It comes after 13 new patients were diagnosed on Sunday.

The latest cases included 12 more in England and the first patient in Scotland, meaning the virus has now reached all four parts of the UK.

A health worker at an NHS cancer centre in Middlesex is also among the new cases.

Another is a staff member at Wimbledon College in south-west London, which has closed for deep cleaning.

Three of the new cases in England were linked to a man from Surrey, who was the first patient to not have been abroad recently and was instead infected within the UK.
