Veterinarians in Lambton County, Ontario, have confirmed a 13-year-old Quarter Horse gelding positive for Eastern equine encephalitis (EEE). The horse, which was undervaccinated, started showing signs of ataxia and limb weakness on August 29. Despite receiving supportive care, the gelding is still experiencing neurological deficits. This marks the 17th case of EEE in horses in Ontario this year.
Eastern equine encephalitis is a disease caused by the Eastern equine encephalitis virus, with wild birds serving as natural reservoirs. Mosquitoes that feed on infected birds can transmit the virus to humans, horses, and other birds. While horses do not transmit the virus to other animals or humans, EEE has a high mortality rate in both horses and humans, making it a serious mosquito-borne disease in the United States.
To prevent mosquito-borne diseases like EEE, it is important to:
– Use insect repellent when outdoors, especially from dusk to dawn
– Look for EPA-labeled products with active ingredients like DEET or oil of lemon eucalyptus
– Protect horses with commercially available vaccines against EEE
– Apply approved insect repellents on horses and keep them in enclosed spaces during peak mosquito hours
– Eliminate standing water where mosquitoes can breed
It is crucial for horse owners to take preventive measures to protect their animals from EEE and other mosquito-borne diseases. Vaccination, insect repellents, and environmental management are key strategies in reducing the risk of infection.
