When Florida shifting their reporting to once per week in June, their reports no longer included county-level deaths. The JHU CRC has reintroduced county-level death data by leveraging the HHS Community Profile Reports: https://protect-public.hhs.gov/datasets/HHSGOV::community-profile-report-counties/about

The data for October 1, 2021, includes multiple days of reporting from Florida. Florida only reports COVID-19 data once per week via their COVID-19 Weekly Situation Report, and does not provide a daily back-distribution of Case or Death data. The CDC also supplies some daily reporting for Florida. While not all of Florida's Cases/Deaths were diagnosed/occurred on October 1, we are unable to break them out to dates within the week. This contributes to the unusually large number of daily cases for October 1 in the US.

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.

The data for September 24, 2021, includes multiple days of reporting from Florida. Florida only reports COVID-19 data once per week via their COVID-19 Weekly Situation Report, and does not provide a daily back-distribution of Case or Death data. The CDC also supplies some daily reporting for Florida. While not all of Florida's Cases/Deaths were diagnosed/occurred on September 17, we are unable to break them out to dates within the week. This contributes to the unusually large number of daily cases for September 17 in the US.

The data for September 17, 2021, includes multiple days of reporting from Florida. Florida only reports COVID-19 data once per week via their COVID-19 Weekly Situation Report, and does not provide a daily back-distribution of Case or Death data. The CDC also supplies some daily reporting for Florida. While not all of Florida's Cases/Deaths were diagnosed/occurred on September 17, we are unable to break them out to dates within the week. This contributes to the unusually large number of daily cases for September 17 in the US.

On Sept. 13, 2021, the Johns Hopkins Coronavirus Resource Center (CRC) began to use data from the Centers for Disease Control and Prevention (CDC) for cases and deaths in Florida and Iowa. The CRC prefers to collect data directly from states and counties. But Florida and Iowa only report state data once per week, a cadence that has continually caused spikes and declines in cases and deaths in both states as well as in overall U.S. information. The CRC has elected to use the more-frequently updated state-level data collected by the CDC for Florida and Iowa and back-distribute it to the appropriate dates each week when the states’ reports are released. The data is back-distributed through August 10, 2021, and we are investigating if it is possible to go back further.

The data for September 10, 2021, includes the past week's worth of data from Florida. Florida only reports COVID-19 data once per week via their COVID-19 Weekly Situation Report, and does not provide a daily back-distribution of Case or Death data. While not all of Florida's Cases/Deaths were diagnosed/occurred on September 10, we are unable to break them out to dates within the week. This contributes to the unusually large number of daily cases for September 10 in the US.

The data for September 3, 2021, includes the past week's worth of data from Florida. Florida only reports COVID-19 data once per week via their COVID-19 Weekly Situation Report, and does not provide a daily back-distribution of Case or Death data. While not all of Florida's Cases/Deaths were diagnosed/occurred on September 3, we are unable to break them out to dates within the week. This contributes to the unusually large number of daily cases for September 3 in the US.

The data for August 27, 2021, includes the past week's worth of data from Florida. Florida only reports COVID-19 data once per week via their COVID-19 Weekly Situation Report, and does not provide a daily back-distribution of Case or Death data. While not all of Florida's Cases/Deaths were diagnosed/occurred on August 26, we are unable to break them out to dates within the week. This contributes to the unusually large number of daily cases for August 26 in the US.
