Mosquitoes in DuPage County recently tested positive for the West Nile Virus.

Typically, only one in five people infected with the mosquito-borne illness actually feels sick.

Some symptoms include fever, headache, body aches, vomiting or a rash.

Officials said people should wear insect repellent, remove sitting water on your property, and avoid being outside during dusk and dawn when mosquitoes are most active.
