The stale water and humid air makes the perfect breeding ground for bacteria.
The Winnebago County Health Department is providing tetanus shots and water testing kits for all those in need. The shots will also be available tomorrow but only by appointment.
Another big health concern Boone County officials say is mold, "Getting things cleaned up and dried as quickly as possible is important. If a house or anything in close place stays moist a long time you're going to have some mold."
The health department suggests using a mild bleach solution to clean up fungus or bringing in a professional cleaning service.
