Not illustrated. 1918 edition. Excerpt: ...resolves itself into tolerance, and people who think themselves immune to malaria are sometimes surprised when the organisms are shown to be present in their blood. This means that they are not really immune to the disease in question, Deere. a.s in irant.hihty fcfl diphtheria. d(c) ) t 0 /o S 0 /o 2 S % Fio. 53.--Diagram showing relative susceptibility of children and adults to diphtheria. (From data in Health News) but that they can tolerate the organisms. The relative immunity of adults is often traced to missed or forgotten cases in childhood; children, too, come into closer contact with each other and are less particular about handling things in a sanitary way, which also helps account for the so-called partial immunity of adults to children's diseases: so that all statements regarding immunity must be weighed carefully before acceptance. Racial or other predisposition to disease often resolves itself into increased opportunities for infection, lessened resistance because of unsanitary homes or insufficient food, etc. i Predisposing Factors.--Hunger, worry, alcoholic excess, overwork, and overexposure are predisposing factors to disease; for example, chickens are quite immune to tetanus, but it has been shown by experiment that if a chicken is chilled, it succumbs to the inoculation of a small amount that otherwise would not affect it. TREATMENT AND PREVENTION In the preceding paragraphs we have spoken as if recovery always followed an attack of any disease--as if the white corpuscles and the antibodies always increased at a sufficiently rapid rate to prevent a deadly accumulation of bacteria and their toxins. Unfortunately, this is not true, and bacteria and their irritating products often multiply much more.show more
