A horse in Fulton County has tested positive for West Nile Virus , according to a release issued Monday from the Fulton County Health Department. The release says although a Tazewell County resident has been diagnosed with the virus, equine cases are an indicator of increased risk of West Nile to humans. West Nile is transmitted through the bite of a mosquito that has picked up the virus. Most people with the virus have no clinical symptoms of illness, but some may become ill three to fourteen days after the bite of an infected mosquito. Mosquitoes stay active until there is a hard freeze.
