RENO, Nev. (AP) - Health officials have confirmed the second case of West Nile Virus in Washoe County this year but they say threat levels are decreasing due to colder weather.

Washoe County District Health Officer Kevin Dick said Wednesday the person infected likely was bit by a mosquito carrying the virus while hiking in the meadows near Mount Rose southwest of Reno in mid-August.

The victim developed severe symptoms in early September, sought medical care within days and is expected to fully recover.

The county’s first case this year was confirmed in September.

That victim had been fishing along the Truckee River and at the Sparks Marina, but also had been in Fallon so authorities don’t know for sure where the virus was contracted.

Eight of 10 people infected with the virus don’t develop symptom but some severe cases can be fatal.
