DNREC’s Division of Fish & Wildlife asks public to report sick or dead wild birds for West Nile virus monitoring

The Office of the State Veterinarian announced today Delaware’s fourth and fifth cases of West Nile Virus (WNV) found in horses in 2018. Three previous cases of WNV in horses were reported in 2018, two in August and one in September. Even though we are nearing the end of the mosquito season, the State Veterinarian urges horse owners to contact their veterinarians as soon as possible to have horses and other equines vaccinated against WNV and EEE. Neither disease has a specific drug treatment, and EEE infections in horses are fatal in 70 to 90 percent of cases, and WNV in 30 percent of cases.
The Office of the State Veterinarian announced today Delaware’s third case of West Nile Virus (WNV) found in horses in 2018.

Samples were submitted to the National Veterinary Services Laboratory, which confirmed the diagnosis of WNV on September 7. The vaccination history for this pony is unknown.
