ESR’s internationally renowned experts collect, collate and analyse data and intelligence on a wide range of diseases present in New Zealand.

Our public health surveillance involves the ongoing, systematic collection, analysis, and interpretation of data on specific health events for use in the planning, implementation and evaluation of public health programmes. This extensive surveillance allows us to identify and characterise individual strains and cases of disease, track any changes in them, and to detect outbreaks and assess the effectiveness of control measures, including vaccines.

ESR manages the Notifiable Diseases Database (external link) , and uses this information, along with our reference laboratory information and the information collected from laboratories, to analyse data and provide intelligence on a wide range of diseases including measles, influenza, gastroenteritis, hepatitis and meningococcal disease. Other non-notifiable diseases that ESR undertakes surveillance for are influenza-like illnesses and sexually transmitted infections as well as laboratory surveillance of pathogens of public health importance.

Much of this work is undertaken under our agreement with the Ministry of Health and allows us to support our clients to predict where possible, prepare for, identify, respond to actual and potential human biosecurity and public health threats.

Laboratory-based health surveillance

ESR undertakes laboratory-based surveillance of communicable diseases and pathogens of public health importance. For this surveillance, diagnostic laboratories throughout New Zealand refer specimens or bacterial isolates from their patients to ESR's national reference laboratories for strain identification and epidemiological typing.

Patient specimens and bacterial isolates from the communicable diseases and pathogens listed below should be referred routinely by diagnostic laboratories to the relevant ESR laboratory for typing/surveillance purposes (this does not include specimens for diagnostic testing, nor for requests on a fee for test basis).

Please use a test request form (external link)  to submit a specimens or bacterial isolate to ESR.
