Further subdivision of the RNA viruses is based on whether the RNA genome is segmented.
The Baltimore classification of viruses is based on the mechanism of mRNA production.
Most information on transmission of influenza viruses is based on older experimental studies, inference from observations during outbreaks, and studies with other objectives, especially the assessment of vaccine or drug efficacy.
The part dedicated to influenza viruses was based on consensus sequences specific for one gene generated from global alignments of a large number of influenza virus sequences available in databanks.
The criterion used for future identification of the H1N1pdm viruses was based on the detection of BC signatures identical to those of A/California/04/2009 in at least five of the six targets in the "core" genes.
The procedures used for the collection of viruses were based on previous studies with some modifications.
