Yes, but the process varies depending on whether jurisdictions’ historical data includes dates. If the historical data include dates, CDC incorporates it into the jurisdiction’s cumulative data as soon as possible. If the historical data do not include dates, CDC incorporates it into the cumulative counts. This new data would be omitted from other metrics until the jurisdiction provides dates. CDC requests that jurisdictions report date information. Here’s how those scenarios are handled when specific dates cannot be provided for historical data: If a jurisdiction provides a date range, CDC equally distributes these data across that date range. If no date range is provided, CDC equally distributes the data across the first date the jurisdiction began submitting data to CDC through the date the new data were first received.
