Important Update

In Fall 2024, NCBI plans to redirect the Influenza Virus Resource to NCBI Virus, possibly as soon as September. We are working to replicate the highly-used features from this resource prior to the redirection. For most up-to-date and accurate virus data, see NCBI Virus

This tool is used to obtain nucleotide sequences from the database ordered by genome segments for each virus.

By default, it only gets viruses with a complete set of segments in full-length. To get all viruses with any number of sequences, check the radio button next to "All" in the "Show results" box.
