Less than 1 percent of people who are infected will develop serious neurologic illness such as encephalitis or meningitis.
Those who do become sick usually experience symptoms including fever, headache, muscle aches, rash and fatigue. Symptoms can last for as short as a few days, though even healthy people have been sick for several weeks. The agency also advises people to use insect repellent, fix and replace worn screens on doors and windows, and remove stagnant, shallow water or puddles on a weekly basis to prevent mosquitoes from breeding.
Use a mosquito repellent with an EPA-registered ingredient such as DEET while you are outdoors.
