WNV can produce severe diseases in horses, the press release stated. Because horses are outdoors and attract hordes of biting mosquitoes, they are at high risk. Typical symptoms in horses include staggering, circling, depression, loss of appetite and sometimes fever.
Unlike Eastern Equine Encephalitis (EEE), horses usually recover from WNV. Generally both WNV and EEE can be prevented through vaccination.
Health district officials advise horse owners to vaccinate animals every six to 12 months against the disease. Vaccination includes initial shot, with a booster six weeks later, then boosters every six to 12 months. Vaccinations must be administered correctly and in a timely fashion to be effective. Horse owners should contact their veterinarian for further information. There is no effective vaccination for humans.
The viruses are spread to birds, humans and other mammals through the bite of an infected mosquito. Arboviral infections can be prevented by controlling mosquito population and protecting against mosquito bites.
