Hepatitis C virus incidence trend and its risk factors among people who inject drugs in Hai Phong, Vietnam.

ABSTRACT:

Background

HCV incidence among people who inject drugs (PWID) remains unacceptably high. Using the data from the DRIVE study, we aimed to describe HCV incidence trends and investigate its associated risk factors among PWID in Hai Phong, Vietnam.

Methods

Active PWID were recruited through 3 annual respondent-driven sampling (RDS) surveys; part of them were included in the study cohorts. HCV seroincidence was calculated for PWID participating in multiple surveys (recaptures) or in cohorts. A nested case-control design was used for risk factor analysis. Controls were matched to HCV seroconversion cases on age, sex, cohort participation and HCV seroconversion visit. Risk factors were measured over the period preceding the HCV seroconversion visits.

Results

There were 83 H
