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.

本完整COVID-19数据集汇聚了由Our World in Data维护的COVID-19数据，该数据集在整个COVID-19疫情期间持续更新。其内容涵盖确诊病例与死亡病例、住院、重症监护病房（ICU）入院、COVID-19检测以及COVID-19疫苗接种等方面的信息。确诊病例与死亡病例：此类数据源自世界卫生组织（WHO）冠状病毒仪表板，数据集每日更新。注1：时间/日期戳反映了数据上次由WHO更新的时间。由于处理和验证数据所需的时间，从报告至WHO至仪表板更新之间存在延迟。注2：在此之后进行的计数和更正将传递至下一个特定区域的报告周期。任何特定国家、地区或区域的延迟报告可能导致多日合并计数，并对前几日的计数进行回顾性更新，以准确反映趋势。WHO发现的或报告的重大数据错误可能以更频繁的间隔进行更正。住院与重症监护病房（ICU）入院：我们的数据源自官方来源，并由Our World in Data整理。各国来源的完整列表可在此查阅。COVID-19检测：此类数据由Our World in Data团队从官方报告中收集；您可以在我们关于COVID-19检测的帖子中找到更多详细信息，包括理解检测数据的问答清单、地理和时效覆盖范围的信息以及各国详细的来源信息。2022年6月23日，我们停止向COVID-19检测数据集添加新数据点。更多详情请参阅相关内容。针对COVID-19的疫苗接种：此类数据由Our World in Data团队从官方报告中收集。其他变量：我们的数据来源于多种渠道（联合国、世界银行、全球疾病负担、布拉瓦尼克政府学院等）。更多详细信息可在我们的代码簿中找到。
