We await updates from Massachusetts and California, which will also have large numbers. Colorado's numbers are also climbing, standing at 28 cases as of their last update.

March 14, 2020, 1:41 PM PDT

The biggest news today is that we got a fresh total test number from MA, which had been lacking. We do not have a fresh number for Washington State, which is doing the most testing. Among smaller states, the situations in Louisiana and Colorado stand out.

March 15, 2020, 1:35 PM PDT

By known positive tests, the 10 states with the highest per capita number of cases are: Washington New York Colorado Massachusetts Louisiana Rhode Island New Jersey South Dakota New Hampshire Georgia

March 17, 2020, 11:15 PM PDT

End of day, 3/17, we have confirmed cases in all 50 states + DC and 3 territories, almost 6000 in total. WA and NY are now over 1000 cases each. Of the smaller states, Louisiana, Colorado, and Rhode Island look like hot spots.

March 21, 2020, 2:18 PM PDT

New York accelerated past Washington in per capita positive tests. Here’s the top 10:

New York Washington New Jersey Louisiana DC Michigan Massachusetts Colorado Rhode Island Illinois

March 22, 2020, 2:25 PM PDT

New York continues to have the highest positive tests per capita, an indication of both the intensity of testing there and the severity of the outbreak. Here’s the top 10:

New York Washington New Jersey Louisiana DC Michigan Illinois Vermont Colorado Rhode Island

This is just another indication that COVID-19, while it broke out on the east and west coasts, will not remain a coastal phenomenon, as Michigan, Louisiana, Illinois, Indiana, Colorado, and other states experience intense outbreaks.

@VictoriaInCO @qireau @LogicalKangaroo @samirrayani @tophtucker Thank you, Victoria.

My apologies—as some of you (and our own team) pointed out—Colorado is also reporting serology tests.

(Puerto Rico does, too.)

About antibody testing...

  1. It is necessary to separate out these tests.
  2. Antibody testing remains a small portion of the cumulative tests performed.
  3. US viral testing really has scaled up a ton.
  4. Antibody tests have grown as a % of daily tests.

Colorado, e.g.:

Colorado recently redesigned its data dashboard and no longer provides separate numbers for probable and confirmed cases. The state also didn’t update its negative test counts today.

September 1, 2020, 2:08 PM PDT

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.

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.

October 23, 2020, 4:11 PM PDT

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 26, 2020, 3:49 PM PDT

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.

November 14, 2020, 3:20 PM PST

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.)

December 1, 2020, 4:35 PM PST

A handful of states reported data for more than one day today, a result of data disruptions caused by the Thanksgiving holiday. On the other hand, CO, NJ, TX, WA, and WY only published partial updates today.

January 21, 2021, 12:49 PM PST

The CO DPHE has added variant case counts to their public dashboards. To date, most states lack the resources to add genomic surveillance to their ongoing COVID-19 workload. This data is critical to understanding the spread of SARS-CoV-2 variants in the US.
