summary. To evaluate the prevalence and indicators of hepatitis C virus (HCV) infection in Houston and determine the effectiveness of targeted HCV screening in sexually transmitted disease (STD) clinics. We performed a cross‐sectional survey in low‐risk and high‐risk groups in Houston. This included a blinded survey of HCV conducted in 1010 STD clinic clients having serological syphilis tests, and 1885 multi‐speciality group practice patients having metabolic blood work. This was followed with a targeted hepatitis C survey of 822 high‐risk clients from STD clinics. The seroprevalence of hepatitis C infection in the blinded survey was 3.9% (95% CI 3.0–4.8) in the multi‐speciality group and 5.0% (95% CI 3.7–6.3) in the STD clinics. Prevalence of hepatitis C infection among targeted STD clinic clients was significantly higher at 15.3% (95% CI 12.7–17.7). Risk factors that correlated with HCV infection after logistic regression included: injection drug use (OR = 10, 95% CI = 3.4–30.3), heroin use (OR = 6.6, 95% CI = 2.2–20.5), non‐transfusion/ transplantation blood exposure (OR = 3.0, 95% CI = 1.3–6.9), sharing equipment to snort drugs (OR = 2.5, 95% CI 1.2–5.4), and age above 25 years (OR = 51, 95% CI = 9–47). This study demonstrates that targeting clients in STD clinics for known risk behaviours is an effective way to identify cases of HCV infection. STD clinics allow access to clients with both drug use and sexual risk behaviours and are a useful location for targeting hepatitis C screening and prevention efforts.
