                Surveillance in public health is defined as ‘‘the on-                  the frequency of adverse events such as infection or
            going, systematic collection, analysis, interpretation,                   injury. Although the goal of contemporary infection
            and dissemination of data regarding a health-related                      prevention and control programs is to eliminate HAIs,
            event for use in public health action to reduce morbid-                   epidemiologic surveillance is still required for accurate
            ity and mortality and to improve health.’’1 Infection                     quantification of events and demonstration of perfor-
