Although West Nile disease has declined markedly in Colorado, hunters who venture out for early September bird seasons should take precaution in areas where mosquitoes occur.
Nearly every species of birds acts as an intermediate carrier for the disease. Mosquitoes that bite birds then transfer the disease to humans.
West Nile reached a peak in Colorado in 2003, infecting 2,947 people, killing 63, most in the U.S. Infection declined to just more than 100 cases in 2004. This year, only 15 people have been stricken, but four occurred in recent weeks.
Hunters should take particular precaution in low-lying areas that breed mosquitoes. Many locations favored by dove and teal hunters, particularly east of the Continental Divide, are prime spots for the disease.
Repellents that contain a high percentage of DEET are effective in keeping mosquitoes at bay.
