Wales has recorded 89 new cases of coronavirus in its biggest day-on-day increase yet, taking the UK's total to more than 4,000.
The total number of confirmed cases in Wales now stands at 280, but its true total is likely much higher.
The latest rise came a day after pubs, restaurants, gyms, theatres and other businesses were told to close as the Covid-19 shutdown was ramped up.
Dr Chris Williams, incident director for the novel coronavirus outbreak response at Public Health Wales, said: "Eighty-nine new cases have tested positive for novel coronavirus in Wales, bringing the total number of confirmed cases to 280, although the true number of cases is likely to be higher.
"Novel coronavirus is now circulating in every part of Wales.

"Three people in Wales who tested positive for novel coronavirus have now died.
"We are working closely with health boards, NHS 111 and the Welsh Government to develop systems so that NHS Wales and members of the public have appropriate access to testing.
"Based on careful risk assessment, a phased rollout of testing will commence starting with health care workers involved in frontline patient facing clinical care.
"Testing capacity is being expanded and is currently prioritised for patients, health care workers involved in frontline patient facing clinical care, and others where recommended by health board medical directors.
"As our testing capacity increases, further guidance will be issued on those who are eligible for testing.
"Members of the public should follow the latest public health advice.”
Almost three-quarters of people say they have changed their behaviour in response to Government guidance on coronavirus, with almost half believing they will become infected, a survey found.
The YouGov survey, commissioned by Imperial College London's Patient Experience Research Centre, was carried after Prime Minister Boris Johnson announced new social distancing measures to control the spread of Covid-19.
The survey, which aimed to capture public sentiment towards the recommendations announced on March 16, found that 93% of adult respondents took at least one measure to protect themselves from infection.
However, while 83% reported washing their hands more frequently, only half said they avoided social events, while 36% said they avoided public transport and 11% avoided going to work.
The survey of 2,108 UK adults on March 17 and 18 found that 88% of people would be willing to self-isolate for seven days if they were advised to by a health professional.
