More evidence of West Nile virus has been detected in Yolo and Sacramento counties as 26 mosquito samples tested positive Wednesday, the Sacramento-Yolo Mosquito & Vector Control District announced.
“We are continuing our surveillance and control efforts,” said David Brown, district manager. “To date, we’ve seen a favorable response to the work we performed, and the abundance of mosquitoes is lower than it was last week. However, this time of the year the virus can quickly amplify, so we must not let our guard down.”
The news comes at a time when many residents are enjoying summer outdoor activities in the evening, at a time when mosquitoes are most active.
Brown reminds people to use insect repellent that contains the active ingredients DETT, picaridin, R3535 or the plant-based oil of lemon eucalyptus.
In 2012, 20 deaths and 479 human WNV cases were reported in California.
