West Nile Virus Confirmed in Washoe County

Posted: Updated:
Washoe County's first case of West Nile Virus has been confirmed after a sample of adult mosquitoes tested positive for the virus.


Lainee Weiner has two horses that she keeps at the Spanish Springs boarding stable.
Knowing that the West Nile Virus turned up only about a mile from here has her concerned.

"I have an older horse and they are definitely more susceptible and I will definitely be getting him vaccinated, this week."

The health department says all horses should get vaccinated for the virus.
This week's positive test came from the Kiley Ranch area where recent rain and humidity has attracted more mosquitoes.

"This is what we caught the positive sample in."

Portable surveillance traps are set up around Washoe County.

At least one of the 29 adult females from the Spanish Springs batch was carrying West Nile Virus.

"It tells us that you don't need a large number of mosquitoes to go ahead and transmit the virus," says Jim Shaffer, Vector Borne Disease Program.

Mosquito abatements have already happened on 900 acres around the Truckee Meadows, this summer killing larvae in area wetlands.         
Testing for mosquito-borne illnesses goes on throughout the summer.

"By having these early indicators, by trapping, it prevents it from moving into the human population."

Homeowners can do their part to fight mosquito populations too by getting rid of any standing water in the yard.
And mosquito fish are available for anyone with water features on their property.

"If you have mosquito fish, we have them for ponds for backyards, water features, and also for troughs."

There have been no confirmed human cases of West Nile in Washoe County, this year.

But this latest case is raising awareness.

"Ever since I've lived in Sparks, I've heard it come on and off every other summer and it makes me nervous but not to the point that I don't go out,” says Spring Robinson of Sparks.

Because of this positive test, the health district will fog in the Wingfield Springs area again Friday morning.

They also plan on abating another 1,000 acres next Wednesday.

Anyone spending time outside, during the morning or evening should use mosquito repellent with DEET and wear long sleeves and pants to keep from getting bitten.
