The West Nile virus (a flavivirus) is an infection transmitted by mosquitoes. Researchers believe West Nile virus is spread when a mosquito bites an infected bird and then bites a person. Avoiding exposure to mosquitoes is the best way to combat West Nile virus. You can reduce your risk of being bitten by mosquitoes by using repellents such as
OFF! Deep Woods® Insect Repellents and wearing long sleeves and pants where mosquitoes are prevalent.
West Nile Symptoms
If you become infected, you may experience no symptoms or mild flu-like symptoms, such as fever and mild headache. However, some infected people can develop more severe conditions like encephalitis or meningitis.

West Nile Activity
In 2011, at least one case of West Nile virus was found in 42 states and the District of Columbia. The majority of cases occurred in Arizona, California, Nevada, Nebraska, Michigan, Mississippi, and Tennessee.
West Nile Cases
Mosquitoes carry the highest amounts of virus in the early fall, which is why the rate of the disease increases in late August to early September. The risk of disease decreases as the weather becomes colder and mosquitoes die off.
