West Nile virus confirmed in mosquitoes in Washoe Co., Carson City, Mason Valley
Listen to the story
State officials have identified mosquitoes infected with the West Nile virus in Washoe County, Carson City, and Mason Valley.
The Nevada Department of Agriculture has confirmed the potential for viral transmission of the West Nile virus to humans in these areas. Earlier this month, department officials also reported positive mosquito pools in Douglas County.
State Veterinarian Anette Rink says the recent heat has only added to the severity of this public health threat.
"After weeks and weeks of really warm temperatures, we do have a very conducive climate to mosquito development. And temperatures like we have right now, it only takes about three days for mosquito larvae to hatch."
This year there have been four confirmed cases in Clark County, including one fatality. Nevada has seen cases of the West Nile virus in humans since 2003.
