Continental synchronicity of human influenza virus epidemics despite climactic variation

PLoS Pathog
PMCID: 5764404
PMID: 29324895
DOI: 10.1371/journal.ppat.1006780

[…] the presence of Australia-specific clades, we estimated the phylogenetic relationships of influenza virus A and B on a global scale. For this we utilized global gene sequence data available from the GISAID EpiFlu database ( [, ] (note that these data are unlinked to the influenza incidence data analyzed here). All available HA genetic sequences, with a minimum length of 500 nu […]


Swarm incursions of reassortants of highly pathogenic avian influenza virus strains H5N8 and H5N5, clade, Germany, winter 2016/17

Sci Rep
PMCID: 5758748
PMID: 29311555

[…] oftware suite (v.10.0.9; Biomatters, Auckland, New Zealand). Phylogenetic analyses of sequences were done using RAxML, and SplitsTree4 was used for network analyses. Sequences were deposited into the GISAID EpiFlu™ database. A detailed list and acknowledgement of the sequences retrieved from EpiFlu™ database is given in Supplementary Table . […]


Stability of the Influenza Virus Hemagglutinin Protein Correlates with Evolutionary Dynamics

PMCID: 5750392
PMID: 29299534
DOI: 10.1128/mSphereDirect.00554-17

[…] Nucleotide sequences for the influenza virus hemagglutinin (HA) coding region were obtained from the Global Initiative on Sharing All Influenza Data (GISAID) EpiFlu database ( Full-length protein-coding sequences were selected for all A/H1N1pdm09 samples collected from humans from 12 March 2009 (the first recorded A/H1N1pdm09 v […]


Parallel evolution of influenza across multiple spatiotemporal scales

PMCID: 5487208
PMID: 28653624
DOI: 10.7554/eLife.26875.027

[…] patient in our study, we determined the viral consensus sequence at the first sequenced time point. We also downloaded the set of 503 sequences in the Global Initiative on Sharing All Influenza Data (GISAID) EpiFlu database () corresponding to all full-length HA coding regions from human H3N2 influenza A isolates collected in the USA from January 1, 2004 to December 31, 2007 (GISAID acknowledgemen […]


Trivalent inactivated influenza vaccine effective against influenza A(H3N2) variant viruses in children during the 2014/15 season, Japan

PMCID: 5291153
PMID: 27784529
DOI: 10.2807/1560-7917.ES.2016.21.42.30377

[…] he neighbour-joining method []. The viruses were isolated in the 2014/15 influenza seasons. The nucleotide sequences determined are available from the Global Initiative on Sharing All Influenza Data (GISAID) EpiFlu database. Accession numbers for the HA genes are EPI679784-EPI679834, respectively (). […]


Molecular Epidemiology and Spatio Temporal Dynamics of the H3N8 Equine Influenza Virus in South America

PMCID: 5198161
PMID: 27754468
DOI: 10.3390/pathogens5040061

[…] of BioEdit, along with 144 reference HA complete sequences (complete HA data set) available at the Influenza Research database (IRD) up to January 2015 and one sequence from Brazil obtained from the GISAID EpiFlu™ Database. In addition, a partial HA1 nucleotide sequence (from position 52 to 545) from a strain detected in Chile in 2012 available at the IRD, was also analyzed in the partial HA1 dat […]
