FIRST MOSQUITO SAMPLE OF THE SEASON TESTS POSITIVE FOR WEST NILE VIRUS
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 Gibson Ranch near Elverta in Sacramento County. “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. Other areas of the state, including Alameda and Santa Clara counties as well as several others in Southern California have also begun reporting West Nile virus activity. Last year in California there were 131 confirmed human cases of the disease, including 12 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.
