A preregistered meta-meta-analysis on the global distribution of Hepatotropic Viruses

Abstract

Introduction. Hepatotropic viruses (HAV, HBV, HCV, HDV, and HEV) significantly impact global health, with varying prevalence across regions. Objective. This study aims to systematically consolidate data from diverse meta-analyses to provide a contemporary reference on virus distribution and prevalence. Materials and methods. Adhering to PRISMA guidelines, the study utilized a mixed effects model for data integration. Quality evaluation was carried out with QUOROM and AMSTAR tools, with heterogeneity assessed via the Higgins I2 statistic, Q-statistic and Tau squared (τ2) values. Results. The study analyzed 86 meta-analyses from 56 studies (2017–2022) with minimal overlap. Prevalence rates by region were as follows: MENA – 29.2%, Afghanistan – 9.14%, Africa – 8.10%. Prevalence rates by virus type: HAV – 82.5%, HBV – 8.6%, HCV – 15.1%, HDV – 8.9%, HEV – 13.9%, dual HBV-HCV coinfection – 2.2%. Prevalence rates by risk groups: general population – 8.3%, healthcare workers – 4.0%. Continent-specific HBV-HCV prevalence rates: Africa – 9.2%, China – 6.9%, others. HCVprevalence rates among at-risk groups: healthcare workers – 5.58%, hemodialysis patients – 34.8%. Regional HCV rates: Africa – 7.42%, Middle East – 25.30%. Conclusion. Diverse global hepatotropic virus prevalence patterns are influenced by multifaceted factors. MENA faces higher rates due to healthcare challenges, while Africa struggles with limited resources. Tailored public health strategies, including vaccination and awareness campaigns, are essential to alleviate burdens and enhance global health. This consolidated data serves as a valuable resource for informed decision-making.
