The Department of Agriculture announced today that a second Delaware horse has tested positive for West Nile Virus, but has recovered.
The two-year-old filly from Sussex County is the state’s second confirmed case of West Nile Virus since 2003, said Delaware State Veterinarian Dr. Heather Hirst, who heads the Department of Agriculture’s Poultry and Animal Health Section. Delaware’s first equine case of West Nile Virus this year was diagnosed in Kent County in August; that horse has also recovered.
Unvaccinated horses are at greatest risk of developing clinical signs from both West Nile Virus (WNV) and Eastern Equine Encephalitis (EEE), which are spread by mosquitoes and can be fatal. The department is urging equine owners to vaccinate their horses against West Nile and other mosquito-borne diseases, such as Eastern Equine Encephalitis. EEE was recently detected in a sentinel chicken flock in Sussex County.
