West Nile found in mosquitoes trapped north of Genoa

Mosquitoes that have tested positive for West Nile Virus have been found north of Genoa in Carson Valley, according to the Douglas County Mosquito Abatement District.

“We are taking action tonight with a ground adulticiding attack followed by an aerial adulticiding application,” District Manager Krista Jenkins said Wednesday. “We strongly advise people to wear long sleeve shirts and pants in the early morning and evening hours and to use an insect repellent with Deet. We will continue to monitor the area. Trapping for mosquitoes will occur after the adulticide applications and sent into the state for testing.”

The sample was the first to test positive for West Nile Virus in Northern Nevada this year, according to the Nevada Department of Agriculture’s Animal Disease and Food Safety Laboratory.

Clark County has already reported human cases of West Nile Virus.

More than 700 samples from statewide surveillance have been submitted to the laboratory at the Department’s Sparks office since May.

“All horse owners should update their animal’s West Nile Virus vaccination,” said Dr. Annette Rink, acting state veterinarian and supervisor of the Animal Disease and Food Safety Laboratory.

Four effective vaccines exist for horses, but vaccine development for humans is still under way with currently no available product in sight. The potentially serious disease first appeared in Nevada in 2004, affecting people horses and relatives of the magpie. It flares up in summer and continues into the fall. Residents are asked to drain standing water to prevent mosquitoes from breeding.
