New cases (Notes)
- Dec 5: From November 21, 2020 through December 5,2020, Washington experienced a variety of technical difficulties and an increased laboratory report volume. On December 5, 2020, Washington reported 225,000 tests that were conducted through this time period.
- Dec 18: On December 18, 2020, we backfilled the timeseries of Probable Cases, Confirmed Cases, and Cases (Confirmed and Probable) from data provided on Washington’s dashboard on December 17, 2020. Since the data is by date of specimen collection, there is missing data for recent days.
- Dec 17: On December 16, 2020, Washington started including probable deaths in their death counts. We capture Washington’s date with a a one day lag. We assume that many of the 89 new deaths added on December 17, 2020 are are not from the most recent 24 hour period.
We calculate daily changes based on the data states report each day. Some states report new cases, tests, and deaths using other methods. Please consult official state data sources for more information. We chart “New tests” using different units across jurisdictions, because not all states and territories report tests in the same units. Learn more about total test units and see what we chart for each jurisdiction in our total tests documentation.
We do not have a complete dataset for every metric in every state. If we have data for less than 30% of the past 90 days for a given metric, you’ll see a warning instead of a chart for that metric.
All the data for these charts is available for download. You can also review tabular national data on our US historical data page and data for each state and territory on the individual state or territory’s overview page.

Race & ethnicity data
We compute the number of cases and deaths per 100k people for each race and ethnicity.
These numbers show the scale of outcomes compared to the size of each group’s population. These are not the number of cases or deaths, rather the proportion of each demographic group who have been affected.

Here's a snapshot of what the key COVID-19 metrics look like in Washington, DC as of today.
January 7, 2021
At publish time, we had no updates from 7 of the 56 states and territories we track: AR, CT, KS, MI, MP, RI, and WA. Seven additional states did not report current hospitalizations today: HI, MN, MS, NV, OK, OR, and WI.
January 3, 2021
Today's record death count includes a backlog of "roughly 200" deaths reported in WA. Even without this backlog, today's total would still be the highest to date.
December 31, 2020
WA revised their total test numbers down by 667k. The state's dashboard noted duplicate case counts and incomplete data from November 21 to December 16.
December 19, 2020
Today’s test number includes a backlog of about 226k tests from WA, which had not reported test encounters since Nov 22. We will try to get a time series to backfill the tests, but may not succeed.
