The Grundy County Health Department announced Friday that it has once again had mosquitoes test positive for West Nile Virus, this time in Morris.

These mosquitoes were collected on Wednesday, June 17.

The health department urges residents to take preventative measures seriously to avoid contracting West Nile Virus or other mosquito-borne illnesses.

The county health department recommends the following precautions:

• Make sure doors and windows have tight-fitting screens.

• Each week, eliminate or refresh all sources of standing water, such as bird baths, ponds, flower pots and containers.

• Wear shoes, socks, long pants and light-colored, long-sleeved shirts when outdoors.

• Use insect repellent containing DEET, IR3535, picaridin or oil of lemon eucalyptus.

• Report locations containing water that has been sitting stagnant for more than a week, such as roadside ditches and flooded yards.
