Warning Johns Hopkins University has stopped publishing on confirmed COVID-19 cases and deaths. We have replaced the entire time series with WHO’s weekly-updated data. This change will not affect users of our charts and dataset. Read more.
Our complete COVID-19 dataset is a collection of the COVID-19 data maintained by Our World in Data. We will update it daily throughout the duration of the COVID-19 pandemic (more information on our updating process and schedule here). It includes the following data:
| Metrics | Source | Accessed/Updated* | Countries |
|---|---|---|---|
| Vaccinations | Official data collated by the Our World in Data team | Daily | 218 |
| Tests & positivity | Official data collated by the Our World in Data team | No longer updated (read more: #2667) | 193 |
| Hospital & ICU | Official data collated by the Our World in Data team | Daily | 46 |
| Confirmed cases | WHO COVID-19 Data | Daily | 219 |
| Confirmed deaths | WHO COVID-19 Data | Daily | 219 |
| Reproduction rate | Arroyo-Marioli F, Bullano F, Kucinskas S, Rondón-Moreno C | Daily | 196 |
| Policy responses | Oxford COVID-19 Government Response Tracker | Daily | 185 |
| Other variables of interest | International organizations (UN, World Bank, OECD, IHME…) | Fixed | 242 |
A specific section of this repository is also dedicated to vaccinations, with a lighter dataset containing only vaccination data.
*By Accessed we mean that we have accessed the source's data. It does not imply that the data in the source is changed.
- 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.
Our complete COVID-19 dataset is available in CSV, XLSX, and JSON formats, and includes all of our historical data on the pandemic up to the date of publication.
The CSV and XLSX files follow a format of 1 row per location and date. The JSON version is split by country ISO code, with static variables and an array of daily records.
The variables represent all of our main data related to confirmed cases, deaths, hospitalizations, and testing, as well as other variables of potential interest.

A full codebook is made available, with a description and source for each variable in the dataset.
Prior to 8 March 2023 we relied on Johns Hopkins University for confirmed cases and deaths (we now use WHO's data). Our dataset as it was on that date can be downloaded here.
If you are interested in the individual files that make up the complete dataset, or more detailed information, other files can be found in the subfolders:
latest: shortened version of our complete dataset with only the latest value for each location and metric (within a limit of 2 weeks in the past). This file is available in CSV, XLSX, and JSON formats.cases_death: data from the COVID-19 dashboard by the WHO, related to confirmed cases and deaths.testing: data from various official sources, related to COVID-19 tests performed in each country. This folder contains two files with more detailed information:covid-testing-all-observations.csvincludes, for each historical observation, the source of the individual data point, and sometimes notes on data collection;covid-testing-latest-data-source-details.csvincludes, for each country in our testing dataset, the latest figures and a detailed description of how the country’s data is collected;
excess_mortality: data on excess mortality during the pandemic, sourced from the Human Mortality Database and the UK Office for National Statistics;vaccinations: data from various official sources, related to COVID-19 vaccinations in each country;archived: data from other providers that we've stopped using and updating;internal: data extracts intended for internal use at Our World in Data. They may change or be deleted without notice so we discourage using them.
- Up until 17 March 2020, we were using WHO data manually extracted from their daily situation report PDFs.
- From 19 March 2020, we started relying on data published by the European CDC. We wrote about why we decided to switch sources.
- On 3 April 2020, we added country-level time series on COVID-19 tests.
- On 16 April 2020, we made available a complete dataset of all of our main variables related to confirmed cases, deaths, and tests.
- On 25 April 2020, we added rows for "World" and "International" to our complete dataset. The
iso_codecolumn for "International" is blank, and for "World" we useOWID_WRL. - On 9 May 2020, we added new variables related to demographic, economic, and public health data to our complete dataset.
- On 19 May 2020, we added 2 variables related to testing:
new_tests_smoothedandnew_tests_smoothed_per_thousand. To generate them we assume that testing changed equally on a daily basis over any periods in which no data was reported (as not all countries report testing data on a daily basis). This produces a complete series of daily figures, which is then averaged over a rolling 7-day window. - On 23 May 2020, we added a JSON version of our complete dataset.
- On 4 June 2020, we added a
continentcolumn to our complete dataset. - On 1 July 2020, we changed the format of the JSON version of our complete dataset to normalize the data and reduce file size.
- On 4 August 2020, we added the
positive_rateandtests_per_casecolumns to our complete dataset. - On 7 August 2020, we transformed our markdown codebook to a CSV file to allow easier merging with the complete dataset.
- On 17 August 2020, we added 4 variables related to cases and deaths:
new_cases_smoothed,new_deaths_smoothed,new_cases_smoothed_per_million, andnew_deaths_smoothed_per_million. These metrics are averaged versions (over a rolling 7-day window) of the daily variables. - On 10 September 2020, we added the
human_development_indexcolumn to our complete dataset. - On 14 October 2020, we added data on excess mortality during the pandemic in the
excess_mortalityfolder, sourced from the Human Mortality Database and the UK Office for National Statistics. - On 29 October 2020, we added data on hospitalizations and intensive care unit (ICU) admissions, sourced from the European Centre for Disease Prevention and Control (ECDC), who provide these statistics only for a select number of European countries, and update it on a weekly basis.
- On 10 November 2020, we added data on hospitalizations and intensive care unit (ICU) admissions for the United States, sourced from the COVID Tracking Project.
- On 13 November 2020, we added real-time estimates of the effective reproduction rate (R) of the virus, sourced from Arroyo Marioli et al. (2020).
- On 30 November 2020, we changed our source for confirmed cases and deaths to the COVID-19 Data Repository by the Center for Systems Science and Engineering (CSSE) at Johns Hopkins University. Our previous source for confirmed cases and deaths, the European Centre for Disease Prevention and Control (ECDC), had announced in November 2020 that it would switch from a daily to a weekly reporting schedule from December. Our World in Data therefore had to transition away from the ECDC as a source to continue to provide daily updates of confirmed cases and deaths. The format (variable names and types) of our complete COVID-19 dataset remains the same.
- On 9 December 2020, we changed the names of three countries in our files to match their recently-changed official names.
Czech Republichas becomeCzechia,Macedoniahas becomeNorth Macedonia, andSwazilandhas becomeEswatini. - On 16 December 2020, we started collecting country-level time series on COVID-19 vaccinations.
- On 18 December 2020, we added in the
latestfolder a shortened version of our complete dataset with only the latest value for each location and metric (within a limit of 2 weeks in the past). This file is available in CSV, XLSX, and JSON formats. - On 19 December 2020, we added data on hospitalizations and intensive care unit (ICU) admissions for Canada, sourced from the COVID-19 Tracker.
- On 6 January 2021, we added two variables for daily vaccinations to our complete dataset.
- On 7 January 2021, we replaced the United Kingdom's hospital and ICU data previously gathered by the European CDC with the official data published by the British government.
- On 26 January 2021, we added 4 variables on people vaccinated and people fully vaccinated to our complete dataset.
- On 4 February 2021, we added rows for Africa, Asia, Europe, European Union, North America, Oceania, and South America to our complete dataset. The
iso_codecolumn for these rows starts withOWID_. - On 5 March 2021, due to the COVID Tracking Project's announcement that their data collection effort would stop in March 2021, we transitioned to the Department of Health & Human Services as our source for data on hospitalizations and ICU admissions in the United States.
- On 15 July 2021, we added data on intensive care unit (ICU) patients for Algeria, sourced from the Ministry of Health.
- On 11 August 2021, we added the metric
total_boostersto our vaccination data. This counts the total number of booster doses (doses administered beyond the number prescribed by the vaccination protocol). - On 12 August 2021, we added hospital and ICU data for Switzerland, sourced from the Federal Office of Public Health.
- On 28 September 2021, we changed the way we estimate the excess mortality. More details here. We also added 3 new variables to our complete dataset:
excess_mortality_cumulative(cumulative % of excess deaths),excess_mortality_cumulative_absolute(cumulative count of absolute excess deaths),excess_mortality_cumulative_per_million(cumulative count of excess deaths per million people). - On 15 November 2021, we added the metrics
new_people_vaccinated_smoothedandnew_people_vaccinated_smoothed_per_hundredto our vaccination data. They count the daily number of people receiving their first vaccine dose. - On 27 December 2021, we added a specific folder for our hospitalizations & ICU data.
- Since 29 March 2022, vaccination data is no longer updated on a daily basis. Updates now are only on weekdays (Monday until Friday).
- On 10 March 2023, we changed our source for confirmed cases and deaths to the WHO COVID-19 dashboard. Our previous source for confirmed cases and deaths, the COVID-19 Data Repository by the Center for Systems Science and Engineering (CSSE) at Johns Hopkins University (JHU), had announced in February 2023 that it would no longer update their data from March 2023. Our World in Data therefore had to transition away from the JHU as a source to continue to provide daily updates of confirmed cases and deaths. The format (variable names and types) of our complete COVID-19 dataset remains the same.
- In rare cases where our source for confirmed cases & deaths reports a negative daily change due to a data correction, we set the corresponding metric (
new_casesornew_deaths) toNA. This also means that rolling metrics (7-day rolling average, weekly rolling sum, biweekly rolling sum) are set toNAuntil this missing value leaves the rolling window. - The population estimates we use to calculate per-capita metrics are based on the last revision of the United Nations World Population Prospects. The exact values can be viewed here. In a few cases, we use other sources (see column
sourcein the population file) when the figures provided by the UN differ substantially from reliable and more recent national estimates. Population estimates for a few subnational locations are taken from national reports, and are stored here. - We standardize names of countries and regions. Since the names of countries and regions are different in different data sources, we standardize all names to the Our World in Data standard entity names.
- We may correct or discard inconsistencies that we detect in the original data.
- Testing data is collected from many different sources. A detailed documentation for each country is available in our post on COVID-19 testing.
