We evaluated the ability of the commercial Sentosa SQ Hepatitis C Virus Genotyping Assay to identify the HCV genotype subtype in patients from The Gambia. Subtype was determined from the Sentosa-generated NS5B sequences using 3 bioanalytical methods: the Sentosa SQ HCV Genotyping Assay bioanalytical tool, Geno2pheno, and the National Reference Center in-house method. The Sentosa assay result agreed with the reference method in only 2 of 13 cases. This study highlights the difficulty of correctly identifying HCV subtypes in a region of Africa with a high diversity of HCV genotype 1 and 2 subtypes that may be resistant to antivirals.

Background: Hepatitis C virus (HCV) and injection drug use among young women are dramatically rising in the rural United States. From 2004 to 2017, heroin use among non-pregnant women increased 22.4% biennially, mirroring increases in HCV cases, especially among younger populations.

Accurate timing estimates of when participants acquire HIV in HIV prevention trials are necessary for determining antibody levels at acquisition. The Antibody-Mediated Prevention (AMP) Studies showed that a passively administered broadly neutralizing antibody can prevent the acquisition of HIV from a neutralization-sensitive virus. We developed a pipeline for estimating the date of detectable HIV acquisition (DDA) in AMP Study participants using diagnostic and viral sequence data.

Discontinuing antivirals in chronic hepatitis B virus (HBV) 'e' antigen negative infection can enhance HBV surface antigen (HBsAg) loss but risks complications. We modelled the clinical impact of discontinuing antivirals in chronic HBV. We developed a Markov state model with Monte Carlo simulation of chronic HBV to compare continuation of antiviral therapy with 3 strategies of cessation and reinitiation for: (1) virologic relapse, (2) clinical relapse, or (3) hepatitis flare.

Hepatitis B virus (HBV) infection is a global health challenge, with the World Health Organization (WHO) targeting its elimination by 2030. Jordan lacks sufficient data on HBV epidemiology, including prevalence, incidence and clearance. This study addresses these gaps through a retrospective analysis of HBV testing data from 40,268 individuals collected at Biolab Diagnostic Laboratories (2010-2024).
