Types of Methods used Bayesian Methods: A general tool to explicitly incorporate prior knowledge and fit more complicated regression models. Passive surveillance occurs when individual health care providers or diagnostic laboratories send periodic (in accordance with state or federal regulations) reports to the public health agency. ” 1 In the context of a Epidemiological surveillance is defined as the “ongoing systematic collection, analysis, and interpretation of health data that are essential to the planning, implementation, and evaluation of public health practice” (25). Last (ed)) Major Types of Uses of Public Health Surveillance Microsoft PowerPoint - Detels_surveillance. Decision-making phase • Knowledge of epidemiology of the disease is used to explore the various options available for its control • This often involves the modelling of the effects that these different options are likely to have on the incidence of the disease • These models can be combined with other models that examine the costs of the various control Types of Surveillance • Total (or Whole) House Surveillance • All HAIs are monitored in the entire population • Calculate rates for specific population (not an overall facility wide rate) • Targeted Surveillance • Particular care units • Infections related to medical devices Type of surveillance system. Surveillance is the backbone of any disease control program. Like other types of surveillance, VPD surveillance is vitally important for its potential to inform policy and monitor immunization programmes, including vaccine introduction, coverage and potential use for outbreak response. 3 National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention, CDC Epidemiology.

VPD surveillance is also able to detect Surveillance, Epidemiology, and Tracing. Although surveillance is most commonly used to guide the control and prevention of infectious disease, particularly through the detection of outbreaks, the principles and practice of surveillance are relevant to all domains of public health and ultimately can be considered as providing the evidence or information that The Centers for Disease Control and Prevention (CDC) defines public health surveillance as “ongoing, systematic collection, analysis, interpretation, and dissemination of data regarding a health-related event for use in public health action to reduce morbidity and mortality and to improve health” (CDC, 2001).
