Year's first Carson Valley West Nile Virus case found in person

By  | 

CARSON CITY, Nev. (KOLO) - The first case of West Nile Virus infection in a person in the Carson Valley area has been reported for 2017.

The person with the virus has the most serious form, which can affect the brain and surrounding tissues, Carson City Health and Human Services said in a Friday statement.

CCHHS and Douglas County Mosquito Abatement reported the case.
The report coincides with the first positive collection of a mosquito in Carson City that has the virus. CCHHS said the collection and the infection are not related.

CCHHS will treat the areas where mosquitoes might breed to keep the virus from spreading. Mosquito surveillance and abatement activities have already been done this summer in Carson City and Douglas County and will continue.

Meanwhile, El Dorado County health officials said a Steller's Jay found July 31 in South Lake Tahoe has tested positive for the virus. Mosquitoes get the virus from birds.

So far this year, West Nile virus activity has been reported in 28 California counties, including neighboring Sacramento and Placer counties, El Dorado County health officials said. There have been four human cases of the virus reported from Kings, Kern, San Bernardino and Los Angeles counties.

Mosquitoes transfer the diseased by biting people. It not passed from human to human. The best way to prevent it is to avoid bites. They pass along these tips:

• 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.
