ANS: B
Standardized definitions of diseases are necessary for public health monitoring and surveillance across all levels of government. Diseases are defined and classified according to confirmed cases, probable cases, laboratory-confirmed cases, clinically compatible cases, epidemiologically linked cases, genetic typing, and clinical case definition. Once defined, disease occurrence can be compared across time, populations, and geographic areas; and appropriate control efforts can be implemented.
