The Sacramento-Yolo Mosquito & Vector Control District says a total of two mosquitoes and seven birds have been found in Wilton, Elk Grove and Citrus Heights.

 Ground-fogging has been conducted in Wilton and at C-Bar-C Park in Citrus Heights.

The district says the cool weather has helped keep the number of infections  at a relatively low level.

Combined, 25 birds and mosquitoes have tested positive for West Nile this year.
