West Nile Virus Activity Expands into New Areas


September 9, 2011


Protection against mosquitoes continues to be important

Elk Grove, Calif.— While the Fall season is only a couple of weeks away, the hot temperatures of recent days have brought many mosquitoes and West Nile virus activity has amplified and continues to be a threat.  The Sacramento-Yolo Mosquito & Vector Control District announced today that 9 new mosquito samples and 4 new birds have tested positive for the virus. “West Nile virus activity is expanding into areas that we hadn’t seen so far this season” said David Brown, District Manager. “Personal protection with an effective insect repellent is more important than ever. It only takes one bite from an infected mosquito for you to become seriously ill” added Brown.

The majority of WNV positive mosquitoes have been found in the Wilton and Elk Grove areas, however new activity has now been detected near Capitol Park and Crocker Park in downtown Sacramento as well as Tahoe Park. This season, weather patterns have been very different than in previous years and WNV activity has been ongoing and steady   “As long as we have hot temperatures, we will continue to see mosquitoes. Infection rates are still high and we urge everyone to not let their guard down,” said Brown.

As a response to the recent findings and heightened activity, District staff will inspect the area for mosquito breeding sources, continue with extensive trapping and surveillance as well as evaluate the appropriate treatment options to ensure public health and reduce mosquito populations.

Up to now, there are no local human WNV cases, however, throughout the state, activity has been registered in 26 counties and there are 33 human cases being reported mainly in Central and Southern California.
