Quizplus · Accepted Answer

Active surveillance systems use trained staff to actively identify and collect information on cases, rather than relying on passive reporting from hospitals and clinics. This involves reviewing patient records, indexes, vital records, and hospital logs to ensure complete case ascertainment. This method is considered more effective than passive reporting, as it reduces the likelihood of missing cases. However, it is also more resource intensive and therefore less commonly used in all 50 states.
