Formerly, it was almost an article of faith that disinfection of rooms and houses which had been occupied by a person suffering from an infectious disease, and of the clothing with which he had been covered, or of anything in proximity to which he had been placed, should be undertaken as an ordinary preventive measure. This was regarded as more or less a safeguard against the spread of disease. Although, perhaps, the belief in terminal disinfection has wavered to some extent recently, the great majority of the medical profession here and in Europe still strongly recommends disinfection after the occurrence of a communicable disease.
