DNREC’s Mosquito Control Section within the Division of Fish & Wildlife is scheduled to begin its annual spring woodland pool spraying on Tuesday, March 19.
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 recent detection of Eastern Equine Encephalitis (EEE) in sentinel chickens monitored for mosquito-borne diseases by the DNREC Division of Fish & Wildlife’s Mosquito Control Section reinforces the fact that mosquitoes remain active and that precautions should continue to be taken to avoid mosquitoes whose bites could transmit EEE and other mosquito-borne diseases.
The Office of the State Veterinarian announced today Delaware’s third case of West Nile Virus (WNV) found in horses in 2018. The infected equine is a 10-year-old pony gelding that was purchased from a Pennsylvania livestock auction and transported to a premises in New Castle County, DE on August 27. On August 30, the pony was observed to have a fever, was leaning and walking sideways. He progressed to show signs of wobbling and staggering, decreased tail tone, and facial nerve deficits. 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.
DPH Officials Concerned Regarding Increasing Spread of West Nile Virus As They Announce Third Case In a Human
Division of Public Health (DPH) officials are concerned about the increasing number of cases of West Nile Virus (WNV) in humans this year. DPH is announcing that WNV is confirmed in a 73-year-old New Castle County man, who has been hospitalized since late August. This is the third case of WNV confirmed in humans in the last month. The first case involved a 60-year-old Sussex County man, and the second a 68-year-old New Castle County man. Additionally, DPH is awaiting results from the Centers for Disease Control and Prevention (CDC) in a fourth potential case of the disease. Last week, the Delaware Department of Agriculture announced two cases of WNV in horses.
