Fight the Bite!
Helpful Tips

West Nile virus is spread by infected mosquitoes, and can cause serious, life-altering and even fatal disease. Get outside and enjoy the summer, but remember that mosquitoes carrying West Nile virus are on the wing, so apply a mosquito repellent when you're outdoors, especially from dusk to dawn. Check around your yard and dump out standing water where mosquitoes can lay their eggs, too.
