Deschutes County horse diagnosed with West Nile Virus

A horse in Deschutes County has tested positive for West Nile Virus – the first equine case in Oregon this year.

Last year, Oregon recorded six cases of West Nile Virus in horses.

The affected horse is a 14-year-old mare with no history of vaccination for the virus. It is under veterinary care and is responding to treatment, according to the Oregon Department of Agriculture.

“Horses become infected with the virus the same way humans become infected, by being bitten by infected mosquitoes,” State Veterinarian Brad LeaMaster said in a statement.

The Oregon Health Authority works with mosquito control agencies and local county health departments to test mosquitoes for West Nile Virus. To date, positive mosquito pools have been detected in Baker, Union, Umatilla, Morrow and Lane counties.

West Nile Virus causes encephalitis and affects the central nervous system. One of the most common signs of West Nile Virus in horses is weakness or uncoordination in the hindquarters. Horse owners who suspect West Nile Virus infection should contact their veterinarian immediately.
Along with vaccination, horse owners can protect their animals by controlling mosquitoes and mosquito breeding areas. Approved repellents can also provide temporary protection.
