–The Public is Urged to Protect Themselves During the Holiday weekend

Elk Grove, Calif.— The Sacramento-Yolo Mosquito &Vector Control District announced that more evidence of West Nile virus activity has been detected in Sacramento County as four more mosquito samples and a bird tested positive for the disease. “Hot temperatures in recent days have accelerated the production of mosquitoes and West Nile virus is on the rise putting the public at a higher risk” said David Brown, District Manager.

The increased West Nile virus activity comes at a time when many will be enjoying the outdoors this holiday weekend and the District reminds the public to take protective measures against mosquitoes. “Many will be enjoying the weather and taking part in family BBQ’s and watching fireworks around dusk, a time when mosquitoes are most active. We urge you to wear an effective repellent to prevent mosquito bites. All it takes is one bite from an infected mosquito to get the disease,” said Brown. The Center for Disease Control recommends using an insect repellent that contains the active ingredients DEET, Picaridin, IR3535 or the plant based Oil of Lemon Eucalyptus.

Last week 2 mosquito samples and one bird tested positive for West Nile virus in Sacramento County. Though the District has not seen any virus activity in Yolo County to date, two potential human cases are currently being investigated by the Yolo County Department of Public Health.

In response to the recent findings, the District has increased its surveillance and started ground fogging around areas where positive mosquitoes and birds have been found.
