Background and Objectives: The susceptibility of pregnant patients at term to SARS-CoV-2 infection regarding the ABO and Rh blood group polymorphism was analyzed in this study Materials and Methods: In this prospective study, 457 patients admitted for delivery at term in our hospital, between 1 April 2020 and 31 December 2020 were studied There were 46 positive and 411 SARS-CoV-2 negative patients Their values for RT-PCR, ABO, and Rh blood group analyses, which were determined upon admittance, were studied Results: A slightly higher percentage of infected pregnant patients at term belonged to the A blood group compared with the percentage belonging to the other blood groups;this was also true for the healthy control group For the Rh-negative pregnant patients at term, the odds of being infected with SARS-CoV-2 was OR = 1 22 compared with Rh-positive patients where OR = 1 In our study, the highest risk was found among BIII Rh-negative pregnant patients at term (OR = 3) None of the above differences were statistically significant Conclusions: No significant difference was found between the percentage of ABO or Rh blood groups in SARS-CoV-2 positive patients when compared with SARS-CoV-2 negative patients (p = 0 562)
