City finds first mosquitos with West Nile Virus this year

A third person has been infected with the West Nile virus in Grand County, and the virus has been been found in mosquitoes in Utah County - although there have been no reports of human cases there. CCHHS will continue trapping and testing mosquitoes in areas where there is mosquito activity until colder weather returns.

The cases, reported in Custer County and Lewis & Clark County, both happened to people over the age of 60, who are often at greater risk for severe disease, according to a press release from the Montana Department of Public Health & Human Services.

So far this year, 41 states have reported cases of the virus, and there have been 206 reported cases, the CDC says.

The CDC recommends using insect repellent and wearing long-sleeved shirts and trousers while outside to help avoid contact with mosquitoes which could be carrying the virus.

Mosquitoes carrying the virus bite between dusk and dawn.

Permethrin-treated clothes provide protection after multiple washings; do not use permethrin (an insecticide that repels and kills mosquitoes) directly on skin.

About one per cent of people infected with West Nile Virus will experience inflammation of the brain or brain lining, the city said.

Most people (8 out of 10) infected with WNV do not develop any symptoms.

The elderly are at greatest risk for severe complications.

The number of West Nile virus confirmations typically rises as the season progresses, peaking late in the summer.

Montana averages 37 cases of West Nile per year, though numbers can fluctuate wildly from single digits into the hundreds.

On Tuesday, the TriCounty Health Department announced a confirmed case of human-contracted West Nile virus within the Uintah Basin. In addition, one equine case of WNV was identified in Lake County this season.

Anyone who thinks they have West Nile virus symptoms should contact their healthcare provider.
