NSW COVID-19 cases by likely source of infection (discontinued)

From 20 October 2023, COVID-19 datasets will no longer be updated.\r\nDetailed information is available in the fortnightly NSW Respiratory Surveillance Report: https://www.health.nsw.gov.au/Infectious/covid-19/Pages/reports.aspx.\r\nLatest national COVID-19 spread, vaccination and treatment metrics are available on the Australian Government Health website: https://www.health.gov.au/topics/covid-19/reporting?language=und\r\n\r\nCOVID-19 cases by likely source of infection. Publication of some data in this dataset has been suppressed (before 9 March 2020) or is being delayed because the risk of gaining information about an individual in the dataset increases as the number of cases decreases.\r\n\r\nThis dataset has been discontinued from 19 November 2021. NSW Health now reports daily COVID-19 cases as a total of local and overseas cases. With quarantine-free international travel, overseas origin of cases can no longer be determined immediately, but will be included in the NSW Health COVID-19 weekly surveillance reports.\r\n\r\nThe data is for confirmed COVID-19 cases only based on location of usual residence, not necessarily where the virus was contracted. The case definition of a confirmed case is a person who tests positive to a validated specific SARS-CoV-2 nucleic acid test or has the virus identified by electron microscopy or viral culture, at a reference laboratory. Data reported at 8pm daily.\r\n\r\nCase counts reported by NSW Health for a particular notification date may vary over time due to ongoing investigations and the outcome of cases under review thus this dataset and any historical data contained within is subject to change on a daily basis.\r\n\r\nThe underlying dataset was assessed to measure the risk of identifying an individual and the level of sensitivity of the information gained if it was known that an individual was in the dataset. The dataset was then treated to mitigate these risks, including suppressing and aggregating data.

自2023年10月20日起，新型冠状病毒肺炎（COVID-19）相关数据集将不再更新。详细信息可查阅每两周发布的《新南威尔士州呼吸道监测报告（NSW Respiratory Surveillance Report）》：https://www.health.nsw.gov.au/Infectious/covid-19/Pages/reports.aspx。最新的全国新冠疫情传播、疫苗接种及治疗数据可访问澳大利亚联邦政府卫生官网获取：https://www.health.gov.au/topics/covid-19/reporting?language=und

本数据集包含按可能感染来源分类的新冠确诊病例。2020年3月9日之前的部分数据已做隐匿处理，其余部分数据则因病例数越少，越易通过数据集反推识别个体信息，故延迟发布。

本数据集已于2021年11月19日起停用。新南威尔士州卫生部（NSW Health）目前将本地及境外输入新冠确诊病例合并发布。随着国际旅行无需检疫，无法即时判定病例的境外来源，但相关信息将纳入新州卫生部发布的新冠每周监测报告。

本数据集数据仅针对按常住地统计的确诊新冠病例，并非代表病毒实际感染地点。确诊病例的定义为：经参考实验室通过经过验证的特异性严重急性呼吸综合征冠状病毒2（SARS-CoV-2）核酸检测呈阳性，或通过电子显微镜、病毒培养分离出该病毒的人员。数据每日20:00完成上报更新。

由于持续的流行病学调查及在审病例的结果更新，新南威尔士州卫生部按通知日期统计的病例数可能会发生变动。因此本数据集及其中包含的所有历史数据每日均可能发生变更。

本原始数据集经评估，用于衡量识别个体的风险，以及若已知某个体纳入数据集时可获取的信息敏感度。随后对数据集采取了风险缓解处理措施，包括数据隐匿与数据聚合。
