Thorough isolation also implies that the nurse shall frequently bathe and disinfect her person and her clothing, and that the sick-room itself shall be carefully dusted with a moist cloth and disinfected from time to time. The Contagious Sick-Room.--The contagious sick-room will be prepared in exactly the same way as the ordinary sick-room which has been previously described. In addition, however, it will be safeguarded in the following manner. A wet sheet will be hung up outside the door. This sheet will be kept constantly moistened with a solution of chloride of lime. One-half pound to an ordinary house-pail of water is the strength of the solution to use. Every window must be effectively screened to prevent the ingress and egress of flies and other insects. Conduct and Dress of the Nurse.--She will remain in the sick-room all the time unless when she takes outdoor exercise. Her dress will consist of a long gown which will entirely cover her person from the neck to the shoes and will be of plain, white, easily washed material, without tucks or ruffles or adornment of any kind. She should wear an ordinary pair of house slippers made of light leather. Her cap will be large enough to cover and include her hair and head. When she leaves the room, she will remove her cap, gown, and slippers, disinfect her hands in a disinfecting solution and wash her face, neck, and hands in soap and water. She should go directly out and in, without coming in contact with any occupant of the home. Feeding the Patient and Nurse.--The meals for the patient and nurse should be left on a table outside the door of the sick-room, from which place the nurse will then take them into the room. The utensils used for these meals should not be used by other members of the family during the entire sickness. After the patient and nurse have eaten, the utensils should be placed in a chloride of lime solution for disinfection. If any of the food is left over it should be put into a jar in which it may be disinfected and rendered harmless before being disposed of. How to Disinfect the Clothing and Linen.--All bed and body linen, towels, handkerchiefs, napkins, etc., should be immediately put into a large receptacle--a wash boiler, or tub, will answer the purpose admirably--containing a five per cent. solution of carbolic acid in which an adequate quantity of soft soap has been dissolved. They should remain in this mixture for two hours, after which they may be wrung out and taken to the laundry. How to Disinfect the Urine and Feces.--The urine and the stools should be passed into vessels containing a solution of four ounces of carbolic acid to the gallon of water. This vessel should be covered and the mixture allowed to stand for one hour, after which time it may be thrown out.
