Overview
- UKHSA confirmed a single travel-associated mpox case in England, with the patient in isolation, contacts under follow-up and no secondary cases reported so far.
- Sequencing showed a recombinant virus with elements of clades Ib and IIb, a pattern the agency says can occur where multiple lineages co-circulate.
- Reports differ on the patient’s recent travel destination, but officials describe the case as imported while investigations continue.
- UKHSA has shared findings with the WHO and partners to bolster global surveillance and coordinate assessment of any public-health implications.
- Labs are evaluating protection from the MVA‑BN vaccine as studies estimate 75–80% effectiveness overall, while Mexico reports ongoing clade II circulation without Ib detections.
