No Positives in Boulder County

June 4th - Boulder County began active mosquito surveillance and testing of dead birds on May 1. To date, no mosquitoes, birds, or horses in Boulder County have tested positive for West Nile virus (WNV). Statewide, one horse in Kit Carson County has tested positive for the virus.

So far this year, 86 dead corvids (i.e. crows, jays, magpies, and ravens) and 47 other WNV-positive dead birds have been reported in 15 states across the country, and 7 WNV infections have been reported in horses from 3 states (Alabama, Arizona, and Texas). As of June 1, two human cases have been reported - one from Arizona and one from New Mexico. In both cases, symptoms of illness began between May 9-13, 2004.

Because WNV can cause such a debilitating illness in 20% of those infected and no treatment is currently available, it is important to remember the "4 Ds" to prevent being bitten by mosquitoes:

Use DEET or alternative.

DRESS in long sleeves and pants.

Avoid DUSK until DAWN.

DRAIN standing water.
