West Nile Virus Activity Intensifies Throughout Yolo County


August 8, 2012


Elk Grove, Calif.— The Sacramento-Yolo Mosquito and Vector Control District continues to closely monitor areas throughout Yolo County where West Nile virus activity has intensified in the past week. Widespread activity has been found throughout Woodland, Davis, Knights Landing, and Dunnigan.  Test results obtained today confirmed that a total of 29 mosquito samples were positive.  “We continue to see extremely high levels of West Nile Virus activity throughout populated and rural areas of the county and we are very concerned” said David Brown District Manager. Surveillance results indicate that the activity to date is the most that has been registered in the county since 2006.

Adding to the concerns are the very hot temperatures expected over the next few days and the increased abundance of mosquitoes being caught in some of the traps. “Lab staff collected traps that had more than 400 mosquitoes each. With such an increase in mosquitoes, the risk of being bitten by an infected mosquito is enhanced” added Brown.

In response to this activity and new positive mosquito samples the District will intensify ground treatments and conduct aerial treatments over known agricultural sources to quickly reduce the infected mosquito population and protect public health. The District continues to urge the public to inspect their homes for any stagnant water and asks for public cooperation in identifying any mosquito breeding sources.

West Nile virus activity has also increased throughout the state. To date, 29 counties have registered activity. A total of 13 human cases have been reported in 2012.
