West Nile Virus Activity on the Uptick in Elk Grove

August 14, 2017 |  

The Sacramento-Yolo Mosquito and Vector Control District reports increased West Nile virus activity throughout the District and especially around Elk Grove. Last week there was an increase in the amount of mosquito samples that tested positive from urban and rural traps. 

“We’re closely monitoring and keeping an eye on Elk Grove since WNV activity is steadily rising,” Gary Goodman, District Manager said. “This is an area of concern for us and to date, most of the mosquito samples that have tested positive are located between I-5 and Hwy 99 and from Laguna Blvd to Twin Cities Rd.

In response to the increased WNV activity, the District will continue surveillance efforts testing mosquitoes for virus, treating mosquitoes in all known aquatic sources and performing adult mosquito control as necessary.

Throughout the state, West Nile virus activity continues to steadily increase and to date it has been detected in 31 counties.  In 2016 there were 442 human cases and 19 deaths related to West Nile virus.

The District also reports a reemergence of St. Louis encephalitis, a virus spread by the same mosquito species that can transmit West Nile virus. In the last couple of weeks, St. Louis encephalitis has been moving north being detected in Placer, Yuba and Stanislaus counties as well as in other areas of the state.
