BLACK and South Asian patients are more severely affected by Covid-19 than white patients as the way the body functions is a more important factor than poverty or existing health problems, says a new study.
The study of 1,800 hospital patients, carried out at King's College Hospital in south-east London, has found that black people had a higher risk of being admitted to hospital with Covid-19 while South Asian people were more likely to die from it.
According to researchers Biology was a more important factor than poverty or underlying health, and different ethnic groups should be treated differently.
Out of 1,827 adults admitted to the hospital between March and June with confirmed Covid-19, 872 were inner-city residents who gave their ethnicity.
Of these, 48 per cent were black, 33 per cent were white, 12 per cent were mixed ethnicity and 5.6 per cent were of Asian ethnicity - most from South Asia. They were compared with more than 3,000 people living nearby.
The analysis shows that black and mixed ethnicity patients were three times more likely to end up in hospital with Covid-19 compared with white people living in the same area.
However, their chances of survival were not very different from white patients in hospital.
By contrast, South Asian patients did not have a higher risk of being admitted to hospital with Covid-19 than white patients, but they were at higher risk of dying in hospital and needing intensive care.
The researchers found that ethnic minority patients were 10 to 15 years younger than white patients and had more underlying health conditions, particularly type 2 diabetes.
Prof Ajay Shah, consultant cardiologist at King's College Hospital, said the findings were "striking".
"We may need different treatment strategies for different ethnic groups. For black patients, the issue may be how to prevent mild infection progressing to severe, whereas for Asian patients it may be how to treat life-threatening complications."
England's chief medical officer, Chris Whitty, said: "People from black and minority ethnic groups are more severely affected by Covid-19. The research provided important information to help healthcare professionals offer the best possible treatment to minority ethnic patients".
Dr Sonya Babu-Narayan, associate medical director at the British Heart Foundation, said people from BAME backgrounds were more likely to have heart and circulation problems, such as high blood pressure and type 2 diabetes, which would put them more at risk.
It was already known that people from ethnic minority backgrounds are disproportionately affected by serious illness from Covid-19, but the exact reasons were unclear.
