West Nile Virus Resources for the Pacific Northwest
West Nile Virus is spread by the bite of an infected mosquito, and can infect people, horses, many types of birds, and some other animals. Most people who have become infected with West Nile Virus will have either no symptoms or only mild ones. However, on rare occasions, West Nile Virus infection can result in severe and sometimes fatal illnesses.
National West Nile Information
To reduce the risk of contracting the virus, health officials recommend that people take certain precautions during the summer months. These include:
EPA is not directly involved with the reporting of dead birds or incidences of the West Nile Virus. You should contact your state or local health department with any reports or concerns regarding the virus. For your convenience, we have provided links to West Nile Virus pages that have been posted by states within Region 10.
When necessary, county and local health officials may use ground and aerial application of pesticides, along with non-chemical forms of control, to eliminate mosquitos. Any pesticide sold in the United States, including those used for mosquito control, must be registered with the Environmental Protection Agency (EPA). The EPA reviews health and environmental risk information before deciding whether to register a pesticide.
EPA reviews the label directions of each pesticide product to ensure that, when applied according to label directions, the risks of human exposure and adverse health and environmental effects are minimized. However, no pesticide is 100% safe. Care must be taken to apply pesticides strictly according to the label directions.
If you have questions regarding the health effects of the West Nile Virus or the status of programs addressing the virus in your area, please contact your local county or state health agency. Questions regarding state pesticide laws and regulations should be directed to your state department of agriculture. Questions regarding federal pesticide laws and regulations, including the registration of pesticides, should be directed to the U.S. Environmental Protection Agency.
- Empty standing water in old tires, cemetery urns, buckets, plastic covers, toys, or any other container where mosquitos can breed and live.
- Empty and change the water in bird baths, fountains, wading pools, rain barrels, and potted plant trays at least once a week if not more often.
- Drain or fill temporary pools with dirt.
- Keep swimming pools treated and circulating and rain gutters unclogged.
- Use mosquito repellents when necessary and follow label directions and precautions closely.
- Use head nets, long sleeves and long pants if you venture into areas with high mosquito populations.
- Make sure window and door screens are "bug tight."
- Replace your outdoor lights with yellow "bug" lights.
