The city of Aspen’s environmental health department is beginning “surveillance activities” to identify any potential cases of West Nile virus, according to a press release. West Nile is a mosquito-borne virus that can cause mild to severe illness in humans and animals. It is spread to humans almost exclusively through the bite of an infected mosquito.
Trapping in lower elevations of the state usually begins in May, but Aspen’s cool climate helps to slow the arrival of mosquitoes, according to city officials. Mosquito traps in the area have so far turned up relatively empty, with only a few dozen mosquitos trapped.
The city has found only one Culex mosquito, the species that carries West Nile virus, in about five years of surveillance.
Although there have been no confirmed cases of West Nile virus in the valley to date, mosquitoes emerging might be infected with the virus and pose a health risk to the general public.
People can defend themselves against West Nile by using a DEET-enhanced insect repellent, dressing in long sleeves and pants, avoiding the outdoors at dawn and dusk (the most active times for mosquitos) and draining standing water around their homes. Buckets, flowerpots, saucers, kiddie pools, patio furniture covers, and bird baths should be drained every few days to decrease the potential for providing a West Nile virus breeding ground.
The environmental health department, on the second floor of Aspen City Hall, has free samples of Bite Blocker (DEET-free spray) and Skeet Safe DEET towelettes.
