Frontline NHS staff in England will start being tested this weekend to see whether they have coronavirus.
Workers with symptoms or those who live with people who have symptoms will be checked - starting with hundreds of critical care doctors and nurses.
Tests for A&E staff, paramedics and GPs are expected to follow, and later social care staff will be tested.
The number of people who have died with the virus in the UK rose by 181 to 759 on Friday, with 14,543 confirmed cases.
Until now, only patients in hospital with flu-like symptoms were being routinely tested.
