West Nile Virus


Mosquitoes are a natural part of summer in the Northwest and with mosquitoes come the threat of West Nile virus. Protect yourself from West Nile virus. Understand the dangers and remember five simple steps to fight the bite.
 
West Nile Virus Basics:

  • The virus is passed from infected mosquitoes to people through mosquito bites. It is not passed from person to person.
  • It can cause a potentially serious illness that affects the central nervous system.
  • Washington reported three human cases and detected the virus in eight counties last year.  Numerous people were infected in Idaho and Oregon.
  • It often causes symptoms similar to the flu.
  • The virus can be very serious - even deadly - for some people, especially those over age 50.
  • West Nile virus may cause some people to develop severe illness, including a high fever, headache, neck stiffness, and/or disorientation.
Five Quick Tips:
  • Use an effective repellent.
    • DEET is safe and is the most effective repellent; other options include Picaridin, oil of lemon eucalyptus (or PMD), and IR3535.
  • Wear long sleeves, long pants, and socks outdoors whenever possible.
    • Make sure to do this especially at dawn and dusk when mosquitoes are most active
  • Remove water that collects around your home by keeping water fresh in pet dishes and birdbaths.
    • Mosquitoes need only a small amount of water to breed.
  • Make windows and doors "bug tight" with screens.
    • Close doors behind you and if mosquitoes are thick in your area, consider netting or screens around your deck.
  • Share what you know.
    • Help protect your friends, family, and neighbors against West Nile virus by sharing these tips.
Testing dead birds is one of the ways the virus is tracked in our state. Watch for and report dead crows, ravens, jays, magpies, and hawks as they often die from West Nile infection. Learn more by calling 866-78-VIRUS.  You can also find information and report dead birds online at www.doh.wa.gov/wnv.
