Weekly NOIDS reports have been resumed

In 2024 the UK Health Security Agency (UKHSA) rolled out a new case and incident management system to support the function and capabilities of our health protection teams. UKHSA paused publication of notifiable diseases weekly reports after week 26 2024 while data checks were carried out. These checks were completed and the NOIDs weekly report was reinstated in October 2024.

Due to changes in the way the data is now processed and mapped (including local authority codes that have been updated to the latest geographies) it would be inaccurate to compare data since week 27 2024 to historic reports.

Further refinements to the way the data is displayed and processed will be carried out over time and its overall quality improved. Public health action is taken on notifications as we receive them and is not impacted by the change in system.

Causative agent reporting has been unaffected.

Transition to the new case and incident management system was effective from a different date in each region of England, spanning weeks 27 to 39 of 2024. The transition dates are included below and affect the comparability of the statistics either side of these points:

  • South East - 2 July 2024 – week 27
  • South West - 9 July 2024 – week 28
  • East of England - 11 July 2024 – week 28
  • Yorkshire and Humber - 16 July 2024 – week 29
  • North East - 18 July 2024 – week 29
  • West Midlands - 23 July 2024 – week 30
  • London - 30 July 2024 – week 31
  • East Midlands - 17 September 2024 – week 38
  • North West - 24 September 2024 – week 39

Registered medical practitioners in England and Wales have a statutory duty to notify a proper officer of the local authority, often the consultant in communicable disease control (CCDC), of suspected cases of certain infectious diseases.

These weekly reports analyse the number of suspected cases of notifiable illnesses in England and Wales in 2024.

All weekly data is provisional.

Older weekly NOIDs reports are also available:
