Health officials issue West Nile warning

Cook County health authorities are reminding residents to take precautions since West Nile virus season is almost here.

The virus is transmitted by mosquitoes that get it from infected birds.

The mosquitoes are worst in hot, dry weather. Recent summers have been cool and damp which means fewer cases of West Nile.

Authorities expect to see infected mosquitoes and birds in the next few weeks. People should cover their skin and use mosquito repellent when outside after dusk.
