COVID-19 Data Visualization

About This Page

This page hosts several visualizations of near real-time COVID-19 confirmed data, using several different metrics and plot types. Automated updates are posted every few hours, and final daily numbers are valid at 9:00 PM EDT (0100 UTC).

The data used is from Johns Hopkins CSSE prior to March 18th, and from Worldometers from March 18th onwards. Test and hospitalization data is from The COVID Tracking Project.

Several limitations of these data include:
(1) These are only plots of confirmed case data, which is a function of many variables, including how much testing is being done. There are likely many unconfirmed cases due to a variety of reasons, such as mild or no symptoms and a lack of access for testing.
(2) Both data sources occasionally show case numbers for a state or country decreasing the next day compared to the last day.
(3) Some countries and US states occasionally report a combination of new daily cases or deaths with previously unreported cases or deaths. For daily data, when possible and when sources are available, the previously unreported data have been removed such that only new daily data are included. If no sources are available and the data is a clear outlier, the average of the preceding and following day is taken to ensure continuity for overall daily trend data.
(4) France's data from April 2nd through May is from official government sources, removing previously unreported cases and deaths (Source).

COVID-19 Data will be displayed for high-impact hurricanes in my new Real-Time Tropical Cyclones page.

June 30, 2020: The data used in this site was revised last night to account for discrepancies. Internationally, daily data in the UK & Chile were changed to Johns Hopkins CSSE as Worldometers daily data for those countries was biased too high. In the US, cumulative & daily data for NY, NJ, CA, IL, KS, PA, OH, TX, and WA was applied from Johns Hopkins CSSE, while daily new cases for NY were obtained via The COVID Tracking Project as its numbers are consistent with official NY state data, and lacks the daily discrepancies that Johns Hopkins CSSE has.
