplement current risk-based screening. We examined indications for testing by birth cohort (before 1945, 1945-1965, and after 1965) among persons with past or current HCV. Cases had positive HCV laboratory markers reported by 4 surveillance sites (Colorado, Connecticut, Minnesota, and New York) to health departments from 2004 to 2010. Health department staff abstracted demographics and indications for testing from cases' medical records and compiled this information into a surveillance database. Of 110, 223 cases of past or current HCV infection reported during 2004-2010, 74, 578 (68%) were among persons born during 1945-1965. Testing indications were abstracted for 45, 034 (41%) cases; of these, 29 ,544 (66%) identified at least 1 Centers for Disease Control and Prevention-recommended risk factor as a testing indication. Overall, 74% of reported cases were born from 1945 to 1965 or had an injection drug use history. These data support augmenting the current HCV risk-based screening recommendations by screening adults born from 1945 to 1965.
