Immediately a mother discovers symptoms of contagious disease in her child she must quarantine the little patient, no matter what sacrifice this may entail on herself or on other members of the household. The room should be located in a remote corner of the house, provided this is one of the big, old-fashioned homes which are peculiar to the suburban or country town. In a smaller house or in an apartment it should be the most quiet room and the one farthest removed from family activities. This insures quiet for the patient, and less danger of contagion for the other members of the family. The room should be sunny and well ventilated. For some contagious diseases it is not necessary to strip the room to what may be termed hospital conditions. Doctors hold that measles and whooping-cough cannot be carried on fabrics; but the germ of scarlet fever has been known to live in hangings, rugs, and clothing for many months, even years. So, after all, as the change involves little trouble, it is just as well to take up carpets, and remove the hangings and curtains. Washable rugs may be used. The bureau should be stripped of fancy fittings to make room for the practical equipment required by the nurse. There should be no upholstered furniture, especially with scarlet fever; and the cushions used on wicker or wooden chairs should be covered with washable material. There should be a screen to surround the bed while the room is being aired; and, above all things, the bed must be so placed that the sun will not strike in the child’s eyes at any time. There should be a comfortable cot for the mother or trained nurse or member of the family assigned to the care of the invalid. No visitors or other members of the family should be admitted. Their presence cannot lessen the danger of the child, and it may endanger their lives and the lives of other people. If possible, there should be separate dishes, and a complete outfit for rinsing out clothing in this room. If the room is small these conveniences should be placed in an adjoining room which, like the sick room, should be barred to other members of the family. Remember that some contagions can be carried on cotton clothes. The mother’s or the nurse’s outer garments, aprons, towels, and bedding, all should be soaked in a solution of carbolic acid—one-half ounce to each gallon of water—before they are sent any place else to be laundered. After they have been soaked in this solution they can be washed by any one without danger of contagion. Nevertheless, it is better to have all the laundry work done separately.
