Public Health Approach
Problem Response
Surveillance:What is the
problem?
Risk FactorIdentification:What is the
cause?
InterventionEvaluation:
Whatworks?
Implementation:How do you
do it?
Public Health Surveillance
Ongoing, systematic collection, analysis, and interpretation of health-related data essential to the planning, implementation, and evaluation of public health practice, closely integrated with the timely dissemination of these data to those responsible for prevention and control.
Public Health Surveillance
Systematic, ongoing Collection Analysis Interpretation Dissemination Link to public health
practice
Purposes of Public Health Surveillance
Assess public health status Define public health
priorities Evaluate programs Stimulate research
Surveillance
Information for Action
Uses of Public Health Surveillance
Estimate magnitude of the problem Determine geographic distribution of illness Portray the natural history of a disease Detect epidemics/define a problem Generate hypotheses, stimulate research Evaluate control measures Monitor changes in infectious agents Detect changes in health practices Facilitate planning
