In a update on the monkeypox situation in England, the UK Health Security Agency (UKHSA) has detected 4 additional cases of monkeypox, 3 in London and one linked case in the north east of England.
Investigations are underway to establish links between the latest 4 cases, who all appear to have been infected in London. All 4 of these cases self-identify as gay, bisexual or other men who have sex with men (MSM).
Currently, common contacts have been identified for 2 of the 4 latest cases.
There is no link to travel to a country where monkeypox is endemic, and exactly where and how they acquired their infections remains under urgent investigation, including whether they have further links to each other.
Those patients needing medical care are all in specialist infectious disease units at the Royal Free Hospital, Royal Victoria Infirmary in Newcastle upon Tyne and Guys’ and St Thomas’. The individuals have the West African clade of the virus, which is mild compared to the Central African clade.
These latest cases mean that there are currently 7 confirmed monkeypox cases in the UK, diagnosed between 6 and 15 May.
Due to the recent increase in cases and uncertainties around where some of these individuals acquired their infection, we are working closely with NHS partners to identify if there may have been more cases in recent weeks, as well as international partners to understand if similar rises have been seen in other countries.
