RENO, Nev. (AP) — The first human case of West Nile virus has been confirmed in Washoe County.
County health officials said Tuesday the case involves a man over 50 who could have been bitten by a mosquito while recently traveling outside the county.
However, they say they also confirmed that a sample of adult mosquitoes in the Spanish Springs/Kiley Ranch area on the northeast edge of Sparks recently tested positive for the virus. It marks the third confirmed human case in Nevada this year.
Washoe County officials say recent rains produced standing water where the mosquitoes breed. They say they'll continue to collect samples until there is a hard freeze and are stepping up surveillance and early-morning fogging in the area of Henry Orr Parkway, Turnberry Drive and Vista del Rancho.
