A leaked report into the impact of Covid-19 on black, Asian and minority communities says factors such as racism and social inequality may have contributed to increased risks.
Historic racism may mean that people are less likely to seek care or to demand better personal protective equipment.
It comes in a draft report by Public Health England, seen by the BBC.
Other possible factors include risks linked to occupation, it said.
And inequalities in conditions such as diabetes may increase disease severity.
The report pointed to racism and discrimination as a root cause affecting health and the risk of both exposure to the virus and becoming seriously ill.
It said stakeholders expressed “deep dismay, anger, loss and fear in their communities” as data emerged suggesting Covid-19 was “exacerbating exciting inequalities”.
And it found “historic racism and poorer experiences of healthcare or at work” meant individuals in BAME groups were less likely to seek care when needed or to speak up when they had concerns about personal protective equipment or risk.
- Better data collection about ethnicity and religion, including having this recorded on death certificates to accurately monitor the impact on these communities
- Making it law for health risk assessments to be done for BAME workers and giving them better representation in the health service
- Culturally sensitive public health messaging so that people, particularly those who may not speak English as a first language, understand the advice on how to protect themselves
- Continuing work to tackle racism and discrimination within the health service with a clear commitment to increase diversity in leadership at all levels.
The draft report from Public Health England says questions remain on the role of diet and vitamin D and makes clear no work has been done to review this evidence yet.
A recent review confirmed the risk of death from Covid-19 higher for ethnic minorities. PHE found that people of Bangladeshi heritage were dying at twice the rate of white Britons, while other black, Asian and minority ethnic groups had between 10% and 50% higher risk of death.
On Thursday, a senior academic told the BBC that advice for the government on how to protect BAME communities from coronavirus had yet to be published.
Prof Raj Bhopal, a scientist who had been asked to peer-review the unpublished recommendations report, including contributions from 4,000 stakeholders, said Parliament had “not been told the full truth”.
On Saturday, the British Medical Association sent a letter to Health Secretary Matt Hancock, asking why pages with recommendations to safeguard BAME communities had been “omitted” from the first report.
In a letter, the head of the doctors’ union, Dr Chaand Nagpaul, CBE, called for the recommendations to be published immediately, to tackle “the disturbing reality that the virus is causing disproportionate serious illness and deaths in the BAME community”.
In a letter to Matt Hancock, he wrote: “A clear response is needed as to why these pages and important recommendations were omitted from publication, especially when it is so critical that action is taken to save lives now and reduce race inequalities.”
Speaking on BBC Television, Dr Nagpaul said large numbers of BAME doctors feel let down. “What is critical is that we must avoid further deaths and further ill-health amongst our medical workforce,” he said.
Public Health England said the recommendations would be published next week at the same time that the work is submitted to ministers.
Meanwhile, ethnic minority doctors in the NHS have said they feel “let down” by delays in work to ensure they are protected from coronavirus.
The BMA said many had not received promised risk assessments and redeployment opportunities.
Hospital trusts and other health service bodies have been asked to prioritise risk assessments for BAME staff and other vulnerable groups. But BBC research has found that hundreds of doctors still have not had a risk assessment.
