Some 53 people have now died after testing positive for Covid-19 in the UK, the government has said.
It comes after prime minister Boris Johnson urged the country to end all non-essential contact, work from home and avoid pubs, clubs and theatres.
Making a statement in the Commons on the coronavirus outbreak, Health Secretary Matt Hancock said the pandemic is “the most serious public health emergency that our nation has faced for a generation”.
Hancock said: “Our goal is to protect life. Our actions have meant that the spread of the virus has been slowed in the UK and I want to pay tribute to the officials at Public Health England and the NHS for their exemplary approach to contact tracing and their work so far.
“However, the disease is now accelerating and 53 have sadly now died. Our hearts across this whole House go out to their families.”
