Background: Pregnant women are evaluated as a high risk category to get COVID-19 infection due to immunocompromised status and hypercoagulable state which was evident in the second wave of COVID-19 in India reporting a high mortality in pregnant patients. Various factors like Diabetes, Hypertension, etc have been correlated with severity of disease. The union of the type of ABO blood group along with severity is still lacking. This current study was done to examine the alliance of the severity of COVID-19 with blood group type in pregnant females.
Materials and Method: The pregnant women’s age, gestation, and parity was recorded. RT- PCR was done for the confirmation of the SARS-CoV-2 status. Rh and ABO blood types were inferred at the time of admission. The chi-square tests and unpaired t-test were employed for the comparison of data.
Results: The mean age of the study population was 26.54±4.57 (18-43 years). There were 35.9% B-blood group, 27.8% A-blood group, 11.4% AB blood group and 24.9% O blood group mothers. Severe Symptomatic COVID-19 was significantly more among AB –ve (40.0%), A –ve (14.8%) and A +ve (14.1%) blood groups.
Conclusion: Blood type O, had less severe progression of the disease.
