I'm sure most people have been told by doctors to throw out your toothbrush after you've had strep throat. I decided that is good practice to throw it out after a virus, the flu, or any bacterial infection, so that you are not re-infecting yourself. It just makes good sense to me.

With cold and flu season coming along make sure to replace everyone's toothbrush after a bout of cold or something. (not overly frugal to keep replacing a toothbrush, but that is still cheaper then ongoing Dr. bills) some people say to just boil the toothbrushes also.
