Mpox clade Ib and mpox clade IIb reporting now monthly
Last updated on Thursday, 16 October 2025 at 11:36am
From Thursday 16 October the frequency of updates to mpox clade Ib and mpox clade IIb data will reduce from weekly to monthly to match the epidemiological overview published on GOV.UK. This change reflects the current situation where case numbers remain low and stable.
The national response to the mpox outbreak is now being scaled back as there is no longer a need for an active outbreak response. Routine public health surveillance will continue to monitor any new cases and provide updates when needed. If the situation changes the UKHSA will review the reporting frequency and provide updates as required.
