West Nile virus detected in Laramie mosquito sample


CASPER, Wyo. — The City of Laramie has announced the discovery of West Nile virus in a mosquito sample collected within the city.

According to city officials, the positive sample was isolated in mosquitos collected from surveillances traps monitored by City of Laramie Mosquito Control. The traps were reportedly located within the city limits.

“The samples were determined to be positive for West Nile using the City’s Rapid Analyte Measurement Platform analyzer on June 13th,” the city said in a written release Friday morning. “The samples will be sent to the Wyoming State Veterinary laboratory for confirmation.”

The City of Laramie says that the rating of the Risk of West Nile virus infection continues to be rated at Level 1, signifying low risk. The risk level is based on the Centers for Disease Control guidelines “for a phased response to [West Nile] surveillance data.”

City of Laramie Mosquito Technicians have tested a total of 3 samples of mosquitoes during the month of June.

No avian, equine, or human cases have been reported at this time in Albany County.

Wyoming Department of Health has reported one human noninvasive locally acquired case in Campbell County.

“Current surveillance locally shows low numbers of vector mosquitoes being collected at trap locations adjacent to the Big Laramie River and in some rural locations,” the city statement says. “Residential surveillance sites within the city limits report low vector numbers.”

Mosquito control will continue in Laramie’s residential neighborhoods with city fogging operations.

Laramie Mosquito Control is also reportedly performing targeted fogging operations to control mosquitoes in areas of higher densities and areas where citizens often recreate in the evening hours.

“Citizens are reminded that WNV can infect people of all ages, but the elderly may be at the  greatest risk for a serious infection. Locally, the mosquitoes that transmit WNV 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.
