Publicly available genome sequence database for viruses?

There area few different influenza virus database resources:

• The Influenza Research Database (IRD) (a.k.a FluDB - based upon URL)
  • A NIAID Bioinformatics Resource Center or BRC which highly curates the data brought in and integrates it with numerous other relevant data types
• The NCBI Influenza Virus Resource
  • A sub-project of the NCBI with data curated over and above the GenBank data that is part of the NCBI
• The GISAID EpiFlu Database
  • A database of sequences from the Global Initiative on Sharing All Influenza Data. Has unique data from many countries but requires user agree to a data sharing policy.
• The OpenFluDB
  • Former GISAID database that contains some sequence data that GenBank does not have.

For those who also may be interested in other virus databases, there are:

• Virus Pathogen Resource (VIPR)
  • A companion portal to the IRD, which hosts curated and integrated data for most other NIAID A-C virus pathogens including (but not limited to) Ebola, Zika, Dengue, Enterovirus, and Hepatitis C
• LANL HIV database
  • Los Alamos National Laboratory HIV database with HIV data and many useful tools for all virus bioinformatics
• PaVE: Papilloma virus genome database (from quintik comment)
  • NIAID developed and maintained Papilloma virus bioinformatics portal
