Pandemic planning at the coal face: responsibilities of the public health unit.

Responding to an infectious disease pandemic requires a coordinated approach from all essential services. Public health units across NSW will play an important role in a range of control activities. These include: surveillance, education, communication, case ascertainment, case management (excluding clinical management), infection control, contact tracing, monitoring contacts in home quarantine, surveillance at borders, epidemiological studies and immunisation. Public health units are currently planning for such an emergency and these plans will need to be tested and refined under simulated conditions.
