Correction to COVID-19 case rates data

Between 10 April and 27 April, published rolling-average case rates for COVID-19 were incorrect due to an error in population estimates used to calculate these metrics. As of 4pm on 28 April, these have been corrected. More information.

What's new

Last updated on Thursday, 13 February 2025 at 08:35pm

We regularly update the dashboard with new data and features. Here we'll show a timeline of changes that have happened outside of the weekly data refresh.

    • You can now use the mouse to hover over the trend lines of a chart to see precise data points. This new feature applies to all the charts displayed on the dashboard. It allows you to instantly see the data at any point on the chart.

    • We have added data for E. coli resistance to ciprofloxacin, co-amoxiclav, gentamicin and piperacillin with tazobactam.

    • Around 500 COVID-19 cases which were reported between May and December 2024 were added into UKHSA’s case recording system in the week beginning 30 December 2024, and were published on the UKHSA data dashboard on 9 January 2025. These cases were not added at the time of initial reporting because of a technical issue affecting a small number of COVID-19 case reports. Following further investigation and the publication of additional cases on the UKHSA data dashboard on 30 January 2025, the total number of retrospective cases added is now around 600.

      The retrospective addition of COVID-19 cases into UKHSA's case recording system was caused by the failure of an automated data transfer process following a network outage within one of the UKHSA Data Centres. This process was already scheduled to be addressed as part of a wider project on processing of laboratory results. As a result of this incident all data transfers of this kind will now have additional monitoring in place until they are replaced through the ongoing work.

      No further cases are expected to be added as a result of this incident. Overall COVID-19 trends and COVID-19 positivity are unaffected.

    • We will pause updates for the dashboard over Christmas and resume the first week of January. This means we will add new data from 2 January.

      Here are the days we expect to publish in January. Data for Influenza, RSV and other respiratory viruses will update on 3 January, when the report containing the data is published.

      • COVID-19 Testing data: 2 Jan
      • COVID-19 Cases data: 2 Jan
      • COVID-19 Vaccinations data: 2 Jan
      • RSV data: 3 Jan
      • Influenza data: 3 Jan
      • Other respiratory viruses data: 3 Jan
      • COVID-19 Deaths data: 9 January
      • COVID-19 Hospitalisations data: 9 Jan
      • Healthcare-associated infections data: 9 Jan
      • Measles data: 16 Jan
      • Cold Health Alerts won't be paused
    • We have updated how Weather Health Alerts are displayed on the dashboard.

      On the homepage all regions are now grouped according to their alert status. Each alert status and colour is now clearly labelled.

      On the full screen map, we have added a key to the bottom left-hand corner of the map. This explains the alert status for each colour used (green for 'No Alert', yellow for 'Yellow Alert', amber for 'Amber Alert' and red for 'Red Alert'). You can show and hide the key on the map. We have also added UKHSA's logo in the top right-hand corner.

    • On 11 November 2024, a data processing error led to a pipeline failure and prevented the COVID-19 positivity dataset from being produced.

      Following this failure, work has been undertaken to understand the root cause and reinstate the pipeline. We have also completed an investigation to ensure the accuracy and reliability of data published. Additional resilience has been added to the data processing.

      Publication of COVID-19 positivity is expected to resume on Thursday 5 December 2024.

      Positivity from a different source is published in the National Flu and COVID-19 Surveillance Report (Figure 6a).

    • We've added data for the latest COVID-19 vaccine booster campaign to the dashboard. Overall uptake can be found on the homepage and more detailed breakdowns can be found on the COVID-19 topic page.

    • Entry category: Change to metric
      Entry title: Measles data now updated monthly

      The severity of the measles outbreak has been downgraded. As a result, we will report measles data monthly rather than every 2 weeks.

      The next update will take place on Thursday 21 November.

    • We have made several changes to the UKHSA homepage to update its design and make it more user friendly.

      The homepage's layout is now grouped according to theme. You can now instantly see data for any outbreaks and respiratory viruses. We have updated the summary cards for each health topic to make the information clearer and easier to understand.

      The homepage now features a summary card for weather health alerts. This includes a map of England showing all the alerts currently in place across the country.

      In keeping with the latest design changes to GOV.UK, the homepage now includes a blue 'hero' banner at the top. The dashboard now stretches to the full width of your screen.

      We are keen to know what you think of the new changes. Please let us know using our feedback form.

    • We have updated the way we present regional level influenza hospital admission rates. We have combined the 9 UKHSA Regions into 4 UKHSA Super Regions for:

      • North of England
      • South of England
      • Midlands and East of England
      • London

      Any data reported from 30 September will use these new larger regions. You will be able to filter data for previous seasons by either the 9 UKHSA Regions or the 4 UKHSA Super Regions.

      Influenza hospital admissions rates are based on a subset of trusts who voluntarily report. Participating trusts are distributed across England, but due to the voluntary nature of participation, some regions may have lower levels of trust participation. We have made this change to aid interpretation.
