The UK has had the highest number of Covid-19 deaths in healthcare workers than any other country in the world except Russia.
At least 540 frontline staff have died after contracting the virus in England and Wales, official statistics show, second only to Russia, which has recorded 545 deaths.
Amnesty International, a leading human rights organisation, analysed a wide range of data to find more than 3,000 health workers have died after contracting Covid-19 in 79 countries.
It added that this figure is likely to be a 'significant under-estimate' due to under-reporting.
It also noted the UK is one of few countries to distinguish between deaths of social care workers and healthcare workers – increasing the total relative to other nations.

In response to the report, the Department of Health and Social Care said the findings are 'in no way an accurate comparison' with other countries.
The Office for National Statistics (ONS) recorded 268 deaths involving Covid-19 among social care workers were registered in England and Wales between March 9 and May 25.
In the same period, the ONS reported that 272 deaths involving the virus were registered among healthcare staff, including doctors, nurses and midwives, nurse assistants, paramedics and ambulance staff, and hospital porters.
The PA news agency has confirmed the names of 195 health and social care workers who have died after contracting Covid-19 since the start of the outbreak.
Kate Allen, Amnesty International UK's director, said: 'We have to understand whether these deaths were avoidable, and what led to this terrible outcome.
'There appears to have been a catastrophic failure to provide proper PPE (personal protective equipment) and a failure to grapple with the alarmingly high death rates among BAME (black, Asian and minority ethnic) health workers.
'This crisis is far from over and an independent inquiry into the Government's handling of the coronavirus pandemic is urgently needed.'
The human rights organisation called for an 'urgent public inquiry' into the Government's handling of the crisis, to ensure that 'lessons are learned and that there is proper accountability'.
Ministers came under criticism at the start of the Covid-19 pandemic over supplies of PPE, such as masks and gowns, after healthcare workers reported shortages.
In May, a survey by the British Medical Association (BMA) found that almost half of doctors (48 per cent) had sourced their own equipment or relied on a donation when none was available.
Meanwhile, social care providers raised concerns over insufficient equipment in settings, as well as a lack of testing for both staff and residents in the early stages of the pandemic.
Some two billion items of PPE have been provided to healthcare workers, while 28 billion items have been ordered to provide a continuous supply to meet the future needs of those on the front line, according to the Government.
A Department of Health and Social Care spokeswoman said: 'This is in no way an accurate comparison – by Amnesty's own admission, this data is distorted by the fact the UK is one of the few countries to count social care worker deaths.
'We have continuously supplied PPE to the frontline throughout this unprecedented global pandemic, with over two billion items delivered and almost 28billion items ordered to meet future demand, and we have prioritised testing for health and care workers from the outset.'
