West Nile turns up in north suburbs

Mosquito samples recently collected by the Evanston Department of Health and Human Services have tested positive for West Nile. That sample is the second collected in Illinois so far this year.

Officials say the virus will likely spread in the coming weeks as temperatures continue to heat up.

West Nile is transmitted by mosquitoes that pick up the virus by feeding on infected birds.

Only about 2 in 10 people bitten by an infected mosquito may experience West Nile symptoms.
