OUTDOOR HAZARDS -- Officials in eastern Idaho’s Gem County say mosquitoes collected this week tested positive for West Nile virus. 

This follows a report in mid-August that the virus was found in a Mosquito near Yakima.

Idaho's Gem County Mosquito Abatement District director Jason Kinley says a small number of mosquitoes are infected. The district is treating any standing water that is producing mosquitoes and spraying to control adult mosquitoes.

 West Nile virus is a mosquito and bird disease. Animals and people can be infected when bitten by a female mosquito infected with the virus. 

Kinley says because it’s so late in the season, it’s not likely the virus will spread throughout the district before cold weather kills the insects.

According to the Center for Disease Control:

Most people bitten by a mosquito carrying West Nile virus show no symptoms, while about 10 percent develop West Nile fever. Less than 1 percent suffer an infected brain or spinal cord.
