  • 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.

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.
