Complications and Sequels.—Severe bronchitis, pneumonia, croup, laryngitis, sore eyes, ear abscess and deafness, violent diarrhea, convulsions, and, as a late result, consumption sometimes accompany or follow measles. For the consideration of these disorders, see special articles in other parts of this work.
Outlook.—The vast majority of healthy patients over two years old recover from measles completely. Younger children, or those suffering from other diseases, may die through some of the complications affecting the lungs. The disease is peculiarly fatal in some epidemics occurring among those living in unhygienic surroundings, and in communities unaccustomed to the ravages of measles. Thus, in an epidemic attacking the Fiji Islanders, over one-quarter of the whole population (150,000) died of measles in 1875. Measles is more severe in adults than in children.
Diagnosis.—For one not familiar with the characteristic rash a written description of it will not suffice for the certain recognition of the disease, but if the long preliminary period of catarrh and fever, and the appearance of the eruption on the fourth day, be taken into account—together with the existence of sore eyes and hoarse, hard cough—the determination of the presence of measles will not be difficult in most cases.
Treatment.—The patient should be put to bed in a darkened, well-ventilated room at a temperature of 68° to 70° F. While by isolation of the patient we may often fail to prevent the occurrence of measles in other susceptible persons in the same house, because of the very infectious character of the disease, and because it is probable that they have already been exposed during the early stages when measles was not suspected, yet all possible precautions should be adopted promptly. For this reason other children in the house should be kept from school and away from their companions, and they ought not to be sent away from home to spread the disease elsewhere. The bowels should be kept regular by soapsuds injections or by mild cathartics, as a Seidlitz powder. If the fever is over 103° F. and is accompanied by much distress and restlessness, children may be sponged with tepid water, and adults with water at 80° F., every two hours or so as directed under scarlet fever. When cough is incessant or the rash does not come out well, there is nothing better than the hot pack.
The patient is stripped and wrapped from feet to neck in a blanket wrung out of hot water containing two teaspoonfuls of mustard stirred into a gallon of water. This is then covered with two dry blankets and the patient allowed to remain in the blankets for two or three hours, when the application may be repeated. It is well to keep a cold cloth on the head during the process. Cough is also relieved by a mixture containing syrup of ipecac, twenty drops; paregoric, one teaspoonful, for an adult (or one-third the dose for a child of six), which should be given in one-quarter glass of water and may be repeated every two hours. If there is hoarseness, the neck should be rubbed with a mixture of sweet oil, two parts; and oil of turpentine, one part, and covered with a flannel bandage. The cough mixture will tend to relieve this condition also. A solution of boric acid (ten grains of boric acid to the ounce of water) is to be dropped in both eyes every two hours with a medicine dropper. Although usually mild, the eye symptoms may be very severe and require special treatment, and considerably impaired vision may be the ultimate result. Severe diarrhea is combated with bismuth subnitrate, one-quarter teaspoonful, every three hours. For adults, the diet consists of milk, broths, gruels, and raw eggs. Young children living on milk mixtures should receive the mixture to which they are accustomed, diluted one-half with barley water. Nourishment must be given every two hours except during sleep. The patient should be ten days in bed, and should remain three days in his room after getting up (or three weeks in all, if there are others who may contract measles in the house), and after leaving his room should stay in the house a week longer. The principal danger after an attack of measles is of lung trouble—pneumonia or tuberculosis (consumption)—and the greatest care should be exercised to avoid exposure to the wet or to cold draughts.
GERMAN MEASLES (Rötheln).—German measles is related neither to measles nor scarlet fever, but resembles them both to a certain extent—more closely the former in most cases. It is a distinct disease, and persons who have had both measles and scarlet fever are still susceptible to German measles. One attack of German measles usually protects the patient from another. Adults, who have not been previously attacked, are almost as liable to German measles as children, but it is rare that infants acquire the disease. It is a very contagious disorder—but not so much so as true measles—and often occurs in widespread epidemics. The breath and emanations from the skin transmit the contagium from the appearance of the first symptom to the disappearance of the eruption.
Development.—The period elapsing after exposure to German measles and before the appearance of the symptoms varies greatly—usually about two weeks; it may vary from five to eighteen days.
Symptoms.—The rash may be the first sign of the disease and more frequently is so in children. In others, for a day or two preceding the eruption, there may be headache, soreness, and redness of the throat, the appearance of red spots on the upper surface of the back of the mouth, chilliness, soreness in the muscles, loss of appetite, watering of the eyes. Catarrhal symptoms are most generally absent, an important point in diagnosis. When present, they are always mild. These preliminary symptoms, if present, are much milder and of shorter duration than in measles, where they last for four days before the rash appears; and the hard, persistent cough of measles is absent in German measles. Also, while there is sore throat in the latter, there is not the severe form with swollen tonsils covered with white spots so often seen in scarlet fever. Fever is sometimes absent in German measles; usually it ranges about 100° F., rarely over 102° F. Thus, German measles differs markedly from both scarlet fever and measles proper. The rash usually appears first on the face, then on the chest, and finally covers the whole body, in the space of a few hours—twenty-four hours at most. The eruption takes the form of rose-red, round or oval, slightly raised spots—from the size of a pin head to that of a pea—sometimes running together into uniform redness, as in scarlet fever. The rash remains fully developed for about two days, and often changes into a coppery hue as it gradually fades away. There are often lumps—enlarged glands—to be felt under the jaw, on the sides and back of the neck, which occur more commonly in German than in true measles. The glands at the back of the neck are the most characteristic. They are enlarged in about two-thirds of the cases.
Determination.—The diagnosis or determination of the existence of measles must be made, in the absence of a physician, on the general symptoms rather than on the rash, which requires experience for its recognition and is subject to great variations in appearance, at one time simulating measles, at another scarlet fever.
German measles differs from true measles in the following points: the preliminary period—before the rash—is mild, short, or absent; fever is mild or absent; the cold in the nose and eyes and cough are slight or may be absent, as contrasted with these symptoms in measles, while the enlarged glands in the neck are more pronounced than in measles. The onset of German measles is not so sudden as in scarlet fever and not accompanied with vomiting as in the latter, while the sore throat and fever are much milder in German measles. The peeling, which is so prominent in scarlet fever with the disappearance of the rash, is not infrequently present. It may be absent. Its presence or absence seems to depend upon the severity of the eruption. The desquamation when present is finer than in either measles or scarlet fever.
