Evaluating Association between ABO Blood Groups and COVID 19

COVID 19 pandemic caused by SARS-COV2 virus has taken a toll all over the world. The susceptibility of various diseases like Helicobacter Pylori, Hepatitis B virus and Norwalk Virus and even SARS Corona Virus 1 have been associated with ABO blood groups. However, very limited data is available regarding the COVID 19 susceptibility and ABO blood groups.

In the present report we investigated 500 admitted patients who were RTPCR positive for corona virus. Significant Tests were applied to study association of blood groups vis a vis disease severity, ICU admissions and assisted ventilation.

 We found out that Type A blood group is more susceptible to severe COVID 19 infection, even though maximum patients were of type B blood group. We also found that type A blood group needed more ICU admission and assisted ventilation then non type A groups and difference was statistically significant.

Patients with type A blood group COVID 19 patients with type A blood group might require more vigilant surveillance and aggressive treatment measures. Further studies are required to validate the disease susceptibility.
