Because of abnormal and recurrent field mortality, wild migratory birds were considered to be the main dispersing agent of the virus at an intercontinental scale. European wintering wetlands, such as the Camargue (Rhone delta, France), are identified as potential hot spots for the risk of introduction and transmission of bird-borne diseases. In this study, we investigated the role of migratory waterbirds (mainly ducks) in the spread of HP 145N1 viruses. We combined molecular analysis of living and freshly killed birds with population surveillance (aerial censuses and death surveillance). We sampled 1345 birds belonging to 17 waterbird species Q orders) in the Camargue between September 2005 and March 2006. The prevalence of ATV was 1.8%. We did not detect HP H5N1 virus. Population censuses did not reveal any population decreases nor abnormal mortalities. We discuss, in the light of these results, the implication of wild migratory ducks in the arrival of HP H5N1 AIV in Europe. specialized avian influenza anseriforms Camargue 052 7 5 604-608 2007 1567-1348 https://www.documentation.ird.fr/hor/PAR00002008 10.1016/j.meegid.2007.05.009 1567-1348 [F B010040807] https://www.documentation.ird.fr/hor/PAR00002008 https://www.documentation.ird.fr/intranet/publi/2007/11/010040807.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2007-12-03 2017-08-23 PAR00002008 fre
