Our Data

Negatives = (Totals - Positives) Positives occasionally update before totals do; do not revise negatives down, keep the last calculated negative. Last Updated (Local Time) = (current date + time = 00:00)

Total tests are taken from the annotations on the charts on the page. Negatives = (Totals – Positives) Positives occasionally update before totals do; do not revise negatives down, keep the last calculated negative. Last Updated (Local Time) = (today's date + time = 00:00)

Our data comes from a press release from 5/1

Dashboard now has a new tab that details total tested. Negative = Total - Positive. We do not currently track it, but hospitalization and ICU data is available from Maricopa County and Pima County.

California has been inconsistent in its timing of reporting. We used faster-updating sources until 4/1, when we standardized on its new data dashboards. This led to a drop in cases and deaths, as the state's data lags county sources. The state reported a huge batch of negative tests on April 4 and again on April 22. As of April 22, California now reports specimens tested instead of people tested. Because some people may be tested more than once, this number is probably higher than the number of people tested.

Negative = People Tested - Cases. Cases include people who test positive for COVID-19 AND people who have symptoms of COVID-19 and are a close contact to someone who tested positive. As of April 27, Colorado is reporting people tested.

Negative = Total - Positive.

On March 21, negatives jumped due to a methodology change: tests of people not investigated as PUIs are now included. As of April 27, Florida reports specimens tested because some people may be tested more than once, this number may be higher than the number of people tested.

Positive includes deaths. Positives occasionally update before totals. We use the state's "as of" time as our Update Time. As of April 27, Georgia is reporting people tested.

On May 4, Guam adjusted cases down from 150 to 149 because they found that the case was double counted, number of recovered was also adjusted down because 7 people were returned to isolation. Guam's counts include 11 people tested at the San Diego naval base.

Michigan has reported each day's negative results since 3/10 but has never totaled them. We sum all the negative results and report the total. Michigan reports specimens tested instead of people tested. Recovered counts are updated once a week. On 4/26 we mistakenly entered the total number of tests in place of the total number of negative results: we are fixing this issue.

Since 3/23, Negative = Total - Positive.

Negatives = Total - Positives. Hospitalizations are calculated by calculating multiplying % of hospitalized times total cases, pending clarification from the state. Recoveries are estimated, and updated twice weekly. As of April 27, Mississippi is reporting people tested.

Negative = Total - Positive. The dashboard says that the data "as-of" is from the day previous - in this case we use current date + time = 0:00

The count of 56 on 4/27 included a death erroneously entered into NE’s electronic system. NE removed it from the total count on 4/28 We do not currently track it, but partial hospitalization data are available from Douglas County

Individual data fields have different update times; we use the latest as our "Last Update" time. Hospitalizations, ICU bed usage, and ventilator usage are reported as a percentage of total capacity in daily situation reports, but total capacity is not published, so we do not estimate those numbers. As of May 6, Nevada is reporting both specimens and people tested. We report positives and negatives based on the number of people tested.

On May 4, NH revised the recovered down from 1107 to 1017. Negative count is from the four largest labs. Pending count is from the Public Health Laboratories only. As of April 27, New Hampshire is reporting people tested.

As of April 27, New Mexico is reporting people tested.

Numbers come from press conference. Recovered = discharged. As of April 27, New York is reporting people tested. Cumulative hospitalized and recovered are calculated using the 3 day average change in hospitalization benchmarked from April 12.

Negative = Total tests* - total positives (where total tests include all data from public labs and partial data from hospital and commercial labs).

As of May 2, North Dakota is reporting people tested.

Ohio now publishes detailed Key Metrics

Executive Order Reports first reported comprehensive test results on 4/6. We exclude "Positive (Out-of-State)" results, as we assume these are isolated outside the state. As of April 27, Oklahoma is reporting specimens tested. Because some people may be tested more than once, this number is probably higher than the number of people tested.
