Background: Hepatitis C virus (HCV) infection is considered one of the growing public health problems. Identification of HCV-associated risk factors is pivotal for developing appropriate prevention strategies. Objectives: To determine the epidemiological variables of HCV infection in a tertiary care hospital. Methods: This hospital-based case-control study was conducted in a tertiary care hospital in Punjab on 320 subjects, including 160 cases and controls each. Cases and controls were matched by age (±5 years), gender, and residence. A patient ≥18 years of age fulfilling the biomarker criteria with or without clinical criteria diagnosed in the last 1 month was considered as a case. The information on socio-demographic characteristics and previous exposures to selected risk factors was collected through detailed interviews of the subjects. Analysis was performed using SPSS 20 statistical software. Odds ratio (OR) with 95% confidence interval (CI) was calculated to measure the strength of association between cases and controls for each risk factor. Results: Odds of having HCV infection was significantly higher among those with a history of blood transfusion (OR: 2.30, 95%CI: 1.14–4.63), dental procedure (OR: 4.82, 95%CI: 2.38–9.77) and intravenous injection/infusion from quacks (OR: 3.26, 95%CI: 1.47–7.19), injectable drug use (OR: 26.69, 95%CI: 3.55–200.24), non-injectable drug use (OR: 2.37, 95%CI: 1.44–3.90), tattooing (OR: 7.91, 95%CI: 2.31–27.08), and piercing from street hawkers (OR: 2.25, 95%CI: 1.18–4.29). Multivariate analysis identified history of blood transfusion, dental procedure, intravenous injection/infusion from quacks, injecting drug use, and piercing as independent risk factors for HCV infection. Conclusion: The study identified multiple risk factors for acquiring HCV infection and suggest appropriate interventions targeting high-risk populations.
