A NEW study has revealed that healthcare workers from an ethnic minority background are more likely to have built up antibodies to Covid-19.
Nurses, healthcare assistants and junior doctors were more likely to have higher levels of Covid-19 antibodies compared with their more senior medical colleagues, it further said.
The study was done by researchers at the National Institute for Health Research Applied Research Collaboration (ARC) East Midlands and NIHR Leicester Biomedical Research Centre.
Led by Professor Kamlesh Khunti, director of ARC East Midlands and Professor of Primary Care Diabetes and Vascular Medicine at the University of Leicester, the research was focused on hospital staff working at the University Hospitals of Leicester (UHL) NHS trust.
Dr Manish Pareek, Associate Clinical Professor in Infectious Diseases at the University of Leicester was also in the team.
The trust is one of the largest, and most ethnically diverse, hospital trusts in the UK.
In May, it introduced a voluntary blood test to allow staff to find out whether they had developed antibodies against Covid-19.
The researchers were then able to determine which groups of staff were most likely to be ‘seropositive’, the person who had detectable antibodies to a specific condition.
If a person has Covid-19 antibodies present, it means they have been infected with the coronavirus at some point.
Professor Khunti said: “There’s still so much to learn about Covid-19. Given that evidence has already shown there is an increased risk of infection and adverse outcomes in minority ethnic groups, there is an urgent need to understand whether antibody prevalence differs according to ethnicity and other demographic factors including job roles in hospital staff.”
“We discovered that as well as ethnicity, specialty and seniority among NHS staff also impacted antibody prevalence. For example, the anaesthetics and intensive care unit (ICU) teams were less likely to be seropositive than emergency and acute medicine staff,” explained Dr Pareek.
“This could be because of the level of exposure each team has had to infected people when treating patients.”
Evidence has emerged throughout the pandemic that age, gender, deprivation, certain chronic conditions, obesity and race can significantly impact the outcome of the condition for patients.
A national NIHR-funded study, UK-REACH, led by Dr Pareek is also urgently investigating the increased risk of Covid-19 among ethnic minority healthcare workers.
