The best way to prevent the spread of disease (colds, flu and the creeping crud) is to wash your hands! Ever notice that the good doctor washes his/her hands before and after they examine you? The article quotes the fecal/oral route for transmision of this type of virus. So, wash your hands after using the bathroom. Wash your hands whenever you have the chance and I bet you will notice a decline in the number of sick days you have. In general you can disinfect any hard surface just by normal cleaning. Lysol is good because all you really need to do is wet the area and let it dry. Staying healthy is really pretty easy.
