Passive Surveillance

Passive surveillance is the use of local healthcare services to collect data on disease incidence or adverse effects of medicines. It relies on staff and services, who are part of a reporting network, collecting data and generating reports. There is no active search for cases.

For example, passive surveillance is the most common method used to monitor the incidence of vaccine-preventable diseases so that national and international bodies can identify possible outbreaks and organise vaccine provisions.
