Mosquitoes buzzing, bringing West Nile virus concerns

OLYMPIA ¾ More mosquitoes are buzzing as summer approaches, raising the state Department of Health’s concerns about West Nile virus. Luckily, no people contracted the mosquito-transmitted disease last summer in Washington — but eight horses, one bird, and one dog tested positive for the virus in Yakima County.

"We’ve been fortunate that West Nile virus hasn’t hit our state hard, but the virus is here in birds and mosquitoes," said Gregg Grunenfelder, environmental health division assistant secretary for the state Department of Health. "As we’ve seen in Idaho and Oregon, this virus can make a lot of people sick — or worse — so preventing mosquito bites is the best way to avoid infection."

The key is to avoid mosquito bites and reduce mosquito larvae habitat:

  • Stay indoors when mosquitoes are most active (dusk to dawn).
  • Make sure the screens on doors and windows are working properly.
  • Cover exposed skin with light colored clothing when outside in the evening.
  • Use an effective repellent on exposed skin. Always follow the directions on the label.
  • Reduce mosquito larvae habitat around the home by dumping standing water.
  • Change water in birdbaths, fountains, wading pools, animal troughs, and other sources once or twice a week.
    •

    West Nile infection can be very serious, and even fatal, for some people. While most people bitten by a mosquito carrying West Nile virus don’t become ill, some may have mild to severe flu-like symptoms. A small number of people may develop a serious neurological disease. People over 50 and those with compromised immune systems are at greater risk for serious illness.

    Anyone who finds a freshly dead crow, magpie, raven, jay, or raptor should report it to their local health agency. These birds often die after being infected with West Nile virus and can act as an early warning for communities that mosquitoes in the area may be carrying the virus.

    Horses are also susceptible to West Nile virus, but vaccines and an annual booster can protect them. Horse owners should contact a veterinarian to learn about vaccinating horses against West Nile virus.

    More information on West Nile virus (www.doh.wa.gov/WNV) is available on the Department of Health’s Web site or by calling the agency’s toll-free phone line, 1-866-78VIRUS.
