  abstract = {{H}ighly pathogenic avian influenza ({HPAI}) {H}5{N}1 virus has been circulating in {V}ietnam since 2003, whilst outbreaks of {HPAI} {H}5{N}6 virus are more recent, having only been reported since 2014. {A}lthough the spatial distribution of {H}5{N}1 outbreaks and risk factors for virus occurrence has been extensively studied, there have been no comparative studies for {H}5{N}6. {D}ata collected through active surveillance of {V}ietnamese live bird markets ({LBM}s) between 2011 and 2015 were used to explore and compare the spatiotemporal distributions of {H}5{N}1- and {H}5{N}6-positive {LBM}s. {C}onditional autoregressive models were developed to quantify spatiotemporal associations between agroecological factors and the two {HPAI} strains using the same set of predictor variables. {U}nlike {H}5{N}1, which exhibited a strong north-south divide, with repeated occurrence in the extreme south of a cluster of high-risk provinces, {H}5{N}6 was homogeneously distributed throughout {V}ietnam. {S}imilarly, different agroecological factors were associated with each strain. {S}ample collection in the months of {J}anuary and {F}ebruary and higher average maximum temperature were associated with higher likelihood of {H}5{N}1-positive market-day status. {T}he likelihood of market days being positive for {H}5{N}6 increased with decreased river density, and with successive {R}ounds of data collection. {T}his study highlights marked differences in spatial patterns and risk factors for {H}5{N}1 and {H}5{N}6 in {V}ietnam, suggesting the need for tailored surveillance and control approaches.},
