A public health nurse (PHN) is investigating an outbreak of salmonellosis in a community. Which type of surveillance system is being used?

a. Active
b. Passive
c. Sentinel
d. Special


ANS: A
In the active system, a PHN begins to search for cases through contacts in the community. The nurse names the disease and gathers data about existing cases to try to determine the magnitude of the problem. In the passive system, case reports are sent to local health departments by health care providers. In the sentinel system, trends in commonly occurring diseases or key health indi-cators are monitored. Special systems are developed for collecting particular types of data and may be a combination of active, passive, and/or sentinel systems.
