Reno, Nev. Sept. 17, 2019 - A Washoe County resident has tested positive for West Nile Virus (WNV), becoming the first human case in 2019 in Washoe County.

Where the resident became exposed to WNV has not been determined. The person had been fishing along the Truckee River and at the Sparks Marina, but also in Fallon. Local exposure, however, cannot be ruled out.

The Health District’s Vector-Borne Disease Program (VBDP) confirmed WNV in mosquito samples in July and August that were collected in the areas of Longley Lane and South Rock Boulevard, Hidden Valley and Rosewood Lakes.

“Our first confirmed human case of West Nile Virus in 2019 should serve as a reminder to all residents and visitors to Washoe County to take precautions to protect themselves from being bitten by mosquitos," said Washoe County District Health Officer Kevin Dick.

WNV is most commonly spread through mosquito bites. Eight out of 10 people infected with WNV do not develop symptoms; however, in some cases a severe illness and infection can be fatal. Minor symptoms include headache, body ache, joint pain, vomiting, diarrhea or rash. More severe symptoms, which is the case for one in 150 infected, include high fever, neck stiffness, disorientation, convulsions, vision loss, numbness and paralysis.

The Health District’s strategy to help prevent the spread of WNV includes aerial abatement efforts as well as fogging and storm drain treatment, but the most important way to avoid WNV is taking personal action, Dick said.

Prevention tips include:

The Health District is taking additional mosquito abatement actions in in the outdoor areas the person visited.

The Health District has performed five helicopter larvidicing applications in Washoe County in 2019 with the final application scheduled for this month.
