Core Tip
Core tip: Hepatitis B virus (HBV) eradication could be achieved through three important points: (1) efficient universal vaccination; (2) accurate diagnostic assays; and (3) effective treatment of HBV carriers. Undoubtedly, these critical measures are not possible without fully understanding the genetics of the virus and being able to differentiate the isolates. In this review article we provide an update of HBV virology, focusing on classification and its impact on diagnosis, clinical outcomes, therapy, prophylaxis, evolution and epidemiology. Subsequently, the role of correct classification in describing HBV is highlighted, and misclassifications together with their causes are recounted. Finally, through the proposal of novel terms, HBV strains are reclassified.
