Hepatitis C screening targets groups with higher prevalence in the population. People over age 40 are a stated at-risk group because older birth cohorts have higher infection rates, often due to exposure to risk factors before modern blood screening and infection-control measures were in place. Since hepatitis C can run silently for years, focusing on this age group helps identify infections that might otherwise go undetected. The other options don’t reflect recognized risk groupings: young children have lower prevalence; alcohol use itself isn’t a risk factor for Hep C; and having Type 1 diabetes isn’t an indicator of higher Hep C risk.
