Abstract excerpt

The first influenza pandemic of this century was declared in April of 2009, with the emergence of a novel H1N1 influenza A virus strain (H1N1pdm). Understanding the evolution of H1N1pdm strains within the South American region is essential for studying global diversification, emergence and resistance, as well as determining vaccine efficacy. In order to gain insight into these matters, phylogenetic analysis was...
