A pool of mosquitoes trapped recently in the northern portion of the Waneka Reservoir near Lafayette's Waneka Lake Park has tested positive for carrying the West Nile virus, according to Boulder County Public Health.
There were 13 cases of West Nile reported in Utah previous year, according to the Center for Disease Control and Prevention, with one case resulting in death.
Downey explained that of all the people bitten by a mosquito with West Nile, only 20 percent show any symptoms at all - 80 percent are asymptomatic and display no signs of illness. The symptoms of West Nile fever include: fever, headache, body aches, fatigue, skin rash, swollen lymph glands and eye pain.
Officials confirmed two local batches of mosquitoes have tested positive for West Nile virus.
The types of mosquitoes that can carry these viruses are most active throughout the evening and night, from dusk until dawn.
The department's Juan Rodriguez said they want people to realize that anyone can become infected.
The inmate, housed at The Louisiana State Penitentiary at Angola, was taken to a hospital after suffering from flu-like symptoms and high fever, according to a relative. About 10% of people who develop neurologic infection because of West Nile Virus die.
But some human cases can be more severe. People need to be vigilant about personal protection.
Remove standing water that can become breeding ground for mosquitos and install or fix screens to keep mosquitos outside.
Wear a long sleeve shirt, long trousers, and a hat when going into mosquito-infested areas, such as wetlands or woodlands.
