Biological Hazards | 10-15 min
Summary
West Nile Virus is a mosquito-borne illness that poses risks to outdoor workers across North America. First detected in the United States in 1999, it has since spread to all 48 contiguous states. Most infected people have no symptoms or mild flu-like illness, but approximately 1 in 150 infected people develop serious neurological illness that can include encephalitis (brain inflammation), meningitis (inflammation of membranes around the brain), or paralysis.
