Correction to COVID-19 case rates data

Last updated on Monday, 28 April 2025 at 04:02pm

Entry category: Data issue
Entry description:

As the result of a systematic error in reference data containing population estimates, 7-day rolling-average COVID-19 case rates were incorrectly calculated. The error appeared on 10 April and was resolved on 28 April, with the corrected metrics released at 4pm.

During this period, all case rates appeared as half their expected value. This affected users interacting with the Case rates by specimen date (7-day rolling average) and Case rates by specimen date and sex (7-day rolling average) charts, downloading the corresponding data or accessing these metrics using our API or by other automated means.

Overall trends in COVID-19 case rates remain unaffected. Other COVID-19 metrics including case numbers, testing numbers, positivity, hospital admissions and deaths also remain unaffected.

We have taken steps to improve our data quality processes to help prevent similar issues occurring in the future.
