West Nile Virus Found in Washoe County, Carson City, Mason Valley

Posted: Updated:

The Nevada Department of Agriculture has confirmed the presence of West Nile Virus in Washoe County, Carson City and Mason Valley.

Officials tested dozens of areas including wetlands, ditches and other small bodies of water.

West Nile Virus is transmitted when mosquitoes feed on infected birds and pass it on to other birds, animals and people. It is not spread by person-to-person contact.

West Nile was first detected in this area in 2004.

Mosquito season in this area usually ends with the first killing frosts in October.

Until then, area residents are reminded to take the following precautions during summer months to prevent an increase in the mosquito population in and around their homes:

•Clear the yard area of any free-standing water that may become a mosquito breeding-ground

•Wear long sleeves and long pants in mosquito prone areas

•Use mosquito repellant and follow label precautions

•Repair any window screens that provide entry for mosquitoes

•Vaccinate horses for Western Equine Encephalitis (WEE)

•Vaccinate horses for West Nile Virus (WNV). Four effective vaccines exist for horses, but vaccine development for humans is still underway with currently no available product in sight.

•Report night-time mosquito activity to the District Health Department at 328-2434

The Dept. of Agriculture says products containing the below active ingredients typically provide reasonably long-lasting protection:

• DEET (Chemical Name: N,N-diethyl-m-toluamide or N,N-diethly-3-methyl-benzamide)
• Picaridin (KBR 3023, Chemical Name: 2-(2-hydroxyethyl)-1-piperidinecarboxylic acid 1-methylpropyl ester )
• Oil of Lemon Eucalyptus* or PMD (Chemical Name: para-Menthane-3,8-diol) the synthesized version of oil of lemon eucalyptus
• IR3535 (Chemical Name: 3-[N-Butyl-N-acetyl]-aminopropionic acid, ethyl ester)

EPA characterizes the active ingredients DEET and Picaridin as "conventional repellents" and Oil of Lemon Eucalyptus, PMD, and IR3535 as "biopesticide repellents", which are derived from natural materials. For more information on repellent active ingredients, please visit: http://www.epa.gov/pesticides/health/mosquitoes/ai_insectrp.htm.

For other information, visit the WCHD web site at www.washoecounty.us/health or the Centers for Disease Control and Prevention at www.CDC.gov.

In response, the Washoe County Health District will target certain areas to prevent the virus from spreading.

Crews with the district's Vector-Borne Disease Control Program will conduct mosquito "fogging" bright and early Wednesday morning. They'll be working in south Reno bordered by South Meadows Parkway, Rio Wrangler Road, Gieger Grade and U.S. Highway 395.

The fogging -- which involves a mist of insecticide will happen throughout the morning to combat West Nile and reduce mosquito activity.
