Blood group A people are at more risk of getting infected with coronavirus or COVID-19, while those people who have blood type O seem to be more on the resistant side, according to the preliminary study of patients which China has done on those patients who have contracted the virus.
Medical researchers in China took blood group patterns of more than 2000 patients who were infected with the virus in Wuhan and Shenzhen. They conducted a study and compared them to local healthy populations. They have found that blood type A patients showed a higher rate of infection which later developed more intense symptoms.
While the researchers did the study which was limited and much work was needed, they did ask the government and medical facilities to consider blood type differences when planning on treating patients with the coronavirus.
“People of blood group A might need particularly strengthened personal protection to reduce the chance of infection” written by Wang Xinghuan with the Centre for Evidence-Based and Translational Medicine at Zhongnan Hospital of Wuhan University.
While on the other hand, blood group or type O has significantly shown lower risk of getting infected by the disease - COVID-19 as when compared with non-O blood groups” according to the paper published on Medrxiv.org
In the list of 206 people who died due to coronavirus or COVID-19 in Wuhan, 85 among them were type A blood which is 63 per cent and type O stands with 52 per cent which is less than type A blood group. This pattern existed across different age groups and gender ratios.
“What might be helpful is to introduce ABO blood type in both patients and medical personnel as a routine part of the management of Sars-CoV2 and other coronavirus infections to help in defining the management options and better access of risk exposure of people” Wang wrote in the paper of research.
