Tennessee Department of Agriculture reports West Nile Virus detected in Middle Tennessee Horse

Tennessee Department of AgricultureNashville, TN – Despite the cooler temperatures, mosquitoes are still active in Tennessee. The state veterinarian is confirming a case of mosquito-borne West Nile virus (WNV) in a horse in Robertson County.

Mosquitoes transmit WNV. Sick horses cannot directly infect humans or other horses.

Vector-borne diseases (such as the Zika virus, which can be spread by aedes aegypti mosquitoes) account for more than 17 percent of all infectious diseases, causing more than 700,000 deaths annually, according to the World Health Organization. (U.S. Centers for Disease Control and Prevention)

Symptoms in horses may include fever, weakness, loss of appetite, or convulsions. The illness can cause lasting effects and, in some cases, can be fatal. The horse in Robertson County did not survive.

“West Nile virus is a devastating, and often deadly, illness for horses,” State Veterinarian Dr. Samantha Beaty said. “However, the vaccine for WNV is highly effective. Appropriate vaccinations will safeguard the health of your horse and prevent a tragic loss.”

Horse owners should work with a veterinarian to determine the best vaccination plan for their livestock, eliminate standing water sources where insects gather and breed, and apply insect repellants as needed. For horses stabled indoors, a breeze from an electric fan makes it difficult for insects to fly.

The C. E. Kord Animal Health Diagnostic Laboratory offers a full line of equine disease testing, including WNV, equine infectious anemia (EIA), equine herpes virus (EHV), equine protozoal myeloencephalitis (EPM), eastern equine encephalitis (EEE), and equine influenza virus (EIV).
