West Nile Virus

  • West Nile virus (WNV) is a potentially serious illness. Most often, WNV is spread by the bite of an infected mosquito. Mosquitoes become infected when they feed on infected birds. Infected mosquitoes can then spread WNV to humans and other animals when they bite.

    WISD works with local health departments that closely monitor area WNV cases. The district will take specific precautions as warranted and/or at the direction of health authorities.
