A group of Chinese scientists claims that people with type A blood are significantly more vulnerable to contract coronavirus than people with type O.
The evidence came to light after academics conducted the preliminary research on more than 2,000 Covid-19 patients at two hospitals in the Chinese city of Wuhan – the source of the global outbreak.
The blood types of 2,173 confirmed patients were compared with 3,694 healthy inhabitants of Wuhan.
They found that those with blood type A were more vulnerable to infection and tended to develop more severe symptoms while those with blood type O had a ‘significantly lower risk’ of getting the disease.
Speaking to South China Morning Post, Gao Yingdai, a researcher with the State Key Laboratory of Experimental Haematology in Tianjin, said while the research may be helpful to medical professionals, the public should not worry too much about the findings.
She added: ‘If you are type A, there is no need to panic. It does not mean you will be infected 100%. ‘If you are type O, it does not mean you are absolutely safe, either. You still need to wash your hands and follow the guidelines issued by authorities.’
