This goal can be achieved in three ways: (a) by methods to improve host resistance of populations to environmental hazards; (b) by effective plans to improve the safety of the environment; and (c) by improving health-care systems designed to increase the likelihood, efficiency, and effectiveness of the first two goals. With respect to infectious diseases there are special elements within each of the three categories (Table 8-1). One might then view communicable diseases as an imbalance in the relationship of people and their environment which favors microbial dominance in populations.
