该数据集是约翰·霍普金斯大学系统科学与工程中心（JHU CSSE）发布的全球每日COVID-19数据集的存档版本，已于2023年3月9日停止主动维护并归档。数据集覆盖了从2020年1月22日至2023年3月9日的时间范围，以每日为频率，提供194个国家的国家级数据。数据内容包括累计确诊病例、累计死亡病例和累计康复病例，但康复数据在2021年后大多缺失，因此不建议作为目标变量使用。数据来源基于各国临时报告，定义、实验室标准和报告频率在不同国家和时间存在显著差异，应视为全球趋势信号而非可比比率。数据集仅包含国家级别数据，省/州级别数据因名称非标准化而被省略。访问方式为GitHub，许可证为CC-BY-4.0，层级为Tier 3。JHU CSSE COVID-19 — global daily (archived). This dataset is an archived version of the global daily COVID-19 data from the Johns Hopkins University Center for Systems Science and Engineering (JHU CSSE), with active maintenance stopped on 2023-03-09. It covers the period from 2020-01-22 to 2023-03-09, with daily cadence, and includes national-level data for 194 countries. Columns include cumulative confirmed cases, cumulative deaths, and cumulative recoveries, though recovery data is mostly NaN after 2021 and should not be used as a target. Data is compiled from ad-hoc national sources, with varying definitions, lab criteria, and reporting cadence across countries and over time, and should be treated as a global-shape signal rather than a comparable rate. Province-level data is dropped due to free-text names not conforming to ISO 3166-2. Access is via GitHub, licensed under CC-BY-4.0, and classified as Tier 3.
