Notifiable Diseases and Hazardous Substance Injuries

Health practitioners are legally required to report to the Medical Officer of Health any cases of:

  • Notifiable diseases (section 74 Health Act 1956) or;

  • Hazardous substance injuries (section 143 Hazardous Substances and New Organisms Act 1996).

 

Why notify?

Notification allows public health services to collect, analyse and act on information to reduce the risk of disease in the public. Notifications allow us to:

  • Contact trace people to provide advice, prophylaxis, immunisation, isolation or quarantine

  • Identify environmental health issues e.g. contaminated drinking water

  • Identify disease sources e.g. foodborne illness

  • Detect and manage outbreaks

  • Monitor immunisation efficacy

  • Provide information to advocate for improved public health at a local or national level 

 

Who should notify?

  • Any health practitioner involved in the case is legally required to notify

  • It is an offence under the Health Act not to notify
