Accessible Version:  Using Evolution to Understand Influenza

Full Virus Database: Researchers can retrieve both genetic and protein sequences from different viruses using the searchable Viroinformatics database. Categories that researchers can specify include the name of the virus, the host, a specific gene, and the type of virus.

For example, a search for sequences in the influenza virus, human host, hemagglutinin gene, type A found 17,387 sequences; for type B, 2,945 sequences; and for type C, no sequences. Type C influenza viruses are not found in the Viroinfomatics database because they cause only mild health problems in humans. Type C virus genome sequences can be found in the public GenBank database.
