First Two Mosquito Samples Test Positive For West Nile Virus In Sacarmento County


June 25, 2010


Elk Grove, Calif.—The Sacramento-Yolo Mosquito and Vector Control District (District) received notification today that two mosquito samples have tested positive for West Nile virus (WNV). The mosquito samples are the first ones to test positive this year in Sacramento County and were collected from traps in South Sacramento. “Finding the first samples of infected mosquitoes is another reminder that that the virus is active and present in our area.” said David Brown, District Manager. “Residents need to be aware and take proactive measures to protect themselves because West Nile virus is here to stay” said Brown.  As temperatures continue to rise and days get longer, mosquitoes will continue to be a problem and it is very important that the public be aware and take proactive measures such as draining any sources of standing water around their home, dressing appropriately and using an effective repellent especially at dawn and dusk when mosquitoes are most active. As the weather gets hotter and especially with possible triple digit heat expected over the weekend, the District will continue to see increased mosquito activity.

As a response to the detection of WNV, the District will increase its mosquito trapping and surveillance in the area to find sources where mosquitoes may be breeding. Ground spraying may also be conducted to rapidly decrease the numbers of adult mosquitoes.

The Sacramento-Yolo Mosquito and Vector Control District provides year round mosquito and vector control services. The main goal for the District is to keep the public healthy by preventing the transmission of diseases and improving the quality of life for residents.
