Our World in Data COVID-19 Dataset

The complete COVID-19 dataset is a collection of the COVID-19 data maintained by Our World in Data that is updated throughout the duration of COVID-19. It includes information related to confirmed cases and deaths, hospitalization, intensive care unit admissions, testing for COVID-19, and vaccination for COVID-19.Confirmed cases and deaths: this data is collected from the World Health Organization Coronavirus Dashboard. The cases & deaths dataset is updated daily.Note 1: Time/date stamps reflect when the data was last updated by WHO. Due to the time required to process and validate the incoming data, there is a delay between reporting to WHO and the update of the dashboard.Note 2: Counts and corrections made after these times will be carried forward to the next reporting cycle for that specific region. Delayed reporting for any specific country, territory or area may result in pooled counts for multiple days being presented, with a retrospective update to counts on previous days to accurately reflect trends. Significant data errors detected or reported to WHO may be corrected at more frequent intervals.Hospitalizations and intensive care unit (ICU) admissions: our data is collected from official sources and collated by Our World in Data. The complete list of country-by-country sources is available here.Testing for COVID-19: this data is collected by the Our World in Data team from official reports; you can find further details in our post on COVID-19 testing, including our checklist of questions to understand testing data, information on geographical and temporal coverage, and detailed country-by-country source information. On 23 June 2022, we stopped adding new datapoints to our COVID-19 testing dataset. You can read more here.Vaccinations against COVID-19: this data is collected by the Our World in Data team from official reports.Other variables: this data is collected from a variety of sources (United Nations, World Bank, Global Burden of Disease, Blavatnik School of Government, etc.). More information is available in our codebook.

完整新型冠状病毒肺炎（COVID-19）数据集是由我们的世界在数据（Our World in Data）维护并在新冠疫情全程持续更新的COVID-19相关数据集合，涵盖确诊病例、死亡病例、住院治疗、重症监护病房（Intensive Care Unit，ICU）收治情况、新冠病毒检测及新冠疫苗接种相关信息。
确诊病例与死亡病例：本部分数据源自世界卫生组织（World Health Organization，WHO）新冠疫情数据仪表盘，病例及死亡数据集每日更新。注1：时间戳反映世界卫生组织完成数据更新的时刻；由于处理与校验传入数据需要耗时，向WHO上报数据与仪表盘更新之间存在一定延迟。注2：在此时间节点后完成的计数与修正，将顺延至对应区域的下一个报告周期。若特定国家、地区或领地存在延迟上报情况，可能会呈现多日合并后的统计数据，并通过回溯更新过往日期的计数以准确反映疫情趋势。检测到或上报至WHO的重大数据错误，将以更频繁的频次进行修正。
住院治疗与重症监护病房（Intensive Care Unit，ICU）收治情况：本部分数据源自官方渠道，并由我们的世界在数据进行整合汇总，各国家/地区的完整数据源列表可参见此处。
新冠病毒检测：本部分数据由我们的世界在数据团队从官方报告中采集获取，更多细节可参阅本团队发布的新冠检测相关文章，其中包含用于理解检测数据的问题清单、地域与时间覆盖范围说明，以及各国家/地区的详细数据源信息。本团队已于2022年6月23日停止向新冠检测数据集中添加新的数据点，更多相关内容可参见此处。
新冠疫苗接种：本部分数据由我们的世界在数据团队从官方报告中采集获取。
其他变量：本部分数据源自多类渠道（联合国、世界银行、全球疾病负担研究、布拉瓦茨基政府学院等），更多相关信息可参阅本团队的数据字典。
