The Wisconsin Department of Agriculture, Trade, and Consumer Protection has confirmed a case of Eastern Equine Encephalitis in Marathon County. An unvaccinated 17-year-old Appaloosa cross mare went down on 10/20/17. The attending veterinarian saw the mare on 10/20/2017. He reported that she had been high-stepping and star-gazing prior to recumbency. In recumbency, he reported that she was twitching and acting delirious. The veterinarian sampled and treated her with anti-inflammatories and steroids; he said she got up and was showing neurologic signs, but is recovering. This is the 24th case of EEE reported in Wisconsin in 2017.
