The Health Department said it "evaluated standing water around the resident’s home and nearby catch basins, and treated those with larvicide as needed."
“This first case of West Nile Virus should remind us all to take precautions against mosquito bites by removing standing water from our property," County Health Commissioner Dr. Sherlita Amler, said, "especially after recent heavy rain and flooding, and using repellents when we spend time outdoors, especially from dusk to dawn, when mosquitoes are most active.”
