Blood Group may have an effect on Coronavirus Vulnerability

A study in Wuhan and Shenzhen, China has indicated that people with blood group A are more likely to be infected by Coronavirus.

According to a paper published on Medrxiv.org on March 11:
"Of 206 patients who had died from Covid-19 in Wuhan, 85 had type A blood, which was 63 per cent more than the 52 with type O. The pattern existed across different age and gender groups."
“It might be helpful to introduce ABO blood typing in both patients and medical personnel as a routine part of the management of Sars-CoV-2 and other coronavirus infections, to help define the management options and assess risk exposure levels of people,” Wang wrote in the paper."
The study was conducted by team of Doctors from across China including  Beijing, Wuhan, Shanghai and Shenzhen. It emphasised that people with blood group O had lesser risk of contacting the Coronavirus infection and responded to treatment more effectively.

The study clearly indicated that:
"People of blood group A might need particularly strengthened personal protection to reduce the chance of infection,” wrote the researchers led by Wang Xinghuan with the Centre for Evidence-Based and Translational Medicine at Zhongnan Hospital of Wuhan University."
"In contrast, blood group O had a significantly lower risk for the infectious disease compared with non-O blood groups”
While the researchers said the study was preliminary and more work was needed, they did urge governments and medical facilities to consider blood type differences when planning mitigation measures or treating patients with the virus, known as Sars-CoV-2.
