To induce a patient to be examined often requires weeks or months of effort and persuasion. The less the apparent necessity, the more difficult it often becomes. If a person has no symptoms he will not go, and if he has symptoms, he is afraid to go, to a physician. Therefore, whenever it is possible to get exposed persons examined, well and good; when this is not possible, the nurse may confine her efforts to those with suspicious symptoms. One of the foremost requisites in this work is the ability to distinguish between essentials and unessentials, and having made the distinction, to concentrate on the most important. =Taking Patients to Dispensaries.= Unless the nurse has abundance of time and a very light district, it is not well that she should spend time in taking reluctant patients to a dispensary for examination. To do this, means to give up from one to several hours, which she can ill afford to spend in this manner. Nor is it necessary to waste her expert service in this way—it is always possible to find some one willing to take these patients, some friendly visitor, settlement worker, or even a kindly, intelligent neighbour. =Children.= It is conceded nowadays that people usually become infected with tuberculosis in the first ten or twelve years of life, or during childhood. The disease itself may or may not develop in later life, according to the circumstances or environment in which the individual is placed. It may light up later, if his resistance becomes lowered, or he is reinfected, and cannot carry the extra load. For this reason, it is a vastly important thing to protect children from infection, as well as to protect those exposed in childhood from later undue strain. The children the nurse sees are usually those in contact with a tuberculous father or mother. What is gained if we teach the parent to sleep alone, and spend part of the time away from them, yet permit him at other times to remain in close contact with the children? Intermittent contact, repeated often enough, is as bad as constant contact. If a mother nurses, feeds, cooks for, and handles her child, there are untold opportunities of infection. If the parent is intelligent and unselfish, it may be possible to bring about a relative degree of carefulness, and a minimum exposure, but there is no such thing as adequate carefulness while these conditions continue. Among the very poor, where it is impossible to regulate living conditions, there is practically no doing away with the danger of infection.
