=Prevention of contagion= consists in isolating the patient; in disinfecting everything that has been in contact with him; in anointing the patient’s body with an antiseptic oil until desquamation is complete; and in thoroughly disinfecting the room after the patient’s removal. =Management.=—Have the patient, if possible, in a large, airy room, preferably at the top of the house. Keep the temperature uniform and the room well ventilated. Wear a loose wrapper and cap, and leave these inside the room when obliged to leave it. With cloths moistened with a 3 per cent. solution of carbolic acid wipe the floor, furniture, sills, door-knobs, mantelpiece, etc., once a day, but never dust or sweep. Thoroughly disinfect the secretions of the patient and all articles used by him before they leave the room. Allow the patient no food except what has been ordered, which will usually be milk, koumiss, junket, fruit-juices, and gruels. Encourage the patient to drink water freely. Apply to the body, at least once a day, a bland ointment. Note temperature, respiration, pulse, stools, quantity of nourishment, sleep, and effect of baths and medicine as in typhoid fever. Note especially the quantity and appearance of the urine, and have a sample in a clean bottle ready each day for the physician’s examination. Keep the nose and throat clean with mild antiseptic sprays or washes. Relieve pain in the throat, unless otherwise directed, with ice-poultices or hot-water compresses. MEASLES. Measles is an acute contagious disease characterized by moderate fever of about a week’s duration; by an eruption on the skin, appearing on the third or fourth day as small red spots that soon coalesce into crescentic blotches, remain three or four days, and then disappear with a branny desquamation; and by catarrhal symptoms involving the eyes, nose, and bronchial tubes (conjunctivitis, coryza, and bronchitis). The most common complications of the disease are catarrhal pneumonia, inflammation of the gastro-intestinal tract, and inflammation of the middle ear.
