Original Story: The Washoe County Health District Vector-Borne Disease Program says mosquito samples from the Hidden Valley and Rosewood Lake areas tested positive for West Nile Virus.

They said no human cases have been reported in Washoe County so far this year.

Washoe County officials say the Health District will increase mosquito surveillance and will conduct early-morning insecticide fogging on Thursday in the area.

The Health District says about one in five people with the virus will have mild symptoms like headache, body aches, joint pains, vomiting, diarrhea or rash. Most people with this type recover completely, but fatigue and weakness can last for weeks or months, they said.

The Health District says about one in 150 will develop a more severe illness affecting the central nervous system. Symptoms include high fever, headache, neck stiffness, disorientation, coma, tremors, convulsions, muscle weakness, vision loss, numbness and paralysis. They said about one in ten of those people will die from the illness.

They said there are multiple ways to prevent West Nile Virus:

  • Wear proper clothing and repellent if going outdoors in early morning and evening
  • Use Environmental Protection Agency registered insect repellent
  • Make sure doors and windows have tight-fitting screens
  • Clear areas around your home of any free-standing water such as small puddles, pools, planters, sandboxes, wagons or toys, around faucets, plant saucers and pet bowls
  • Vaccinate horses for West Nile Virus
