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
The Recovered data point we report for New Jersey reflects the number of COVID-19 patients discharged from the hospital and therefore does not represent the total number of people who have recovered from COVID-19, since many people with COVID are never hospitalized.
Negative test results reported in our API and CSVs are calculated by subtracting Positive PCR tests (people) from Total PCR tests (specimens).
On October 23, New Jersey's reported Ever hospitalized value increased dramatically from 24,517 to 37,222 with no explanation we could find: this was probably a one-time addition of backlogged data.
On September 1, New Jersey did not update their total PCR test figure by the time of our update, however total cases increased from 191,160 to 192,290.
On August 7, 2020, we back-filled New Jersey's Probable deaths with data provided by the state. This removed apparent spikes in deaths due to the state's irregulat reporting.
On August 4, 2020, New Jersey's Now hospitalized* number decreased by 268 people.
On July 19, 2020, New Jersey's Total cases decreased, perhaps due to reclassification of probable cases.
On July 16, 2020, New Jersey's Recovered figure decreased.
On May 16, 2020, a backfill effort by New Jersey caused the state's data for Recovered to rise by approximately 7,000 people.

38 states reported over 1k cases. CO, IN, KY, MD, MN, MO, MT, ND, NH, NJ, NV, PA, WV, and UT all set records for detected cases. (5 states did not report cases.)

We were able to backfill all New Jersey deaths, redistributing the previous large June 25 spike of probable deaths to the correct days. Thank you to @govmurphy and @NJDeptofHealth for publishing the data we needed to improve the dataset.
August 7, 2020
Data on current hospitalizations remains iffy. Today we saw hospitalization numbers in ID and NJ drop by ~50%, which seems unlikely to reflect reality. Some states with rising cases have dropping hosp. figures. Last week's post is likely still relevant:
