Office of the Delaware State Veterinarian

The Office of the Delaware State Veterinarian has confirmed one case of West Nile Virus in Kent County. A 6-year-old, unvaccinated Belgian mare displayed neurological clinical signs from October 12-18, 2018. Diagnostic testing at the National Veterinary Services Laboratory confirmed WNV on 10/23/18. The mare displayed whole body stiffness (acting sore), and abnormal mentation, described as extreme aggression towards the reporting veterinarian during handling. The aggression was atypical for this animal, which is normally very gentle. When first seen on 10/14/18, the horse was afebrile, was not ataxic, was not weak or wobbly, and was lacking notable muscle fasciculations. With 3-4 days of anti-inflammatory treatment, the horse improved markedly and was back to normal by 10/18/18.
