The U.S. Centers for Disease Control and Prevention (CDC) announced that it will publish COVID-19 cases and deaths on a weekly basis, marking a major shift in its reporting since the start of the pandemic.

“To allow for additional reporting flexibility, reduce the reporting burden on states and jurisdictions, and maximize surveillance resources, CDC is moving to a weekly reporting cadence,” the federal agency said in a statement last week.

Beginning on October 20, 2022, CDC will report updates to COVID-19 aggregate case and death data and line level data on a weekly, rather than daily, cadence. Data processing cutoffs for jurisdictions will be every Wednesday at 10AM ET for line level case and death data, and Wednesday at 5PM ET for aggregate case and death data.
