Coronavirus: People With Blood Group A Really At Higher Risk Of Catching COVID-19?

A recent study from China, which has not been peer reviewed yet, suggests a link between having blood group A and a higher risk of getting COVID-19, compared with people who have blood group O. The differentiation by blood grouping plays a critical role during blood donation and transfusion to patients. The recent Chinese study, conducted by researchers including from the Zhongnan Hospital at Wuhan University, retrospectively analysed the blood groups of patients from three hospitals in China, two in Wuhan and one in Shenzhen. At the Wuhan Jinyintan Hospital, they also analysed blood types of 3,694 people who didn’t have COVID-19 and found that 32% had blood group A and 34% had blood group O. Among the 1,775 COVID-19 patients at the hospital, 38% had blood group A and 26% blood group O. But of the 113 COVID-19 patients they analysed, 40% had blood group A and 25% blood group O. At Shenzhen Third People’s Hospital, 29% of the control population (23,386) had blood group A and 39% blood group O. Although there was a significant difference between the patients of COVID-19 with blood groups A and O in the Wuhan hospitals, there was no significant difference in the Shenzhen hospital. They have also not explained why they failed to see a significant difference between the blood groups in the Shenzhen hospital. And given COVID-19 is a pandemic, the sample size that they have analysed is not sufficient to draw firm conclusions. We now need more detailed scientific research to establish the relationship between blood groups and COVID-19 and possibly other viral infections. In the meantime, people should continue to follow the advice provided by their healthcare professionals, government authorities and the WHO to avoid this infection and to control its spread, regardless of which blood group they have.
