The use of legislation as a health protection tool forms an important and distinct aspect in the arena of public health. A review of Hong Kong's infectious disease legislation was conducted with a view to updating the legal framework for the prevention of infectious diseases, in order to strengthen the capacity of law to support strategy in the control of infectious diseases. This article shares Hong Kong's experience in reforming its public health legislation to: (1) update terminology and re-organize provisions in accordance with modern public health disease control principles and control mechanisms for disease; (2) enhance responsiveness for better preparedness and flexibility in handling emergent infections; (3) ensure appropriate checks and balances to coercive powers; and (4) introduce emergency powers for the handling of public health emergencies.
