écologie des virus influenza aviaires en Camargue - IRD

Émergence du virus H5N1 hautement pathogèneHost structure (e.g. density, inter­ and intra­species genetic diversity) differconsiderably between wild and domestic birds and is likely to be the maindeterminant of virulence selection.Virus fitness is highly dependent on host survival and dispersion in nature, and it isthus unlikely that virulent forms will persist in wild populations if they kill quickly,increase predation risk or compromise migratory performance.Prediction and control of AIV emergence urgently need to consider host ecology andecosystem characteristics (natural or linked with human activities) in which theseviruses evolve.Competing interestsThe authors declare that they have no competing interests.Authors' contributionsCL reviewed the literature and drafted the manuscript.
