More than 9,529 cases of coronavirus have been confirmed in the UK, but the actual number of cases is estimated to be much higher.
The number of deaths is 422, according to figures from midday on Tuesday. Public Health England said updated figures for Wednesday had been delayed.
More than 82,300 people in the UK have been tested for the respiratory infection but were found not to have it.

The following charts and graphics will help you understand the situation in the UK and how the authorities are dealing with it.
1. The UK has increased measures to combat the virus
The new coronavirus, which causes the respiratory disease known as Covid-19, was first confirmed in the UK at the end of January.
While there were a number of people testing positive throughout February, figures in the UK began to increase at the beginning of March.
Most of the cases in the UK are in England, primarily in London. England has at least 7,973 confirmed cases. Scotland has 719, Wales 628 and Northern Ireland has 209, according to Public Health England’s latest figures.
In a bid to slow the virus’s spread, Prime Minister Boris Johnson has urged everyone to stay at home. He said police would be given powers to fine people deliberately flouting the new restrictions, which would last for an initial period of three weeks.
Most shops, apart from those selling food and medicines, have now closed. Schools have shut their doors, except for vulnerable pupils or children of key workers. Cafes, bars, leisure centres and other social venues have also been told to shut.
The government had earlier asked people to work from home where possible and halt all unnecessary travel.
Those aged over 70 have also been asked to self isolate at home over the coming weeks and letters are being sent to 1.5 million people in England who are most at risk of coronavirus, urging them to stay at home.
UK figures are currently lower than some other European countries, such as Italy, for example, where there have been more than 74,000 cases and more than 7,500 deaths, according to 25 March figures from the Johns Hopkins University.
Globally, authorities have confirmed more than 450,000 cases of the coronavirus and almost 20,500 deaths.
2. London has seen the most deaths
The capital has experienced the highest number of deaths, with figures reaching more than 150 by Tuesday.
London Mayor Sadiq Khan has urged workers to stay at home and said public transport should only be used by key workers, otherwise “people will die”.
3. We are in the second phase of the government’s response
The government’s action plan for dealing with the virus involves three phases – contain; delay; mitigate – alongside ongoing research.
After trying to contain the disease, the country moved to the “delay” phase on 12 March to stop the wider spread of the virus.
The government announced tougher restrictions on peoples’ movements.
Even if you have no symptoms, the government says you should:
- Stay at home – only go out for essential shopping or medicines and to exercise once a day
- Stop all non-essential contact with others – public gatherings or more than two people are banned
- Stop all unnecessary travel – you can travel to work if absolutely necessary
- Work at home where possible
The government is now encouraging self-isolation at home for over 70s, and those more vulnerable to the virus, for 12 weeks.
British nationals should avoid all non-essential foreign travel to tackle the spread of coronavirus, the Foreign Office has advised.
Retired NHS staff have been asked to return to work. A government appeal for 250,000 volunteers to help deliver foods and medicines for the vulnerable prompted more than 405,000 responses in 24 hours. Mr Johnson said they would play a crucial role in helping fight the virus.
4. People who think they have coronavirus should self-isolate
Symptoms include a high temperature and a “new, continuous” cough – this means coughing a lot for more than an hour, or three or more coughing episodes in 24 hours (if you usually have a cough, it may be worse than usual).
If you think you have coronavirus you are advised not to go to a GP surgery, pharmacy or hospital. Instead, you stay at home for seven days. If you live with other people, you should keep at least 2m away from them and they should also stay home for 14 days to see if they develop symptoms.
If your symptoms persist or worsen you should contact the NHS’s dedicated 111 online coronavirus service or call 111.
