Treatment and Prevention

Currently, there is no antiviral treatment for WNV, EEE, or WEE. The diseases may be managed by controlling inflammation and by using anti-inflammatory drugs and other supportive measures including IV fluids, nutritional support, and sedatives. Your veterinarian can help you design the regimen that is right for your horse.

The best ways to protect your horse from WNV is to vaccinate and limit exposure to mosquitos. Your veterinarian can advise you on the vaccine schedule that’s right for your horse. Make an effort to reduce the breeding area for mosquitos on your property:

Protect yourself with clothing layers and mosquito repellent
Eliminate areas with standing water
Keep horses indoor from dusk to dawn, and screen stalls or install indoor fans
Clear roof drains and gutters
Remove old trash, tires, and receptacles that may collect water
Move birds (including chickens) away from your horse
Clean watering troughs at least once per month
Turn stable lights off at night and place incandescent bulbs or electric bug zappers around your perimeter to lure away mosquitos
Consult your veterinarian about insect repellents for your horse
Consider larvicides or adulticides
