West Nile Virus
The most common way the West Nile virus is transmitted to workers is by the bite of a mosquito. Most people infected with West Nile virus will not have any symptoms. About 1 in 5 people who are infected will develop a fever and other symptoms. Less than 1% of those infected develop a serious, sometimes fatal, neurologic illness.
Employers should provide workers with training about West Nile virus prevention and symptoms of infection, and provide EPA-registered insect repellent and protective clothing. Workers can prevent mosquito bites by using insect repellent and wearing protective clothing that covers their skin.
