Surveillance in epidemiology refers to the active systematic collection and analysis of data related to diseases or conditions in a population to inform public health actions.
In epidemiology, surveillance may be either active or passive:
- passive surveillance: collection of data from established reporting systems
- active surveillance: proactive search for cases of a disease
Surveillance need not involve directly diagnostic data. Over the last few decades, methods, sometimes based on machine learning, have appeared that use digital data created by a population such as internet searches 1,2 or even Twitter tweets 3.
In some countries, radiologists are directly involved in disease surveillance programs e.g. hepatocellular carcinoma surveillance.
NB: The term surveillance is often, but not always, used differently in radiology reports to imply the follow up of a pathological finding.
