The Baltimore index leads to taxonomic listing of virus families and species, linking to viral family pages.

Another way surfing through viewing virus families is to Browse viruses by host where viruses are clustered depending on the infected host. So one can choose to display only Human viruses for example

Viral Family pages
All viral family pages contain a header describing viral specific informations:
-Molecular Biology (Virion and genome picture, gene expression, replication)
-Taxonomic and host informations
-Epidemiology informations (geography, associated diseases, vaccine etc..) UniProtKB/Swiss-Prot entries
The second part of the viral family pages contains a listing of all UniProtKB/Swiss-Prot protein entries for this viral family. The user can sort entries either by protein name, or by species. Species name is black when all the genome encoded proteins are displayed. When only part of the viral proteins are displayed, the species name is in grey.
DB links provides useful access to related web sites:
International Committee on Taxonomy of Viruses (ICTV) database
Nucleotide DB links to NCBI taxonomic pages, from which DDBJ/EMBL/GenBank nucleotides entries can be found.
Protein DB links to UniProtKB list of protein entries:
lists all reviewed entries (Swiss-Prot)
lists all unreviewed entries (TrEMBL)
