This repository is the data archive from the COVID-19 tracking dashboard operated by the Johns Hopkins University Center for Systems Science and Engineering (JHU CSSE). Starting in January 2020 and running until March 2023, the team collected and published daily counts of confirmed COVID-19 cases, deaths, and recoveries for countries and regions around the world, along with county-level and state-level data for the United States. The data was compiled from dozens of official sources, national health ministries, the World Health Organization, the US CDC, European health agencies, and state and county health departments across the US, and organized into structured files that researchers, journalists, and developers could download and use freely. The repository served as the underlying dataset for the widely referenced JHU COVID-19 visual dashboard. As of March 2023, JHU stopped collecting new data; the repository now serves as a historical archive. Anyone doing research on pandemic trends, building retrospective models, or studying epidemiology would use this dataset to access the full time series of global COVID-19 case counts from 2020 through early 2023. The data is cited in peer-reviewed publications and requires attribution to the JHU CSSE team per their published guidelines.
