75% of those with hep C don’t know it.
The U.S. Preventive Services Task Force (USPSTF) recommends screening for hepatitis C virus in persons at high risk for infection and a one-time screening for ALL adults born between 1945 and 1965 (baby boomers).
The most important risk factor for HCV infection is past or current injection drug use, with most studies reporting a prevalence of 50% or more. Many HCV infections are identified only after the patient becomes symptomatic.
