A second Washoe County resident has tested positive for West Nile Virus, but threat levels are decreasing due to colder weather. The person infected with WNV went hiking near the meadows of Mt. Rose in mid-August and developed severe symptoms on Sept. 9th. It is suspected that a mosquito carrying WNV infected the person during this hike. The person sought medical care within days of developing symptoms and is expected to fully recover. Washoe County District Health Officer Kevin Dick says “Most cases of WNV go undiagnosed. The two confirmed cases are indicative of a significantly larger number of undiagnosed cases that probably have occurred in the community.”
