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. https://t.co/qSmFF4SLva

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. https://t.co/LzKJBXTD0J

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

@NateSilver538 The other thing I’d put on your radar is an emerging southern cluster: look at the per cap numbers for LA, MS, TN. (I think those are the 3 I noticed last run.) -@alexismadrigal

March 22, 2020, 3:39 PM PDT

@1billy1 @NateSilver538 @alexismadrigal I believe it. We have been very concerned about Louisiana since the first day of the project.

March 24, 2020, 1:54 PM PDT

Across the 21 states who report them, we tracked 4,468 hospitalizations, the bulk in New York.

But Louisiana and Florida also have growing numbers of hospitalizations.

March 24, 2020, 1:59 PM PDT

Louisiana's situation is particularly worrisome. They have not done that much testing and they have high case, hospitalization, and death numbers. https://t.co/UW3kLJKS8b

March 28, 2020, 2:53 PM PDT

Louisiana remains extremely worrisome — and is just behind New York in deaths per capita. https://t.co/JMfbCnmiPy

March 30, 2020, 2:17 PM PDT

Cumulative hospitalizations up to 22,303, still largely driven by New York. California is now second in hospitalizations, Louisiana third.

April 6, 2020, 2:55 PM PDT

Some unexpected numbers came from Indiana today. Despite only having ~5000 confirmed cases, the state said today it has 924 COVID patients in the ICU and 500 on ventilators. That's not too far from California's ICU count and closing in on Pennsylvania and Louisiana's vent usage.

April 6, 2020, 5:50 PM PDT

As of today, 8 states are reporting racial demographics for COVID cases: CT, IL, MI, MN, NC, NJ, SC, VA

And 5 states are reporting racial demographics for COVID deaths: CT, IL, LA, MN, NC

April 7, 2020, 3:11 PM PDT

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.

April 8, 2020, 1:57 PM PDT

On a per capita basis, things look quite different. NY still dominates, but Louisiana—due, in part, to a large outbreak—has tested a lot of people. There are huge disparities in testing between the states, as we've often noted. https://t.co/5x75DI44E3

May 28, 2020, 2:21 PM PDT

The big numbers were driven by a few big data dumps. New York and Louisiana were way above average. But 15 states reported over 10k tests.

Unclear how much of the new variability in the numbers is due to states pulling out antibody testing and how much was just Memorial Day. https://t.co/U6a3DY6tpv

1/2 A list of states/territories in which African American COVID deaths substantially exceed the community's share of the population:

Alabama Arkansas California Colorado Connecticut D.C. Florida Georgia Illinois Indiana Kansas Kentucky Louisiana Maryland Michigan Mississippi

June 13, 2020, 2:55 PM PDT

We are seeing new hospitalization highs in Texas, Arizona, and North Carolina. We're showing Louisiana here as well for context, since it had an early COVID-19 outbreak. https://t.co/BvbW8DYEyt

June 17, 2020, 3:35 PM PDT

Among states that had an early outbreak, most are now in decent shape with lots of testing and very new cases. NY, for example, had a positive rate under 1% today.

Louisiana may be an exception. Cases are rising again and now hospitalizations have stopped falling, too. https://t.co/TSt030hhbN

June 27, 2020, 2:47 PM PDT

This is the state of things now.

(Note that OR, KS, KY LA, PA, NH, and RI did not report any new cases today.) https://t.co/hgR7FfanYk

July 3, 2020, 2:57 PM PDT

The record new cases are coming from many states. Notable jumps in Georgia, Louisiana, North Carolina, and South Carolina. (Ohio looks bad today but this number is for two days.) https://t.co/L6CJXXbuuP

July 4, 2020, 3:11 PM PDT

Our daily update is published. We see slightly lower numbers than earlier in the week, probably due to the holiday weekend. 6 states (CT, KS, KY, LA, MN, RI) did not report at all, and some others had lower numbers than usual.

Still: states reported 52k new cases. https://t.co/x830ffyPzh

July 8, 2020, 5:04 PM PDT

California set a new record for cases, but some of it was backlog from LA County. COVID-19 hospitalizations are at an all-time high, too. https://t.co/9joV9UASP0

July 10, 2020, 3:26 PM PDT

At the peak in New York on April 15, that state hit 595 cases per million.

Arizona (580) and Louisiana (568) approached that number today. https://t.co/MxvPqIC43k

July 12, 2020, 3:23 PM PDT

Florida didn't just break the record for reported cases. It also shattered the mark for cases per million population. New York, at peak, hit 595. Today, Florida reported 712 cases per million. Arkansas also entered the 500+ tier, where we've only seen FL, AZ, and LA. https://t.co/KeQmHMA9as

July 18, 2020, 3:40 PM PDT

Today, ID is back, but we’re missing hospitalization updates from states including AL, AR, CT, IA, LA, MI, MO, MS, NH, OR, RI, SC, and WY. Some due to the new HHS directive, others because it’s the weekend.

We will keep reporting on the availability of this data.

July 20, 2020, 3:11 PM PDT

Populous states can generate large case counts, but if you look at the new cases per million today, 9 smaller states are showing more cases per million than California or Texas: AL, AR, ID, KS, KY, LA, MS, NV, and SC. https://t.co/1pYW6cWRaS

July 20, 2020, 3:21 PM PDT

Louisiana has posted record case counts back-to-back after not reporting on Saturday.

One positive thread: compare the hospitalizations to cases charts and it's clear we're diagnosing more infections.

On 4/2, LA's first peak, they did 5,300 tests. Today, 33,620. https://t.co/rgmowepkFE

July 26, 2020, 3:05 PM PDT

Here's your look at the number of new cases per million. Louisiana has stopped reporting on Saturdays, so that's two days worth of cases. https://t.co/Zd7AfHLulO

August 2, 2020, 3:50 PM PDT

Something to watch out for: Some states have stopped reporting on both weekend days. For example, Louisiana didn't report yesterday, so today's numbers for the state are inflated. https://t.co/KZ78GZFNe7

October 17, 2020, 3:14 PM PDT

Wisconsin and four other states—Connecticut, Louisiana, Kansas, Rhode Island—did not update their case numbers today.

Today's case count was high, despite the absence of these states. https://t.co/7Bh16lsBko

October 22, 2020, 4:26 PM PDT

We’re still compiling data on COVID-19’s spread through long-term care facilities. Complicating the effort recently: Florida went nearly three weeks without releasing long-term care death data, and Louisiana’s cumulative counts appeared to drop with facilities marked as “closed.”

November 26, 2020, 4:01 PM PST

The following jurisdictions did not report today: AS, CT, FL, KS, KY, LA, MA, MI, MN, MP, NC, NH, OH, RI, SC, SD, UT, VI, VT, WY. 10 more reported partial data. Some will report two days of data tomorrow.

December 17, 2020, 3:15 PM PST

As hospitalizations continue to rise nationwide, many states that experienced significant outbreaks in earlier months are again under strain. 12 states have surpassed 300 currently hospitalized per million people in 2 distinct periods. Louisiana has been above that level 3 times. https://t.co/PXHEt9rQx5

December 25, 2020, 4:15 PM PST

20 states provided no update: AK, CA, CT, DC, ID, KS, KY, LA, MA, MI, MN, MP, NC, ND, NH, OH, RI, SC, SD, UT, VT.

7 other states made partial updates.

December 30, 2020, 4:44 PM PST

Louisiana reported a record 6,754 COVID-19 cases today. The state department of health notes that this does not include a backlog of cases or multiple days of reporting.

January 30, 2021, 4:23 PM PST

Today’s update includes no data from CT, KS, LA, or RI, and no data except hospitalizations from AL. The MA update includes data from approximately 24,800 PCR tests not reported yesterday due to a technical problem.

February 27, 2021, 4:12 PM PST

A reminder that some states do not report COVID-19 data on the weekends, and today's figures are missing updates from: AK, CT, KS, LA, MP, NM, RI, and WY. https://t.co/5XpgjRdDH0
