West Nile Virus Veterinary and Wildlife Information
Following the 1999 West Nile virus outbreak, restrictions were placed on the import of equine from the United States by the European Union, Hong Kong, Argentina, Brazil, and the United Arab. Various restrictions were also implemented on the export of ostrich, poultry, and other potentially effected livestock from the United States.
Currently, WNV has been detected in more than 284 wild and captive bird species. In addition to a widespread disease among birds, WNV also effects equine. Currently, there are two licensed vaccines available to help protect horses from WNV.
WNV has also been detected in free-ranging mammals including the raccoon and certain bat and chipmunk species. Some domestic animals including the cat, dog, chicken, and rabbit have tested positive for WNV. The virus was also detected in black bears and aquarium seal in New Jersey, as well as captive birds at the U.S. National Zoo in Washington DC.
