Elk Grove, Ca.—The Sacramento-Yolo Mosquito and Vector Control District  confirmed today that the first mosquito sample of the season has tested positive for West Nile virus (WNV).  The mosquito sample was collected from Bond Rd. near Highway 99 in Elk Grove.  “As we expected, the very warm weather we’ve had recently increased the number of mosquitoes and accelerated virus activity,” said Gary Goodman, District Manager. “It’s important for residents to take these findings seriously and do everything they can to protect themselves,” added Goodman. Two weeks ago, a bird collected from Carmichael was the first bird of the season to test positive for the virus. Other counties throughout the state, including neighboring San Joaquin County, have also started to report West Nile virus activity.  Last year in California there were 225 confirmed human cases of the disease, including six fatalities. 
The detection of this recent WNV activity is evidence that the disease is present and the public should take proper precautions to stay protected. “Summer is around the corner and as more people enjoy outdoor activities it’s important to remember that the best protection against mosquito bites is an effective insect repellent,” said Goodman. Residents are also encouraged to report dead birds, neglected pools and other mosquito problems.
As a response to the finding of WNV, the District will increase its mosquito trapping and monitoring in the area to find sources where mosquitoes may be breeding. Targeted ground spraying may also be conducted to rapidly decrease the numbers of adult mosquitoes.
