Surveillance case definitions
Health professionals use surveillance case definitions to decide whether to notify us of a case. The Communicable Diseases Network Australia (CDNA) develops surveillance case definitions.
Laboratory case definitions
The Public Health Laboratory Network (PHLN) is a group of laboratories that work together to provide services in public health microbiology.
It develops and publishes a list of laboratory case definitions to help diagnose and analyse nationally notifiable diseases.
PHLN laboratory staff use laboratory case definitions to determine if the disease is present in a sample.
Laboratory case definitions help ensure that pathology and laboratory resources are used efficiently for surveillance and responding to outbreaks of diseases of national concern.
