West Nile Virus Detected in Yuba and Sutter Counties
The Sutter-Yuba Mosquito and Vector Control District has detected more evidence of West Nile virus from mosquito collections submitted for testing this week. District manager, Stephen Abshier is saying, “The virus is now considered widespread in mosquitoes throughout the valley floor in Sutter and Yuba Counties.” Additionally, detections of WNV have been made in two dead birds and in three of our sentinel chicken flocks this week. No reports of human infection have been indicated locally, but the risk of human West Nile infection is elevated. Residents should take measures to avoid mosquito bites. The District’s mosquito-borne disease surveillance system continues to be in full operation and mosquito control efforts are being instituted or enhanced in areas where detections are made.
The District would like to remind the public that prevention of mosquito bites is the best way to protect against West Nile virus and other mosquito-borne viruses at home and when traveling. Taking the following simple steps to prevent mosquito bites are the best ways to keep you and your family healthy. Remembering the 4 “D”s is an easy way to help prevent mosquito bites:
- D – Defend: Use insect repellents containing DEET, picaridin, oil of lemon eucalyptus, or IR3535. These EPA-registered ingredients are proven to be effective in preventing bites. Always follow product instructions, especially when applying to children. Visit the EPA Repellent Search Tool for more information.
- D – Dawn and Dusk: Limit outdoor activities during dawn and dusk when mosquitoes that transmit WNV are most active. If you must be outdoors, wear long sleeves and pants for added protection.
- D – Doors and Windows: Ensure that window and door screens are intact and in good repair to prevent mosquitoes from entering your home.
- D – Drain Standing Water: Mosquitoes lay eggs in standing water. Regularly empty containers such as flowerpot saucers, buckets, tires, and birdbaths. Report neglected or green swimming pools to the District.
Residents are asked to report dead birds to the California Department of Public Health website at www.westnile.ca.gov or by phone at 877-968-2473. You can obtain additional information by visiting our website at www.sutter-yubamvcd.org
