The department says a pool of mosquitoes found near Polo tested positive for the virus. It's the department's first positive sample of 2019.

West Nile virus is transmitted through the bite of a Culex mosquitoes, commonly known house mosquitoes. The virus is picked up when mosquitoes feed on an infected bird.

The department says common symptoms for the virus include fever, nausea, headache and muscle aches. Symptoms may last from a few days up to a few weeks.

Four out of five people infected with West Nile virus will not show any symptoms, according to the department.

Ogle County says you can take several precautions to avoid the virus, including keeping doors and windows shut, repelling outdoors and reporting locations that may produce mosquitoes.

The department says maintaining vigilance to prevent exposure is extremely important.
