West Nile virus found in mosquitoes in Laramie

By  | 

LARAMIE, Wyo. (KGWN) - West Nile virus has been documented in two separate mosquito samples collected this week in Laramie. The positive samples were isolated in trapped mosquitoes on Friday. The mosquitoes were trapped within the City limits.

The rating of the Risk of West Nile virus infection continues to be rated as a low risk based on CDC guidelines. Currently virus activity is categorized as “Limited to sporadic activity in local mosquitoes and birds”. As of right now, no avian, equine, or human cases have been reported at in Albany County. Wyoming Department of Health has reported mosquito positive samples from Goshen County and Laramie County. An equine case has been reported in Campbell County. Currently no human cases have been reported in the state.

Although total mosquito numbers are currently low, mosquitoes that can effectively transmit the virus make up a greater percentage of the mosquito population in late summer due to the overwintering and reproduction cycles of the species.

Mosquito control will continue to fog perimeter neighborhoods where mosquito numbers are greater. A return to full fogging will be evaluated at a later time. Targeted areas include: Parks and recreation areas, golf courses, and the Laramie River Greenbelt Trail. All “No Spray” zones will continue to be honored.

Citizens are reminded that West Nile can infect people of all ages but the elderly may be at the greatest risk for a serious infection. Locally, the mosquitoes that transmit West Nile are most active after dusk and citizens should limit activities in areas with high mosquito populations during this time. Repairing screens, especially in sleeping rooms, and using personal protection such as proper clothing and insect repellent containing DEET can also reduce the risk.
