Association between ABO blood groups and susceptibility to COVID-19: profile of age and gender in Iraqi patients.

Background: A case-control study was performed to examine age, gender, and ABO blood groups in 1014 Iraqi hospitalized cases with Coronavirus disease 2019 (COVID-19) and 901 blood donors (control group). The infection was molecularly diagnosed by detecting coronavirus RNA in nasal swabs of patients.

Results: Mean age was significantly elevated in cases compared to controls (48.

Evaluating of the association between ABO blood groups and coronavirus disease 2019 (COVID-19) in Iraqi patients.

Background: Susceptibility to the pandemic coronavirus disease 2019 (COVID-19) has recently been associated with ABO blood groups in patients of different ethnicities. This study sought to understand the genetic association of this polymorphic system with risk of disease in Iraqi patients. Two outcomes of COVID-19, recovery and death, were also explored.
