Public Health Surveillance: monitoring the health of communities

Public health surveillance is the ongoing and systematic collection, analysis, and interpretation of data on specific health events. It is used to plan, implement and evaluate public health programmes.

General practitioners provide data and notifications on a variety of diseases, including notifiable diseases, influenza-like illness (ILI) and some respiratory illnesses.

Community and Public Health’s Surveillance Unit analyses this data and produces surveillance reports on:

  • notifiable diseases throughout the year (weekly and monthly);
  • viral respiratory diseases from May to October each year (weekly); and
  • epidemics or outbreaks of specific diseases as they occur or progress.
