Carson City Health and Human Services is reporting the first human case of West Nile Virus in Lyon County for 2018.

The Disease Control and Prevention Division at CCHHS is monitoring the situation. The individual confirmed to have WNV was diagnosed with the less severe form of the illness, and contracted the virus mosquito bites that occurred out of state. 

This is the first human West Nile virus case to have been reported in the tri-county (Carson City, Douglas County and Lyon County) area this year.

Health authorities say the individual was identified to have WNV through the blood donation pre-screening process.

The most effective way to avoid West Nile Virus disease is to prevent mosquito bites.

• Use insect repellents when you go outdoors. Repellents containing DEET, picaridin, IR3535, and some oil of lemon eucalyptus and para-menthane-diol products provide longer-lasting protection.  More information about insect repellents can be found at

• When weather permits, wear long sleeves, long pants, and socks when outdoors. Mosquitoes may bite through thin clothing, so spraying clothes with repellent containing permethrin or another EPA-registered repellent will give extra protection. Don't apply repellents containing permethrin directly to skin. Do not spray repellent on the skin under your clothing.

• Take extra care during peak mosquito biting hours. Take extra care to use repellent and protective clothing from dusk to dawn or consider avoiding outdoor activities during these times.

• Mosquito-proof your home. Install or repair screens on windows and doors to keep mosquitoes outside. Use your air conditioning, if you have it. Empty standing water from flowerpots, gutters, buckets, pool covers, pet water dishes, discarded tires, and birdbaths on a regular basis.
