Specific directions for disinfecting in every kind of communicable disease would be too extended to be given here. In each case the attendant should learn from the doctor just how that particular disease is communicated, just what discharges, utensils, linen, etc., need to be disinfected, and just what disinfectants he prefers to have used. The following general methods are now in use, but it must be remembered that from time to time new methods are devised and new disinfectants are discovered. CARE OF NOSE AND THROAT DISCHARGES.--The care of handkerchiefs has already been described on page 239. Cloths or cotton used to wipe the eyes or to receive any other bodily discharge including vomitus, should be collected in the same way and burned. Everyone should be taught in early childhood to cover the nose and mouth with a handkerchief during coughing and sneezing; if the patient has not already learned to do so he must be taught now. If the amount of expectoration is great, waterproof receptacles should be provided, which should be burned with their contents. CARE OF DISCHARGES FROM THE BOWELS AND BLADDER.--At the present time the following preparations are commonly used to disinfect stools and urine: 5% solution of carbolic acid; chloride of lime solution, made freshly whenever needed by mixing thoroughly ½ pound of chloride of lime with one gallon of water; and unslaked lime to which is added _hot_ water. The amount of carbolic solution used should be about equal in bulk to the amount of material to be disinfected; the chloride of lime solution should be at least twice, and the unslaked lime at least one-eighth the bulk. Fecal masses should be broken up so that the disinfectant may reach every part; they may be stirred with tightly twisted toilet paper, which should be left in the bedpan and disinfected with the stools. If these substances are used, disinfection is considered complete at the end of an hour, and the contents of the bedpan may then be emptied into the toilet with safety. It may be necessary to provide two bedpans so that one may be available for use while the contents of the other is being disinfected. Bedpans and urinals should be boiled daily and kept thoroughly clean at all times. In places having no sewerage system, disinfected discharges may be emptied into a trench situated at a distance from the well, and then covered with earth. As an extra precaution, the disinfected discharges may be mixed with sawdust or kerosene and burned in the trench. Directions for installing a sanitary privy may be found in Bulletin 68 of the United States Public Health Service. BATH WATER and water that has been used for cleansing the teeth and mouth may be disinfected in the same way as urine, or it may be emptied into a suitable receptacle and boiled ten minutes.
