Notification Rate of Hepatitis B per 100,000 population, 2015 to 2020
Rates are not available per 1,000 population, however they are available per 100,000 population.
Hepatitis B cases are notified as either: newly acquired, where evidence was available that the infection was acquired within 24 months prior to diagnosis; or unspecified, where the infection was acquired more than 24 months prior diagnosis or the period of infection is unspecified.
Determination of a case as newly acquired is reliant on public health follow-up and the availability of previous serology test results, with the method and intensity of follow-up varying by jurisdiction and over time. This makes interpretation of incidence using only notification data difficult. For the purposes of this indicator notification rates for both unspecified and newly acquired hepatitis B are presented in the table below and represent prevalence as a surrogate for incidence.
It is important to recognise that for hepatitis B infections, notifications to the National Notifiable Disease Surveillance System (NNDSS) represent only a proportion of the total cases and may be influenced by changes to testing patterns.
