Upward trends in the incidence of other notifiable diseases — for example, tuberculosis, sexually transmitted infections and bloodborne viruses — can be managed by less-rapid responses.

The NNDSS is a dynamic tool of great value in specific diseases, particularly when control or elimination programs are being implemented, such as for hydatid disease, polio and measles. Diseases and conditions can be added or removed as required by the need for public health action.

Prevalence in many Indigenous communities is 15% or greater, and laboratory records indicate that the infection…
