Treatment and curability: The goal of treatment is reducing the risk of complications (cirrhosis and HCC). Although HB vaccination can prevent clinical infections (hepatitis), it cannot prevent 100% of subclinical infections. Hepatitis B (HB) vaccination is recommended for all children and adolescents, and all unvaccinated adults at risk for HBV infection (sexually active individuals such as MSM, individuals with occupational risk, and immunosuppressed individuals). Transmission and protection: The most common sources of HBV infection are body fluids. Although chronic hepatitis B develops slowly, HIV/HBV coinfected individuals show more rapid progression to cirrhosis and HCC. Sodium taurocholate cotransporting polypeptide was identified in 2012 as the entry receptor of HBV. Molecular mechanisms of infection, pathology, and symptomatology: HBV replication begins with entry into the hepatocyte. The prevalence of HBV genotype A is significantly higher among men who have sex with men (MSM), compared with the rest of the population. The prevalence of chronic HBV infection in human immunodeficiency virus (HIV)-infected individuals is 5%-15% HIV/HBV coinfected individuals have a higher level of HBV replication, with higher rates of chronicity, reactivation, occult infection, and HCC than individuals with HBV only. Microbial Cell 3(9): 419-436.Įpidemiology, incidence and prevalence: About 5% of the world’s population has chronic hepatitis B virus (HBV) infection, and nearly 25% of carriers develop chronic hepatitis, cirrhosis, and hepatocellular carcinoma (HCC).
