West Nile virus in wild resident birds, Southern France, 2004.
An equine West Nile virus (WNV) outbreak occurred in 2004 in the Camargue, a wetland area in the south of France where the virus was first reported in 1962 and re-emerged in 2000. WNV neutralizing antibodies were detected in resident birds and two isolates from a House Sparrow (Passer domesticus) and a Common Magpie (Pica pica) were completely sequenced. Phylogenetic analyses revealed that these isolates are closely related to strains previously found in horses in southern Europe and North Africa. More extensive investigation is required to determine whether WNV has been re-introduced or has become endemic in the Camargue.
