 The woman lives in northwest Weld County and reported the onset of West Nile fever on June 22, said Gaye Morrison, a spokeswoman for the county Department of Public Health and Environment. She is recovering at home.  “Conditions have been favorable for mosquitoes to breed. Many people have reported mosquitoes being more bothersome this season,” Dr. Mark Wallace, executive director of the department, said in a news release.  “It is not unexpected that northern Colorado is where the first case of West Nile virus infection has occurred,” he said. “We are thankful the person in Weld County is recovering well. Everyone should take precautions — avoid being out at dusk and dawn, wear protective clothing, apply appropriate repellent when outside, repair holes in window screens and reduce the amount of standing water around your home. West Nile infection can be prevented when precautions are taken.”  According to health officials, mosquito counts have been rising rapidly in Weld County, particularly in Greeley, Evans, Fort Lupton and Milliken. The health department began monitoring adult mosquitoes on June 7 by trapping them at 24 locations in the county. None of the mosquitoes sent to the Colorado Department of Public Health and Environment have tested positive for West Nile virus.  To combat the recent surge in mosquitoes, Greeley city crews sprayed the route of today’s Stampede Independence Day Parade on 10th Avenue from 22nd Street to 3rd Street.  Last year, Colorado had 103 human cases of West Nile, and three of those people died. Weld County had 15 cases confirmed last year and no deaths.
