Medical research published by medRxiv supports the statement, but it has also disclosed that the research is yet to be evaluated by various experts.The report published by medRxiv has stated that researchers in China conducted research on more than 2,000 patients infected with the novel coronavirus in Wuhan and Shenzhen and compared with normal people from the corresponding regions. They found that patients with blood type A showed a higher rate of infection compared with non-A blood groups, whereas blood group O has a significantly lower risk for the infection compared with non-O blood groups.

As per the article published by South China Morning Post on 17 March 2020, researchers said that the study was preliminary and it needed more work. They also urged the governments and medical facilities to consider blood type differences when planning mitigation measures or treating patients with the virus.

Since the research is yet to be evaluated and peer-reviewed as of 18 March 2020, the information regarding this is subjected to change.
