Mpox

Last updated on Thursday, 16 April 2026 at 11:12am

Mpox is an infectious disease caused by the MPXV virus. Historically, mpox was known to occasionally pass on from infected animals to humans, with humans sometimes passing it on to other people that they had close contact with. Since May 2022, cases of human mpox have been reported in multiple countries that have not previously had MPXV detected in animal or human populations.

This page provides updates about mpox clade Ib and clade IIb cases in the UK. More detailed information is published monthly in the mpox outbreak epidemiological overview.

This page is updated once a month. The next update will be on Thursday 7 May at 09:30am.
