Current data quality grade
To help the public understand how well each state is performing, we have assigned each state a data-quality grade based on our assessment of the completeness of their reporting. Learn more

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 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.

Data as of November 19 2020
Alaska combines PCR and antigen tests in the total tests figure reported on the state's dashboard.
Negative test results reported in our API and CSVs are calculated by subtracting Positive from Total PCR tests (specimens) in the absence of better data.
On November 17, 2020, Alaska announced that “As of 11/17/2020, the cases dashboard will not be showing data on recovered and active cases due to the increasing State case load”. As a result, Alaska’s Recovered will no longer be updated.
On November 16, 2020 we updated the Positive field to include only residents. We also deleted the time series for Positive Cases (PCR) because Alaska is lumping PCR and antigen testing for their case definition.
On November 16, 2020 we added Cumulative Hospitalized (which includes both residents and non-residents), although the value does not reflect current hospitalizations.
On November 7, 2020, Alaska announced that their testing dashboard would be "temporarily disabled from November 6th to November 9th" and that testing data could be accessed through their data summary tables. After originally using the data summary tables on November 7th, we have reversed that decision, and reverted the values to their November 6th state. The frozen values were replaced on November 10, with values from the state's Tests Dataset.
On November 6, 2020, Alaska’s Total PCR tests (specimens) and Positive PCR tests (specimens) decreased without explanation. As a result, Negative PCR tests (people), which is calculated by subtracting Positive PCR tests (people) from Total PCR tests (specimens), decreased as well.
On November 5, 2020, Alaska’s Total PCR tests (specimens) increased from roughly 628k to 782k. We were unable to find an explanation for the increase.
As of September 18, 2020, Alaska's total test results are drawn from our
totalTestsViral field instead of calculated via positive+negative.

The New Mexico chart shows how much more likely ‘American Indian or Alaska Native’ people have been to test positive or die from COVID-19 since the pandemic began, compared to other people in the state.

Update for our data users - we continued to implement changes to our original totalTestResults API field, resulting in a ~600k cumulative test increase since March. We updated test totals for 14 states: AK, AL, AR, AS, CA, DC, GA, ID, KY, MN, NH, SD, VA, and WA.

We’d like to highlight Alaska for providing test turnaround times directly on their site. They even include a full time series and the most recent 14-day average. This is a great example of data transparency.
August 11, 2020
Our daily update is published. We have many incomplete reports from states today and two states missing at our cutoff time (AK and RI). Today’s data reflects the holiday weekend dip in testing and reporting. 47K new cases today. 518K new tests. 242 deaths (corrected from 158).

(Earlier in this thread we mentioned “3 of 4” US Census regions. There are 5 regions, counting the Pacific region, which includes Alaska and Hawaii. Apologies to our non-contiguous readers. —@kissane)
