People with blood Type A may be more vulnerable to coronavirus than those with Type O: China study finds

According to a Research in Wuhan and Shenzhen, there’s an indication that people with Type A are more vulnerable to the novel coronavirus than those with blood Type O. Blood Type 0 seem more resistant, and this is according to a preliminary study of patients in China with COVID-19.

over 2 000 patients with different blood groups and infected with coronavirus were compared at the Medical research centres in CHINA and found that Type A patients showed a higher rate of infection – and this is the group type that shoes more severe symptoms.

Citing a source report: “People of blood group A might need particularly strengthened personal protection to reduce the chance of infection, Sars-CoV-2-infected patients with blood group A might need to receive more vigilant surveillance and aggressive treatment,” wrote Wang Xinghuan‘s researchers at Zhongnan Hospital of Wuhan University.

Even though the research was preliminary, governments and medical facilities around the world are urged to consider blood types when planning mitigation measures, or when treating patients with Sars-CoV-2

According to a paper published on Medrxiv.org

Blood group A had a significantly higher risk for COVID-1 compared with non-A blood groups, whereas blood group O had a significantly lower risk for the infectious disease compared with non-O blood groups. In addition, the influence of age and gender on the ABO blood group distribution in patients with COVID-19 from two Wuhan hospitals (1,888 patients) were analyzed and found that age and gender do not have much effect on the distribution.


People with blood group A have a significantly higher risk for acquiring COVID-19 compared with non-A blood groups, whereas blood group O has a significantly lower risk for the infection compared with non-O blood groups.
