Tetanus is a serious infection which can even be fatal. Tetanus germs (bacteria) live in the soil and dirt. The bacteria may get into your body through a cut or a wound in the skin. The bacteria make a poison (toxin) which causes the illness. Even small wounds such as a prick from a thorn can allow enough bacteria to get into the body to cause tetanus. The illness usually takes 7-8 days to develop but can vary from one day to two months. Therefore, you may have forgotten about a small cut before the illness starts.
However, if you can handle drying a basement on your own, heed the following suggestions: Pump out standing water. Use a wet/dry vacuum or submersible pump, rentable at Home Depot and other home improvement centers. At Home Depot, wet/dry vacs rent for $19 for four hours or $27 for 24 hours. A regular household vacuum won't do the trick, and using it might prove dangerous.
A damp mop will clean better than a dry one, but water is hard on some surfaces, such as wood. Microfiber mops come in both dry and wet varieties. And, although it may sound like overkill, Smallin says that if you dry mop your wood floors every day, you'll pretty much nip dust in the bud stage.
