Treatment, Control and Prevention
No treatment approved for human use to date, although there are vaccines available for animal use.
Current Tx: supportive care (intravenous fluids and breathing support by ventilation)
1. Decrease contact with mosquito vectors
Prevention during peak seasons most important: mid-April to late September or October
Use insect repellent
Minimize time outdoors when mosquitoes are most active (dawn/dusk)
Remove stagnant water where mosquito larva and pupae develop
Remove decaying organic matter and shrubs where mosquitoes breed and rest
Prevent mosquito from entering indoors via window screens
Wear protective clothing
Use insecticides to control the mosquito population
