West Nile Virus found in GarCo 

The West Nile Virus has been found in mosquitoes in three locations in Garfield County.

The county also reports that high levels of Culex tarsalis, the kind of mosquito that carries the disease, were found in six trapping locations last week.

The Colorado Department of Public Health and Environment reported the positive tests for the virus based on samples sent by county contractor Colorado Mosquito Control.

The positive tests involved mosquitoes collected in Willow Creek in Battlement Mesa, Parachute Cottonwood Park and Mile Pond Road, southeast of Rifle.

The county has 11 trap sites, and Culex numbers that approach 50 or more in a trap in a single night are a concern, leading to truck-mounted fogging of the affected area by Colorado Mosquito Control, the county said in a news release.

The county says when numbers reach those levels, residents should take measures such as using an effective repellent, wearing pants and long sleeves at dawn and dusk, and draining standing water where mosquitoes can breed.

Culex trap counts of 112 at Willow Creek in Battlement Mesa and 107 in Parachute Cottonwood Park were recorded last week. Other counts included 95 at the Rifle Rest Area, 66 at Mile Pond Road, 48 at the Silt roundabout and 55 at Coal Ridge High School east of Silt.

Colorado’s first human case of West Nile Virus was reported July 3 in Delta County. The virus can result in no symptoms, or cause mild to severe illness, chronic disability and even death.
