have radically changed in recent years. Modern knowledge requires concurrent disinfection, or the destruction of germs from the moment when symptoms are first noticed; all the time, day and night, this disinfection must go on with unremitting care. Today wet sheets are not hung in doorways nor are chemicals left about in open dishes to disinfect quite harmless air, but scrupulous cleanliness at all stages of disease is recognized as one of the most important measures, if not the most important measure, in disinfection.
