Data Reporting Assessment (Learn more about data quality assessments)

Last updated

When Mississippi reports no data, several days of data, or unusual data (such as decreases in values that should increase), our volunteers note it here on the date the anomaly occurred. We also note here changes in our own methodology that affect the data.

Mississippi started updating testing totals on a weekly schedule on September, 27, 2020, so each update includes many days worth of testing.

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

From May 21, 2020 through May 26, 2020, we briefly captured Mississippi's Positive antibody tests (specimens) through state press conferences. As of May 26, 2020, Mississippi no longer reports this metric. On February 11, 2021, we cleared Mississippi's Positive antibody tests (specimens) timeseries to ensure that our data is as accurate and consistent as possible.

On October 25, 2020, Mississippi announced that COVID-19 data for October 24, 2020 and October 25, 2020 would be published on Monday. As a result, Mississippi did not update on October 24, 2020 and October 25, 2020.

On September 15, 2020, Mississippi resumed reporting current hospitalizations, ICU, and ventilations on the source we have historically used for this metric. We are working to backfill these data points in our historical data.

On September 11, 2020, we discovered a new source for Mississippi current hospitalizations and current ICU admissions on the Mississippi State Department of Health website.

Between June 17 and June 22, 2020, Mississippi experienced technical difficulties with their reporting system. We filled in five days of case and death data on June 22, 2020.

On May 26, 2020, news reports indicated that 95 antibody tests had returned positive in Mississippi, but we have not found more recent data since then for this metric.

As of May 23, 2020, Mississippi is separating out PCR and antibody tests. We now report both separately.
