“With the vector index high in two of the testing zones, we encourage residents to take precautions against mosquito bites”, said Wallace.

While the threat of of West Nile is real, there aren’t many mosquitoes around right now, and that trend will continue as long as the weather cooperates.

West Nile virus, already surging in California, has shown up in Sonoma County, twice in three days. The expanded effort is funded by a $525,250 general fund appropriation, which is to help eradicate mosquitoes in the Brandon, Leicester, Salisbury and Goshen areas and for potential aerial pesticide spraying for disease threat reductions.

The NDDoH has made recommendations for people to use insect repellents containing picaridin, DEET, IR3535, permethrin or oil of lemon eucalyptus (PMD). Individuals who develop any of these symptoms should see their healthcare provider immediately.
