Alabama switched its once-per-week reporting day to Wednesday. Previously, the state reported on Thursday.
Alabama did not report as expected on October 27 and November 10, 2022. This was due to upgrades to their case surveillance system. In effect, two weeks’ worth of data was published in the most recent week.
As of July 29, 2022, Alabama moved to once weekly reporting. The data is updated on Thursdays. Previously, the state was updating M-F.
On Friday, June 3, 2022, a technical issue prevented a dashboard update. This resulted in four days’ worth of data being published on June 6th and the appearance of a rapid acceleration of cases in the state.
Alabama has changed to Monday-Friday reporting
From January 13-15, 2022, Alabama did not update data due to technical issues accessing their electronic data surveillance system. The January 16, 2022 update includes data from January 13-16, 2022.
On January 1, 2022, the JHU CRC's source for Alabama was stale due to maintenance.
On October 27, 2021, Alabama reported a large number of cases, the majority of which were associated with a backlog of reporting from a large laboratory system.
In September, 2021, the JHU Coronavirus Resource Center began collecting and reporting testing data for Florida and Alabama from Health and Human Services (HHS). These states ceased reporting cumulative testing counts publicly, resulting in the need to seek an alternative source. The HHS data undergoes retrospective reporting, so historic data may change from reported data.
Alabama reported that a recent spike in the number of total tests reported was caused by backlogs the state recently processed from two large facilities over the last three to four days. The surge in cases applies to past dates, not the state’s current situation. We will provide a clearer explanation as the state provides more information.
