The best way to prevent West Nile virus infection is to avoid mosquito bites.

• Use mosquito-repellant products containing DEET
• Wear long sleeves and pants
• Drain pools of standing water, such as trash bins and plant saucers (mosquitos breed in stagnant water)

Community spraying for mosquitos may also prevent mosquito breeding.

Testing of donated blood and organs is currently being evaluated. There are currently no guidelines.
