# Seroprevalence of Hepatitis C Virus Among Blood Donors in a Tribal-Preponderant Region of India

## TL;DR

This study examines the spread of Hepatitis C among blood donors in a tribal region of India and finds a higher prevalence linked to male replacement donors.

## Contribution

The study provides updated seroprevalence data for HCV in a tribal-preponderant region of India over nine years.

## Key findings

- The overall HCV seroprevalence was 0.63% among blood donors in Jharkhand.
- All HCV-positive cases were found in male donors.
- Replacement donors contributed the majority of blood donations in the region.

## Abstract

Introduction: Hepatitis C is a global health burden with significant morbidity and mortality. It primarily affects the liver and causes acute hepatitis, chronic hepatitis, liver cirrhosis, and hepatocellular carcinoma. Common modes of transmission of hepatitis C virus (HCV) infection are blood transfusion, needlestick injury, and mother-fetus transmission, among which transmission, blood transfusion is one of the most important causes. Blood transfusion is one of the pillars in the management of patients that saves lives and improves morbidity. Blood donation in India is done by voluntary and replacement blood donors of both sexes. The aim of this study is to determine the seroprevalence of HCV among blood donors in the Jharkhand state, a tribal-preponderant region of India, and to see the trend over the years.

Material and methods: This is a nine-year retrospective observational study from 2015 to 2023 that screened for anti-HCV antibodies (third-generation kit: Abbott Diagnostics) using the chemiluminescence technique.

Results: In this study, in total, 249,461 units of blood were collected, of which the majority of donations were by male and replacement donors (RDs) comprising 230,757 (92.50%) and 188,047 (75.38%), respectively. The mean number of blood donations by replacement and male donors (MDs) was more than for voluntary donors (VDs) and female donors (FDs) (20894.11 ± 3041.71 RDs vs. 6823.77 ± 2332.96 VDs, p < 0.0001 and 25639.66 ± 2810.08 MDs vs. 2078.22 ± 828.16 FD, p < 0.0001), respectively. The overall prevalence of HCV was 0.63%, and all seropositive donors were male.

Conclusion: Replacement blood donation contributes to the major part of blood donation and is primarily done by males in this tribal population-dominant region of India. Seroprevalence of HCV is high in the population of this part of India, and there is a constant or slightly upward trend in hepatitis C infection among individuals.
