该数据库是一个基于WWW的数据库肝炎病毒数据库（HVDB），包含INSDC提供的所有HCV、HBV和HEV序列。在HVDB中，从INSDC获得的所有片段序列被排列到每个病毒的基因组序列。数据库中还提供了每种病毒变异株之间基因组上每个基因座的系统发育关系。

The database is a WWW-based database hepatitis virus database (HVDB), which contains all the HCV, HBV, and HEV sequences available at INSDC. In the HVDB, all piece sequences obtained from INSDC are arranged to the genomesequence of each virus. Also given in the database are the phylogenetic relationships of each locus on the genome among variants for each virus.
