What is monkeypox and what are the symptoms as second case is diagnosed in Britain?Â

The patient, who had travelled to Nigeria where they are believed to have acquired the infection, presented with symptoms at the Blackpool Victoria Hospital, Public Health England (PHE) said.

It is the second ever case of the rare viral infection recorded in the UK, after a resident of Nigeria staying at a naval base in Cornwall was diagnosed last week.

However there is '˜no UK link' between the two patients, PHE said.
