Prevalence and Genotype Distribution of Hepatitis C Virus Infection at Zonal Hospital in Northern India

Background: Hepatitis C virus (HCV) infection is a major public health concern. Persons living with HCV infection are at risk of developing liver cirrhosis and progressing to end-stage liver disease and liver cancer (hepatocellular carcinoma). The present study was undertaken to assess the prevalence of HCV infection in patients admitted as well as outpatient department services of a Zonal Hospital. Methods: The present study was cross-sectional, observational study, conducted in patients >18 years of age, clinically suspected acute infectious hepatitis or admitted to the intensive care unit, and willing to participate in the study. Results: In the present study, 472 patients were studied for hepatitis C infection. Majority of cases were from 51 to 60 years age group (34.5%), followed by 61-70 years age group (26.7%). Female cases were (51.3%) slightly more than male (48.7%). Rapid method and enzyme-linked immunosorbent assay (ELISA) methods detected HCV prevalence as 5.7% and 12.5%, respectively. After HCV genotype testing, the prevalence was 12.1%. Majority had 3A genotype (69.49%), followed by 1A genotype (16.95%), 1B genotype (8.47%), 3B genotype (3.39%), and 4 genotypes (1.69%). ELISA testing was significantly correlated with HCV genotype testing (P = 0.017) while the rapid method was not correlated with HCV genotype testing (P = 0.937). Conclusion: There is a high prevalence of HCV among the suspected, genotype 3 being the most common.
