Third case of monkeypox diagnosed in the UK

Public Health England (PHE) has confirmed that three patients have been diagnosed with monkeypox in England. The first two patients are believed to have acquired the infection in Nigeria before travelling to the UK, while the third patient is a healthcare worker involved in the care of the second patient before monkeypox was diagnosed.

The first patient is a resident of Nigeria, and has received treatment at the Royal Free Hospital in London under strict isolation procedures. Prior to this, the patient was staying at a naval base in Cornwall. The second patient had travelled to Nigeria, and first presented to Blackpool Victoria Hospital, before being transferred to Royal Liverpool University Hospital for specialist care. The third patient is now isolated and is being looked after in a specialist unit at Royal Victoria Infirmary, Newcastle.

PHE said it would be contacting people who may have been in close contact with the individuals to provide information and health advice. The cases are the first ever diagnoses of monkeypox in the UK.

PHE has stressed that the infection does not spread easily between people and that the risk of transmission to the wider public is very low. However, it has produced guidance on diagnosis and treatment of the condition and commented that following a large sustained outbreak in Nigeria in 2017, monkeypox could continue to affect travellers returning from this area.
