Monitoring often used interchangeably with surveillance but lacks the action component. Identify health status of populations: acute changes in disease occurrence and distribution, outbreaks, epidemics: support disease investigation and control, find cases, isolates of infectious agents, support recall of implicated foods. Wait for cases to be reported to you. Active surveillance: actively go out and search for cases: often occurs during outbreak situations, reminders to data providers, costly, typically limited to rare diseases, sentinel programs, research studies . Desire completeness: increases number of reported cases. Relies on a pre-arranged sample of reporting sources who agree to report all the cases. Completeness is sacrificed greater reliability and speed less cost good for common diseases. Detailed information and sampling from sentinel site.
