Data as of November 19 2020

Notes:

The Recovered data point we report for Colorado 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.

On November 18, 2020, we shifted the entire time series of Colorado metrics by one day to match the date that the state reports on its dashboard.

On November 13, 2020, the state of Colorado reported an increase in Positive PCR tests (people) that is less than that of the increase in Positive PCR Tests (people). This resulted in a large decrease in Negative (People or Cases) metric due to our calculations. For now we are holding this metric, Negative PCR Tests (People), constant until further notice

Negative test results reported in our API and CSVs are calculated by subtracting Positive PCR tests (people) from Total PCR tests (specimens) in the absence of better data.

As of August 13, 2020, Colorado's total test results reflect total test encounters. The number of unique people tested is available in our API as totalTestsPeopleViral.

On July 27, 2020, Colorado posted a notice that, "Due to a server issue yesterday and today with our electronic laboratory reporting system, the number of tests completed and cases reported today, July 27, 2020, may be artificially low." We report Colorado data a day after posting due to timing, so this note applies to the data published on July 28.

On June 14, 2020, Colorado revised previous "daily discharged" numbers. This caused an overall decline in their Recovered data.

On May 15, Colorado started reporting deaths for which COVID-19 is listed on the death certificate, in addition to the figure it already provided, deaths among laboratory-confirmed and probable cases (whether or not COVID was a cause of death). On July 1, 2020, we revised our historical data to reflect the death-certificate metric instead of the deaths-among-cases metric. Because of this change in methodology, there is a drop from 1,091 deaths on May 15 to 878 on May 16 in our data. Colorado also reports subsets of confirmed and probable COVID-19 deaths, but these metrics correspond to the deaths-among-cases metric we no longer report, so we do not compile this data.

Our latest tweets about Colorado

Our twitter handle is @COVID19Tracking@COVID19Tracking

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.)

November 14, 2020

A reporting error in CO resulted in an additional 16,000 test encounters and 1,540 positive cases. Also KS corrected a typo in their current ICU totals causing the figure to increase from 2 to 103.

October 26, 2020

AL, CO, OR, UT, SD, and RI all reported record high case counts. Both ND and SD are reporting more than 1,000 cases per million people.

October 23, 2020

Where possible, we now use states’ “Test Encounters” or “Specimens” as the unit for these total tests, rather than “Unique People.” (This is all fairly complicated, there’s tons of detail in the blog post.) So far, we’ve switched CO, MA, ND, and RI w/ many more on deck.

September 17, 2020

Shout out to Colorado, where the health department has clearly placed emphasis on reporting a full, granular dataset on COVID-19 outbreaks. Colorado's long-term care reporting should be a model for other states.
