Because Minnesota’s data is “current as of 4 p.m. the previous day”, this change in their reporting schedule results in the data reported for November 27, 2020 being the data that would normally have been reported on November 26, 2020.

On 10/14, MN's Probable Deaths decreased from 53 to 6, resulting in a decrease in Total Deaths from 2197 to 2180.

October 8, 2020

Variables affected:

On 10/8, MN released a new source for Currently Hospitalized and Currently in ICU. For Currently Hospitalized, we captured this data point as non-ICU + ICU.

October 5, 2020

Variables affected:

On 10/5, MN released current hosp/ICU values in their PR after we'd deleted them for being 7 days old two days prior. As of 10/5, curr. hosp. was 367, and curr. ICU was 123. MN PRs update on MWF, so we will look more closely for those values on those days.

Variables affected:

On July 30th, MN started re-reporting total tests by unique people. We are starting to track this figure starting on July 30th going forward. This will impact the total test metric that is on our website by 200,000 tests as well as negatives.

March 6, 2020 to June 13, 2020

Variables affected:

In a previous backfill that took place on 6/14, we updated Minnesota's Positives column using state-provided historical data. Minnesota's positives are confirmed cases, so when we did so, we should have also updated the Positive Cases (PCR) column to match what we put in Positives. This has now been done for 6/13 and earlier (the data after that is fine because the Data Entry pub shifts have been setting both correctly since the backfill).

On April 26, 2020, while attempting to fix a data entry error for Minnesota on April 25, 2020, we mistakenly put the corrected value for that day in April 24, 2020. This made Negative PCR Tests (people) and Total Test Results incorrect for both days. Both days now have the correct values.

Tags: CTP Backfill Mistake Correction

Minnesota's negative test results for April 24, 2020 were incorrectly entered, causing both Negative PCR Tests (people) and Total Test Results to be incorrect. This error has been corrected.
