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.
UKHSA collects these notifications and publishes analyses of local and national trends every week.
On Tuesday 7 June 2022, monkeypox was made a notifiable disease. This means that the above duties apply in terms of notification of suspected and laboratory confirmed cases. The publication on 13 June, covering week 23, is the first week that these cases will be reported as a notifiable disease within this publication.
The figures for both suspected cases and laboratory confirmed cases might vary compared to other official sources for a number of reasons, such as:
differences in timings of when the data is compiled
duplicate data if individuals have been tested more than once, as this report is based on anonymised notifications
different timelines for reporting suspected cases and laboratory confirmed cases
confirmed cases may not have been reported as suspected cases
