  • On September 12, 2022, Texas switched to providing data Monday, Wednesday, and Friday. Previously, the state was providing data M-F (since August 1). The Coronavirus Resource Center's reporting for Texas" cases and deaths takes a composite approach where some locations are sourced from county health departments. These counties may update on a different schedule. While some data will likely be published most days, the bulk of the data will be released on Mondays, Wednesdays, and Fridays with the state update.

  • On January 14, 2022, the US state of Texas published a cleaned dataset aligning their published case data with their final COVID-19 data of 2020 that they provided to CDC. The JHU CRC has recreated the Texas county-level time series files to match those published by the Texas Department of Health Service. Doing so allows us to remove the artificial state level spike and the volatility in the county-level data. We have received confirmation from the state their confirmed time series and probable time series are organized by date of report so they are suitable for our repository.

    Within the 2020 file of the Texas state time series files, there were included 47,583 confirmed cases and 5,707 probable cases with an "unknown date" entry. As recommended by the state, we have assigned these cases to December 31, 2020.
