When the patient is fully convalescent and all desquamation has ceased, cleanse him thoroughly with a warm bath and soap for four successive days. If at the end of that time no roughness of the skin remains, he may be dressed in clean clothes and taken from the room, for he is no longer a source of danger. The room itself and the furniture are then to be thoroughly cleansed and disinfected. The ceiling and walls, if of ordinary hard finish, are to be scraped and whitewashed. All woodwork should be rubbed with damp cloths and the floor well scrubbed. Care should be taken to remove all dust from the ledges over windows and doors. All the cloths used in this cleansing process are to be burned. If these directions have been carefully carried out, there is no need for further disinfection. But if upholstered furniture has been allowed to remain in the room, or other articles which cannot be burned or scrubbed or soaked in the zinc solution, it may be desirable to attempt to disinfect the whole room and its contents by means of chlorine or sulphurous acid gases. Of these, sulphurous acid gas is the cheapest, and upon the whole the best, but it must be used in large quantity, and for a longer time than is customary, if it is to be relied upon. For this purpose all openings into the room should be closed, and pillows, mattrasses, upholstered furniture, and articles which cannot be treated with the zinc solution should be opened, so that they may be exposed throughout to the fumes. The sulphur should be burned in an iron pan or pot, placed in a tub containing water or upon a large surface of sand. About 18 ounces of roll sulphur should be used to each 1000 cubic feet of space, and after twenty-four hours 12 ounces more should be burned and the room be then closed for twenty-four hours longer, after which it may be opened and aired. In case of death the body should at once be wrapped in a sheet thoroughly soaked with the chloride of zinc solution, and either be placed in an air-tight coffin at once or be buried without delay. The funeral should be strictly private, and the sheet referred to should not be disturbed or the body exposed to view. The cases most liable to spread the disease are those in which the attack is very light and the child is not confined to its bed. It is desirable that children in a house in which there are cases of scarlet fever should not be allowed to attend school or mingle with other children who have not had the disease.
