Hepatitis B incidence per 100,000 population

Notification Rate of Hepatitis B per 100,000 population, 2015 to 2020\r\n\r\nRates are not available per 1,000 population, however they are available per 100,000 population.\r\n\r\nHepatitis 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. \r\n\r\nDetermination 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.\r\n\r\nIt 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.\r\n\r\nFurther information can be found here > http://www9.health.gov.au/cda/source/cda-index.cfm \r\n\r\n

2015至2020年每10万人口乙型肝炎（Hepatitis B）报告发病率

目前暂无每1000人口的发病率数据，但可提供每10万人口的发病率数据。

乙型肝炎病例报告分为两类：其一为新感染病例，即有证据表明感染发生于确诊前24个月内；其二为感染时间未明确病例，即感染发生于确诊前24个月以上，或感染时间段未明确。

判定某一病例为新感染病例，需依托公共卫生随访追踪及既往血清学检测（serology test）结果的可及性，且追踪的方式与强度因辖区不同及时间推移而存在差异。这使得仅通过报告数据解读发病率（incidence）变得困难。本指标将未明确感染时间与新感染乙型肝炎的报告发病率均列入下表，以患病率（prevalence）作为发病率的替代指标。

需注意，向国家法定传染病监测系统（National Notifiable Disease Surveillance System, NNDSS）上报的乙型肝炎感染病例仅为总病例数的一部分，且可能受检测模式变化的影响。
