Technological advancements in phylodynamic modeling coupled with the accessibility of real-time pathogen genetic data are increasingly important for understanding the infectious disease transmission *** this study,we compare the transmission potentials of North American influenza A(H1N1)pdm09 derived from sequence data to that derived from surveillance *** impact of the choice of tree-priors,informative epidemiological priors,and evolutionary parameters on the transmission potential estimation is *** American Influenza A(H1N1)pdm09 hemagglutinin(HA)gene sequences are analyzed using the coalescent and birth-death tree prior models to estimate the basic reproduction number(R_(0)).Epidemiological priors gathered from published literature are used to simulate the birth-death skyline ***-sampling marginal likelihood estimation is conducted to assess model fit.A bibliographic search to gather surveillancebased R_(0)values were consistently lower(mean≤1.2)when estimated by coalescent models than by the birth-death models with informative priors on the duration of infectiousness(mean≥1.3 to≤2.88 days).The user-defined informative priors for use in the birth-death model shift the directionality of epidemiological and evolutionary parameters compared to non-informative *** there was no certain impact of clock rate and tree height on the R_(0)estimation,an opposite relationship was observed between coalescent and birth-death tree *** was no significant difference(p=0.46)between the birth-death model and surveillance R0 *** study concludes that treeprior methodological differences may have a substantial impact on the transmission potential estimation as well as the evolutionary *** study also reports a consensus between the sequence-based R_(0)estimation and surveillanceased R_(0)***,these outcomes shed light on the potential role of phylodynamic modeling to augment existing surveillance
