Simplified taxonomy of main viruses infecting humans

The diagram below displays a simplified classification scheme of the main viruses commonly associated with human diseases, based on International Committee on Taxonomy of Viruses Database (ICTVdB) and other sources.
Viral family names end with "viridae", sub-family with "virinae" and genus with "virus". Mononegavirales and Nidovirales represent two viral orders regrouping viral families.
In the diagram, viruses with single-stranded DNA genome are indicated as ss DNA and those with single-stranded RNA, as ss RNA. Viruses with double-stranded DNA genome are indicated as ds DNA and those with double-stranded RNA, as ds RNA.
During the replication cycle, viruses that belong to the Hepadnaviridae family have their DNA genome transcribed into RNA, then reverse-transcribed into DNA (DNA→RNA→DNA). Viruses from the Retroviridae family have their RNA genome reverse-transcribed into DNA, then transcribed into RNA (RNA→DNA→RNA).
Please note that some of the viruses listed below are naturally found in animal species but can occasionally infect humans as well (zoonoses).

Use the diagram to facilitate your search in the database and identify viruses according to their taxonomic status.
