I would suggest getting an air purifier to get rid of any household germs, mold spores, cat dander (if this applies to you), dust, and any other spore that floats around your house. Make sure to get an air purifier with a TRUE HEPA filter. Not a HEPA TYPE filter or a carbon filter. You want TRUE HEPA, as they get rid of 99.9-100% of household nasties. And of course what Liza said - wipe down grocery cart handles, etc. I make a point not to touch public door handles, toilet handles, etc. Anything that I know someone else with a cold may have touched. And hand sanitizer is your best friend!<img src="i/expressions/face-icon-small-smile.gif" border="0">
