Queen Elizabeth has issued a special message for health workers battling the coronavirus, saying their dedication to caring for others "is an example to us all".
The Queen thanked health care staff around the world for their "selfless commitment and diligence" as they put themselves in harm's way to save lives.
A number of National Health Service workers have died after contracting the coronavirus, including nurses Areema Nasreen and Aimee O'Rourke, both mothers of three.
The Queen said: "On the occasion of World Health Day, I want to thank all those working in the healthcare profession for your selfless commitment and diligence as you undertake vitally important roles to protect and improve the health and wellbeing of people across the Commonwealth, and around the world.
"In testing times, we often observe that the best of the human spirit comes to the fore; the dedication to service of countless nurses, midwives and other health workers, in these most challenging of circumstances, is an example to us all.
"My family and I send our enduring appreciation and good wishes."
It came after she used a rare televised message on Sunday evening to urge the British people to show “self-discipline and resolve” and vowed that “we will succeed” in the fight against the coronavirus.
In her special address — only the fifth in her 68-year reign — the Queen thanked NHS staff and other key workers, as well as people who have been staying at home to protect the vulnerable.
