West Nile Virus Activity Spreads to Yolo County

August 26, 2011

–First mosquito sample and a dead bird test positive

Elk Grove, Calif.— The Sacramento-Yolo Mosquito & Vector Control District announced today that West Nile Virus activity has spread to Yolo County as the first bird and a mosquito sample have tested positive for the virus. The bird which was collected in south Davis near Chiles Rd. and Mace Blvd. and the mosquito sample found near County Rd. 103 between Woodland and Davis are the first indications of West Nile virus activity for the county. “Finding this first positive bird and mosquito sample is significant because it shows that the virus is moving to new areas” said David Brown, District Manager. “Although we’ve had a mild summer, we are still seeing many mosquitoes and this is a clear sign that we need to remain vigilant and take proper precautions against mosquitoes to prevent being infected,” said Brown. Until now most of the WNV activity had been centered in Sacramento County, especially in the Elk Grove and Wilton areas.

The District urges the public to do their part in reducing mosquitoes and protecting themselves to decrease the chances of contracting West Nile virus. “Inspecting your yard for standing water and wearing an effective insect repellent during times of peak mosquito activity continue to be your best line of defense.” said Brown.

In recent days WNV activity has amplified throughout the state and so far there are 13 confirmed human cases. While most cases have been found in southern California, a 74 year old Stockton man was hospitalized and diagnosed with the virus. This is the first known case in neighboring San Joaquin County.

In response to the recent findings in Yolo County, the District will increase its mosquito trapping and monitoring in the area to find sources where mosquitoes may be breeding and follow the guidelines outlined in the Mosquito-Borne Disease Management Plan.
