Weekly NOIDS reporting pause

The weekly UKHSA NOIDs publication is currently paused (from 3 April 2025) to make changes, including adding the notifiable diseases which became reportable under the Health Protection (Notification) (Amendment) Regulations from 6 April 2025.

Public health action will continue to be taken on notifications as usual. It will not be impacted by the reporting development work.

For reports already published, please be aware that due to changes in how the data is 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 to historic reports.

The causative agent reports will continue to be published.

Registered medical practitioners in England and Wales have a statutory duty to notify their local authority or local health protection team of suspected cases of certain infectious diseases.

All laboratories in England performing a primary diagnostic role must notify UKHSA when they confirm a notifiable organism.

Scarlet fever and group A streptococcus

Cases of scarlet fever are taking longer to appear in our published data after initial processing and review. Our teams are working at pace to ensure published data reflects all formal notifications received and local authority data will be updated once full data entry has occurred. In the meantime, our real-time GP Syndromic Surveillance data reflects current trends.

UKHSA teams continue to manage outbreaks of scarlet fever, irrespective of whether it has been entered into NOIDs, and have carried out all necessary public health interventions needed to reduce further transmission in outbreaks, especially in vulnerable settings such as schools and nurseries.

For scarlet fever notifications that are published, it is inaccurate to compare data since week 27 to historic reports due to a change in the way that notifications are processed.
