West Nile Virus 2013: Lafayette, Golden Mosquitos Test Positive For West Nile Virus

Mosquitos in Lafayette and Golden, Colo. have tested positive for the West Nile Virus, according to health officials.

Mosquitos in multiple locations in both cities have now tested positive for the virus, according to 7News.

A concert featuring Phat Daddy that was to be held at Waneka Lake in Lafayette Wednesday evening has been moved to 7 p.m. at Festival Plaza. Waneka Lake was one of the areas in Lafayette that tested positive for West Nile Virus.

9News reports that there are no reports of any human cases in Golden or Lafayette at this time.

Mosquito control efforts are being deployed in both cities.

The first case of West Nile Virus was reported in Delta County, Colo. earlier this month, the state health department told The Associated Press.

Last year in Colorado, there were 131 reported cases of West Nile virus with five deaths. The AP reports that the peak year for the mosquito-borne disease was in 2003 with 2,847 reported cases and 63 deaths.

Nationally, U.S. health officials say that 2012 was the worst year ever for West Nile deaths with 286 total deaths -- two more than the 2002 record.

County health officials are reminding everyone in Colorado to follow the four "Ds" to help prevent mosquito bites:

• Use DEET or another insect repellent every time you are outside
• DRAIN all standing water around your home and replace water in kiddie pools and bird feeders every five days.
• DRESS properly in long sleeve shirts and long pants while outdoors.
• At DAWN and DUSK when mosquitoes are most active, limit your outside activity.
