Abstract
Introduction: 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. Methods: 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. Results: 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. Conclusion: 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.

Abstract
Background and objectives: In patients with coronavirus disease 2019 (COVID-19), white blood cell (WBC) abnormalities have been found worldwide with significant inter-regional differences. In the present study, we evaluated WBC parameters concerning COVID-19 positivity and severity.
Methods: In this cross-sectional study, total WBC count, absolute count of each type of WBC, neutrophil to lymphocyte ratio (NLR), and lymphocyte to monocyte ratio (LMR) were compared between 150 COVID-19 patients and 150 non-COVID-19 patients presenting with COVID-19-like symptoms. Also, COVID-19 patients were divided into severe and non-severe cases.
Results: The severity of the disease had no significant association with age or gender (p>0.05). Total WBC count, absolute neutrophil count, absolute monocyte count, and NLR were significantly lower (p<0.05), while LMR was significantly higher in COVID-19 patients compared to non-COVID-19 patients (p<0.05). Total WBC count, absolute neutrophil count, and NLR were significantly higher (p<0.05), while absolute eosinophil count and absolute lymphocyte count were significantly lower (p<0.05) in severe COVID-19 patients compared to non-severe patients.
Conclusions: Age is not a predictive factor for the severity of COVID-19. Routine WBC parameters are useful in predicting the severity of the disease in COVID-19 patients and can be used as prognostic indicators. Routine WBC parameters can also be used for repeat RT-PCR testing in COVID-19 suspected patients.
